description: Intense terahertz laser field is shown to have a profound effect on the electronic and optical properties of quantum rings, where the isotropic and anisotropic quantum rings can now be treated on equal footing. We have demonstrated that in isotropic quantum rings the laser field creates irregular AB oscillations that are usually expected in anisotropic rings. Further, we have shown for the first time that intense laser fields can restore the {\it isotropic} physical properties in anisotropic quantum rings. In principle, all types of anisotropies (structural, effective masses, defects, etc.) can evolve as in isotropic rings, in our present approach. Most importantly, we have found a continuous evolution of the energy spectra and intraband optical characteristics of structurally anisotropic quantum rings to those of isotropic rings, in a controlled manner, with the help of a laser field.

description: We present a comparative study of stellar winds in classical supergiant high mass X-ray binaries (SgXBs) and supergiant fast X-ray transients (SFXTs) based on the analysis of publicly available out-of-eclipse observations performed with Suzaku and XMM-Newton. Our data-set includes 55 observations of classical SgXBs and 21 observations of SFXTs. We found that classical SgXBs are characterized by a systematically higher absorption and luminosity compared to the SFXTs, confirming the results of previous works in the literature. Additionally, we show that the equivalent width of the fluorescence Kα iron line in the classical SgXBs is significantly larger than that of the SFXTs (outside X-ray eclipses). Based on our current understanding of the physics of accretion in these systems, we conclude that the most likely explanation of these differences is to be ascribed to the presence of mechanisms inhibiting accretion for most of the time in the SFXTs and leading to a much less efficient photoionization of the stellar wind compared to classical SgXBs.We do not find evidence for the previously reported anti-correlation between the equivalent width of the fluorescence iron line and the luminosity of SgXBs.

description: Neutral silicon vacancy (SiV0) centers in diamond are promising candidates for quantum network applications because of their exceptional optical properties and spin coherence. However, the stabilization of SiV0 centers requires careful Fermi level engineering of the diamond host material, making further technological development challenging. Here, we show that SiV0 centers can be efficiently stabilized by photoactivated itinerant carriers. Even in this nonequilibrium configuration, the resulting SiV0 centers are stable enough to allow for resonant optical excitation and optically detected magnetic resonance. Our results pave the way for on-demand generation of SiV0 centers as well as other emerging quantum defects in diamond.

description: We study the dynamics of many atoms in the recently proposed Single Atom Transistor setup [A. Micheli, A. J. Daley, D. Jaksch, and P. Zoller, Phys. Rev. Lett. 93, 140408 (2004)] using recently developed numerical methods. In this setup, a localised spin 1/2 impurity is used to switch the transport of atoms in a 1D optical lattice: in one state the impurity is transparent to probe atoms, but in the other acts as a single atom mirror. We calculate time-dependent currents for bosons passing the impurity atom, and find interesting many body effects. These include substantially different transport properties for bosons in the strongly interacting (Tonks) regime when compared with fermions, and an unexpected decrease in the current when weakly interacting probe atoms are initially accelerated to a non-zero mean momentum. We also provide more insight into the application of our numerical methods to this system, and discuss open questions about the currents approached by the system on long timescales.

description: We theoretically investigate pump-probe optical responses in the two-dimensional extended Hubbard model describing cuprates by using a time-dependent Lanczos method. At half filling, pumping generates photoinduced absorptions inside the Mott gap. A part of low-energy absorptions is attributed to the independent propagation of photoinduced holons and doublons. The spectral weight just below the Mott gap increases with decreasing the on-site Coulomb interaction $U$. We find that the next-nearest-neighbor Coulomb interaction $V_1$ enhances this $U$ dependence, indicating the presence of biexcitonic contributions formed by two holon-doublon pairs. Photo-pumping in hole-doped systems also induces spectral weights below remnant Mott-gap excitations, being consistent with recent experiments. The induced weights are less sensitive to $V_1$ and may be related to the formation of a biexcitonic state in the presence of hole carriers.

description: The fight against tuberculosis (TB), has been further complicated by both the emergence of multidrug resistant strains of the organism, along with its coinfection with Human Immunodeficiency Virus (HIV). Since current TB regimens reduce the efficacy of highly active antiretroviral therapies (HAART) by cytochrome induction, TB and HIV cannot be treated simultaneously. With mortality rates of TB-HIV coinfected people rising globally, the scientific community has seen renewed vigor in the search for a novel, noncytochrome inducing antitubercular, agent. In a screen conducted at the University of Utah, the natural product amicetin was identified as a potential scaffold with antitubercular activity, noncytotoxicity, and compatibility with HAART. The first generation of analogs aimed to simultaneously reduce the complexity involved in the synthesis of the disaccharide moiety and replace the acid labile glycosidic linkage. It was shown with analog CZ-02-023 that despite the removal of eight stereocenters from amicetin, potency (IC50 of 0.98 µM against Mtb) and on-target selectivity (SIRR/E.coli =111) could be retained. The crystal structure of Ami bound to the Peptidyl Transferase Center (PTC) of the T. thermophiles 70S ribosome elucidated amicetin's important binding interactions, includes a cation-π interaction of its terminal aminosugar with A2450 and a Watson-Crick base pair between its cytosine portion and G2262. Additionally, hydrogen bonding of amicetin's α-methylserine moiety with the phosphate backbone of G2506 and π-π stacking with the p-aminobenzoyl moiety with A2613 were observed. Not only did this data demonstrate amicetin's binding to the therapeutically unexploited PTC, it served to guide intelligent SAR development that led to the synthesis of CZ-02033 and CZ-02039 with broad spectrum activity and faded on-target selectivity (SIRR/E.coli < 3). The loss of on-target selectivity prompted further modifications to the Cytosine-PABA region in a series of third generation analogs based on the knowledge of the crystal structure of the Ami-70S-tRNA ternary complex. The third generation piperazinyl urea analogs including CZ-02-117, CZ-02118, and CZ-02-132 increased selectivity (SIRR/E.coli >400). Efforts continue to further the development of amicetin-based broad-spectrum antibiotics.
On Robust Cross-View Consistency in Self-Supervised Monocular Depth Estimation

description: Remarkable progress has been made in self-supervised monocular depth estimation (SS-MDE) by exploring cross-view consistency, e.g., photometric consistency and 3D point cloud consistency. However, they are very vulnerable to illumination variance, occlusions, texture-less regions, as well as moving objects, making them not robust enough to deal with various scenes. To address this challenge, we study two kinds of robust cross-view consistency in this paper. Firstly, the spatial offset field between adjacent frames is obtained by reconstructing the reference frame from its neighbors via deformable alignment, which is used to align the temporal depth features via a Depth Feature Alignment (DFA) loss. Secondly, the 3D point clouds of each reference frame and its nearby frames are calculated and transformed into voxel space, where the point density in each voxel is calculated and aligned via a Voxel Density Alignment (VDA) loss. In this way, we exploit the temporal coherence in both depth feature space and 3D voxel space for SS-MDE, shifting the "point-to-point" alignment paradigm to the "region-to-region" one. Compared with the photometric consistency loss as well as the rigid point cloud alignment loss, the proposed DFA and VDA losses are more robust owing to the strong representation power of deep features as well as the high tolerance of voxel density to the aforementioned challenges. Experimental results on several outdoor benchmarks show that our method outperforms current state-of-the-art techniques. Extensive ablation study and analysis validate the effectiveness of the proposed losses, especially in challenging scenes.

description: Harlequin frogs have suffered severe declines across the Neotropics. We present a population assessment for a recently discovered population of Atelopus varius from Costa Rica. Using mark-recapture methods from September 2011 to February 2013, we estimated survival and recruitments parameters using Cormack-Jolly-Seber models. We obtained 222 captures and estimated low recruitment rates and high seniority. Given estimates of population growth rates close to zero, the observed population seems to be stable during the study. However, contrary to expectations for seasonally reproducing species like A. varius, we did not find an increase in recruitment rates between dry and rainy season. We provide details on ongoing threats for the population, as well as propose conservation actions to mitigate these threats.

description: The Large Synoptic Survey Telescope (LSST) is an 8-m optical ground-based telescope being built on Cerro Pachón in Chile. LSST will survey half the sky every few nights in six optical bands for ten years (imaging each part of the sky about 1000 times). The pipelines developed for LSST boast state-of-the-art image processing algorithms, many of which were developed specifically for the high throughput data. While developed for a specific surveys these algorithms have the potential for broad uptake in the astronomical community if they can be made easily acessible and usable. We introduce here a scalable framework for the analysis of large imaging surveys, designed to operate as a cloud service, incorporate new or legacy image processing algorithms, and to support and optimize complex analysis workflows.

description: We study the density profiles of collapsed galaxy-size dark matter halos with masses 1e11-5e12 Msun focusing mostly on the halo outer regions from the formal virial radius Rvir up to 5-7Rvir. We find that isolated halos in this mass range extend well beyond Rvir exhibiting all properties of virialized objects up to 2-3Rvir: relatively smooth density profiles and no systematic infall velocities. The dark matter halos in this mass range do not grow as one naively may expect through a steady accretion of satellites, i.e., on average there is no mass infall. This is strikingly different from more massive halos, which have large infall velocities outside of the virial radius. We provide accurate fit for the density profile of these galaxy-size halos. For a wide range (0.01-2)Rvir of radii the halo density profiles are fit with the approximation rho=rho_s exp(-2n[x^{1/n}-1])+rho_m, where x=r/r_s, rho_m is the mean matter density of the Universe, and the index n is in the range n=6-7.5. These profiles do not show a sudden change of behavior beyond the virial radius. For larger radii we combine the statistics of the initial fluctuations with the spherical collapse model to obtain predictions for the mean and most probable density profiles for halos of several masses. The model give excellent results beyond 2-3 formal virial radii.

description: Counterfactual Explanations (CE) face several unresolved challenges, such as ensuring stability, synthesizing multiple CEs, and providing plausibility and sparsity guarantees. From a more practical point of view, recent studies [Pawelczyk et al., 2022] show that the prescribed counterfactual recourses are often not implemented exactly by individuals and demonstrate that most state-of-the-art CE algorithms are very likely to fail in this noisy environment. To address these issues, we propose a probabilistic framework that gives a sparse local counterfactual rule for each observation, providing rules that give a range of values capable of changing decisions with high probability. These rules serve as a summary of diverse counterfactual explanations and yield robust recourses. We further aggregate these local rules into a regional counterfactual rule, identifying shared recourses for subgroups of the data. Our local and regional rules are derived from the Random Forest algorithm, which offers statistical guarantees and fidelity to data distribution by selecting recourses in high-density regions. Moreover, our rules are sparse as we first select the smallest set of variables having a high probability of changing the decision. We have conducted experiments to validate the effectiveness of our counterfactual rules in comparison to standard CE and recent similar attempts. Our methods are available as a Python package.

description: Space radiation research has progressed rapidly in recent years, but there remain large uncertainties in predicting and extrapolating biological responses to humans. Exposure to cosmic radiation and Solar Particle Events may pose a critical health risk to future spaceflight crews and can have a serious impact to all biomedical aspects of space exploration. The relatively minimal shielding of the cancelled 1960's Manned Orbiting Laboratory program's space vehicle and the high inclination polar orbits would have left the crew susceptible to high exposures of cosmic radiation and high dose-rate SPEs that are mostly unpredictable in frequency and intensity. In this study, we have modeled the nominal and off-nominal radiation environment that a MOL-like spacecraft vehicle would be exposed to during a 30-day mission using high performance, multi-core computers. Projected doses from a historically large SPE (e.g. the August 1972 solar event) have been analyzed in the context of the MOL orbit profile, providing an opportunity to study its impact to crew health and subsequent contingencies.It is reasonable to presume that future commercial, government, and military spaceflight missions in low-Earth orbit will have vehicles with similar shielding and orbital profiles. Studying the impact of cosmic radiation to the mission's operational integrity and the health of MOL crewmembers provides an excellent surrogate and case-study for future commercial and military spaceflight missions.

description: We build the electromagnetic trace anomaly effective term for a generalized linear sigma model with two chiral nonets, one with a quark-antiquark structure, the other one with a four quark content. In the leading order of this framework, we study the decays into two photons of the lowest isosinglet scalar mesons. We find that the direct inclusion of underlying mixing among two- and four-quark components in the trace anomaly term is essential in order for the model prediction to agree with the available experimental data on decay width of $f_0(980)$ to two photons. Consequently, this sets a lower bound of 0.5 KeV on the decay with of $f_0(500)$ to two photons.

description: Titan's northern high latitudes host many large hydrocarbon lakes. Like water lakes on Earth, Titan's lakes are constantly subject to evaporation. This process strongly affects the atmospheric methane abundance, the atmospheric temperature, the lake mixed layer temperature, and the local wind circulation. In this work we use a 2D atmospheric mesoscale model coupled to a slab lake model to investigate the effect of solar and infrared radiation on the exchange of energy and methane between Titan's lakes and atmosphere. The magnitude of solar radiation reaching the surface of Titan through its thick atmosphere is only a few $Wm^{-2}$. However, we find that this small energy input is important and is comparable in absolute magnitude to the latent and sensible heat fluxes, as suggested in the prior study by Rafkin and Soto (2020). The implementation of a gray radiative scheme in the model confirms the importance of radiation when studying lakes at the surface of Titan. Solar and infrared radiation change the energy balance of the system leading to an enhancement of the methane evaporation rate, an increase of the equilibrium lake temperature almost completely determined by its environment (humidity, insolation, and background wind), and a strengthening of the local sea breeze, which undergoes diurnal variations. The sea breeze efficiently transports methane vapor horizontally, from the lake to the land, and vertically due to rising motion along the sea breeze front and due to radiation-induced turbulence over the land.

Technicolor predicts that technipions, pi_T, decay dominantly into b-bbar, b-cbar, or bbar-c, depending on their charge. In these events b and c quarks are identified by their secondary decay vertices within jets. Two analysis methods based on topological variables are presented. Since no excess above the standard model prediction was found, the result is presented as an exclusion in the pi_T vs. rho_T mass plane for a given set of model parameters.

description: We propose an effective method to optimize the working parameters (WPs) of microwave-driven quantum logical gates implemented with multi-level physical qubits. We show that by treating transitions between each pair of levels independently, intrinsic gate errors due primarily to population leakage to undesired states can be estimated accurately from spectroscopic properties of the qubits and minimized by choosing appropriate WPs. The validity and efficiency of the approach are demonstrated by applying it to optimize the WPs of two coupled rf SQUID flux qubits for controlled-NOT (CNOT) operation. The result of this independent transition approximation (ITA) is in good agreement with that of dynamic method (DM). Furthermore, the ratio of the speed of ITA to that of DM scales exponentially as 2^n when the number of qubits n increases.

description: This project investigates the representation of American actresses Mary Martin and Jane Fonda during the Vietnam War and why they are inversely committed to American cultural memory. Mary Martin's involvement as a Broadway performer in an active war zone reinforced her legacy as America's sweetheart. Jane Fonda's role as a feminist, antiwar protester constructed her reputation as an un-American traitor. Both women promoted different agendas of American interventionism in Asia based on their interaction styles with Asian nationals and relationships with the US government.

description: We present timing and spectral analysis of a sample of seven hard X-ray selected Cataclysmic Variable candidates based on simultaneous X-ray and optical observations collected with XMM-Newton , complemented with Swift/BAT and INTEGRAL/IBIS hard X-ray data and ground-based optical photometry. For six sources, X-ray pulsations are detected for the first time in the range $\rm \sim296-6098\,s$, identifying them as members of the magnetic class. Swift J0927.7-6945, Swift J0958.0-4208, Swift J1701.3-4304, Swift J2113.5+5422, and possibly PBC J0801.2-4625, are Intermediate Polars (IPs), while Swift J0706.8+0325 is a short (1.7 h) orbital period Polar, the 11$^{\rm th}$ hard X-ray selected identified so far. X-ray orbital modulation is also observed in Swift J0927.7-6945 (5.2 h) and Swift J2113.5+5422 (4.1 h). Swift J1701.3-4304 is discovered as the longest orbital period (12.8 h) deep eclipsing IP. The spectra of the magnetic systems reveal optically thin multi-temperature emission between 0.2 and 60 keV. Energy dependent spin pulses and the orbital modulation in Swift J0927.7-6945 and Swift J2113.5+5422 are due to intervening local high density absorbing material ($\rm N_H\sim10^{22-23}\,cm^{-2}$). In Swift J0958.0-4208 and Swift J1701.3-4304, a soft X-ray blackbody (kT$\sim$50 and $\sim$80 eV) is detected, adding them to the growing group of "soft" IPs. White dwarf masses are determined in the range $\rm \sim0.58-1.18\,M_{\odot}$, indicating massive accreting primaries in five of them. Most sources accrete at rates lower than the expected secular value for their orbital period. Formerly proposed as a long-period (9.4 h) novalike CV, Swift J0746.3-1608 shows peculiar spectrum and light curves suggesting either an atypical low-luminosity CV or a low mass X-ray binary.

description: We develop genetic algorithms for searching quantum circuits, in particular stabilizer quantum error correction codes. Quantum codes equivalent to notable examples such as the 5-qubit perfect code, Shor's code, and the 7-qubit color code are evolved out of initially random quantum circuits. We anticipate evolution as a promising tool in the NISQ era, with applications such as the search for novel topological ordered states, quantum compiling, and hardware optimization.

description: The interplay of dynamics and structure is a common theme in both mathematics and biology. In this thesis, the author develops and analyzes mathematical models that give insight into the dynamics and structure of a variety of biological applications. The author presents a variety of contributions in applications of mathematics to explore biological systems across several scales. First, she analyzes pattern formation in a partial differential equation model based on two interacting proteins that are undergoing passive and active transport, respectively. This work is inspired by a longstanding problem in identifying a biophysical mechanism for the control of synaptic density in C. elegans and leads to a novel mathematical formulation of Turing-type patterns in intracellular transport. The author also demonstrates the persistence of these patterns on growing domains, and discusses extensions for a two-dimensional model. She then presents two models that explore how stochastic processes affect intracellular dynamics. First, the author and her collaborators derive effective stochastic differential equations that describe intermittent virus trafficking. Next, she shows how ion channel fluctuations lead to subthreshold oscillations in neuron models. In the final chapter, she discusses two projects for ongoing and future work: one on modeling parasite infection on dynamic social networks, and another on the bifurcation structure of localized patterns on lattices. All of these projects, presented together, chronicle the journey of the author through her mathematical development and attempts to identify, discover, create, and communicate mathematics that inspires and excites.

description: Dispersal is the main process leading to gene flow in populations. Gene flow influences the spatial distribution of populations, individuals and genes. Natural populations are typically subdivided, or structured, in space and genetic composition in part due to limited dispersal. Understanding how genetic variation is partitioned and the factors that govern this process is a major goal of evolutionary biologists because the degree to which populations are structured affects rates of local adaptation, speciation and extinction. In my dissertation I examine how one life history trait, phoretic dispersal, influences gene flow and genetic differentiation in populations. Here I compare related and sympatric species that are ecologically very similar, but explicitly differ in dispersal behavior. Wing lice (Columbicola columbae) frequently engage in phoresis or "hitchhike" on the pigeon lousefly (Pseudolynchia canariensis), while body lice (Campanulotes compar) do not. In the first part of my dissertation I characterize the genetic makeup of wing and body lice populations on a local scale. I found that in a geographic area where flies occur, wing lice have significantly less population genetic structure than body lice. Next I identified geographic areas where flies are absent from pigeon populations. Finally, I compared patterns of genetic differentiation on a global scale for wing and body lice populations. I found that in areas without flies, wing lice and body lice have similar patterns of genetic differentiation. These findings strongly suggest that ongoing phoretic dispersal erodes population genetic structure and enhances population connectivity for wing lice.

description: Understanding patterns and processes underlying the structure and assembly of ecological communities is a major goal of ecology. Community assembly involves a balance between dispersal events and interactions with biotic and abiotic elements that make up the local environment. Determining which processes dominate and under what circumstances remains unclear for parasite communities. Parasite communities of deer mice are examined to determine whether host traits, parasite interactions, and/or parasite dispersal is important in structuring within host parasite community structure. The results suggest that within host parasite communities accumulate in heavier, older hosts. Parasite dispersal plays a role in structuring parasite communities in deer mice. Helminths and ticks accumulated in older hosts, while fleas and lice did not. Helminths and lice were predicted to accumulate in older hosts because they are associated with their hosts for longer periods of time than ticks and fleas. In studies of parasite communities, it is important to document most, if not all, parasites of interest on or in a host. Using histopathology, I show that deer mice are not infected by parasites in other tissues that are not typically examined during standard parasitological surveys. I also survey rodents in the Great Basin for diseases that are caused by both infectious and non-infectious sources. Two pathogens were found in deer mice: the fungus Emmonsia crescens and the nematode Capillaria hepatica. The most common disease was extramedullary hematopoiesis (11%). I also investigated how habitat change influences species turnover. A major change in the environments of the Intermountain West is the expansion of pinyon-juniper woodlands (P-J). Rodent communities in the Great Basin are assessed to document species turnover following P-J conversion. I found that there was a diversity deficit (immigration credit) following P-J conversion because immigration of new species into P-J converted areas is slower than local species extinction. Diversity may increase if the immigrating species become more abundant. Parasites are also subject to environmental change, but little empirical data exist about how parasites will respond. Resampling historical sites following environmental change suggests that helminth diversity increased throughout the Great Basin region. This change was driven by a decrease in the prevalence and abundance of the pinworm Syphacia peromysci, making the relative abundances of helminth species more even. Complex life cycle parasites appear to be more stable to environmental change than those with direct life cycles because, in this system, complex life cycle parasites have lower host specificity.

description: We observed twelve nearby HI -detected early-type galaxies (ETGs) of stellar mass $\sim 10^{10}M\odot \leq M_* \leq \sim 10^{11}M\odot$ with the Mitchell Integral-Field Spectrograph, reaching approximately three half-light radii in most cases. We extracted line-of-sight velocity distributions for the stellar and gaseous components. We find little evidence of transitions in the stellar kinematics of the galaxies in our sample beyond the central effective radius, with centrally fast-rotating galaxies remaining fast-rotating and centrally slow-rotating galaxies likewise remaining slow-rotating. This is consistent with these galaxies having not experienced late dry major mergers; however, several of our objects have ionised gas that is misaligned with respect to their stars, suggesting some kind of past interaction. We extract Lick index measurements of the commonly-used H$β$, Fe5015, Mg\, b, Fe5270 and Fe5335 absorption features, and we find most galaxies to have flat H$β$ gradients and negative Mg, b gradients. We measure gradients of age, metallicity and abundance ratio for our galaxies using spectral fitting, and for the majority of our galaxies find negative age and metallicity gradients. We also find the stellar mass-to-light ratios to decrease with radius for most of the galaxies in our sample. Our results are consistent with a view in which intermediate-mass ETGs experience mostly quiet evolutionary histories, but in which many have experienced some kind of gaseous interaction in recent times.

Imaging Bright Spots in the Accretion Flow Near the Black Hole Horizon of Sgr A*

description: Images from the vicinity of the black hole horizon at the Galactic centre (Sgr A*) could be obtained in the near future with a Very Large Baseline Array of sub-millimetre telescopes. The recently observed short-term infrared and X-ray variability of the emission from Sgr A* implies that the accretion flow near the black hole is clumpy or unsteady. We calculate the appearance of a compact emission region (bright spot) in a circular orbit around a spinning black hole as a function of orbital radius and orientation. We find that the mass and spin of the black hole can be extracted from their generic signatures on the spot image as well as on the lightcurves of its observed flux and polarisation. The strong-field distortion remains noticeable even when the spot image is smoothed over the expected ~20 microarcsecond resolution of future sub-millimetre observations.

Urban planning

description: This dissertation aims to define the field of ecological planning. It uses interdisciplinary, mixed methods research to advance the understanding of theory, practice, and process at the intersection of science and the built environment. In theory, this dissertation defines ecological planning in terms of the "ecological paradigm": a concept elaborated by scholars of environmental history. This concept ties together the implicit theory of ecological planning, as described by experts within the field, and makes that theory explicit in one rigorous, coherent, interwoven analysis. As we will see, ecological planning is at the leading edge of a temporal, accretive, and aspirational shift to this paradigm, as both science and urbanism move towards one another into a new inter- or transdisciplinary space. In practice, this dissertation identifies the points of consensus that characterize research and application at the intersection of biophysical science and the built environment. It draws on the insights of expert scientists and urbanists, from both academia and professional practice, whose work focuses on that intersection. Their key points of agreement include principles for ecological planning practice, policies and governance structures, direct applications, the elements of successful projects, and the intricacies of interdisciplinary and collaborative work. In process, this dissertation creates a new conceptual framework for ecological planning which is holistic, nonlinear, dynamic, and collaborative. That framework synthesizes the workflow of diverse ecological planning experts, to show how processes of science and urbanism may become further integrated. It weaves the preceding theoretical and practical perspectives together, defining ecological planning as a form of transdisciplinary praxis. Using this new definition, the dissertation then assess the current state of ecological planning and makes recommendations for the field to realize its full potential, as the social-ecological future of planning in a social-ecological world.
