Research Scientist at zeroK NanoTech
I am presently a Postdoctoral Fellow working at the startup company zeroK NanoTech.  My current research is on the application of atomic physics and laser cooling techniques to the development of a cold ion source for focused ion beam (FIB) instruments.  We are collaborating with the National Institute of Standards and Technology (NIST) Center for Nanoscale Science and Technology (CNST) on this project.  My appointment at zeroK NanoTech is enabled by the Small Business Postdoctoral Research Diversity Fellowship from the American Society of Engineering Education (ASEE); this is an NSF-supported fellowship.

In my other recent research I have studied rubidium atoms in highly excited electronic states, known as Rydberg states.  In early 2014 I used their sensitivity to electromagnetic fields to develop an atom-based sensing technique for RF and mm-wave electric fields.  This work was in collaboration with researchers at NIST, Boulder.  In my Ph.D. thesis work I studied the interactions between Rydberg atoms.  These are relevant to quantum information processing, and also play a role in energy transfer in atomic gases.

University of Michigan
Researcher
Collaboration with NIST researchers Chris Holloway and Josh Gordon.

Developing atom-based measurements of RF and mm-wave electric field strengths, for traceability to fundamental constants.

Recently demonstrated the sub-wavelength resolution of this sensing technique, which is based on Autler-Townes splitting of Rydberg states as detected by electromagnetically induced transparency.
University of Michigan, Raithel Lab
Graduate Student Research Assistant
Imaged spatial correlations between highly excited (Rydberg) atoms in a cold (200 microKelvin) atomic vapor.  Obtained images of the Rydberg excitation blockade, and studied the dependence of the blockade on laser parameters and external potentials.

Published two first-author articles, including one in Physical Review Letters.
Designed, built, and calibrated a Rydberg atom imaging system.
Programmed all experimental control and analysis software.
Performed all data analysis and interpretation.
Mentored students in several electronics and optics project, and currently training a new student on my project.
