# CURRENT POSITION

Research Fishery Biologist, NOAA Fisheries (supervisor: Guy W.
Fleischer, <Guy.Fleischer@noaa.gov>).

# EDUCATION

*2001:* Ph.D. in Oceanography, Texas A&M University, College Station,
TX\
*1996:* B.A. in Biology, *summa cum laude*, Bucknell University,
Lewisburg, PA

# RESEARCH INTERESTS

My research interests have included understanding how physical
oceanographic features influence the distribution of zooplankton, fish,
and other higher predators, applying acoustic methods to the study of
patterns in zooplankton and fish, and learning how marine ecosystems
respond to climate change.

As a member of the FRAM Division Acoustics Team, I'm currently using
acoustics in a synoptic approach to the study of the stock size,
ecology, and distribution of Pacific hake and their prey in the
California Current System. The Acoustics Team is charged with providing
acoustic assessments of commercially- and ecologically-valuable
fisheries off the west coast of North America, which includes the U.S.
portion of an established joint U.S.-Canadian Pacific hake survey
program. These regular assessments are key to estimation of fish stock
size and act as the foundation of advice on harvest levels. My
particular interests in this work include improvements to current
acoustic survey techniques, the application of new sonar and sensor
technology to fisheries research problems, and a synoptic approach to
the study of the ecology and distribution of hake and their prey.

# PREVIOUS RESEARCH EXPERIENCE 

*(9/01-09/02):* I was a post-doctoral researcher with Dr. Richard D.
Brodeur (<rick.brodeur@noaa.gov>) and Dr. William T. Peterson as part of
the U.S. Global Oceans Ecosystems Dynamics (GLOBEC;
<http://globec.oce.orst.edu/groups/nep/>) program in the northeast
Pacific Ocean. I explored the influence of mesoscale circulation
features upon the patchiness of zooplankton and nekton in the northern
California Current System, and the implications for the foraging of
higher-trophic-level predators.

*(7/96-8/01):* My dissertation research at Texas A&M involved using a
combination of acoustic backscattering strength data collected with a
153 kHz ADCP (Acoustic Doppler Current Profiler) and plankton samples
gathered with a MOCNESS (Multiple Opening-Closing Net Environmental
Sensing System) to make inferences about zooplankton and micronekton
standing stocks (Dr. Douglas C. Biggs, Committee Chair). I examined how
oceanographic processes (*e.g.* mesoscale eddies) drove the magnitude
and spatio-temporal variability in observed biomass patterns in the
northern Gulf of Mexico, as well as the implications of those patterns
for the distribution of cetaceans and seabirds in that region.

*(6/99-7/99):* I co-authored a literature review of deepwater
zooplankton, micronekton, and ichthyoplankton of the Gulf of Mexico for
Continental Shelf Associates and the U.S. Minerals Management Service
(MMS) with Dr. Douglas C. Biggs. A manuscript from this work was
published by the journal *Gulf of Mexico Science*.

*(07/96-05/99):* I participated in the fieldwork (3 cruises) and
analysis portions of the \'GulfCet II\' study of cetacean abundance and
distribution in the northeastern Gulf of Mexico. I co-authored portions
of the final report (on the biological oceanography and cetacean habitat
association components of the project) to the agency sponsors, which
were the U.S. Geological Survey-Biological Resources Division (USGS-BRD)
and the U.S. Minerals Management Service (MMS).

*(2/96-5/96):* During my senior undergraduate year at Bucknell
University, I completed an independent research project comparing water
quality in two stream systems near Lewisburg, PA (Dr. Wayne McDiffett,
Advisor).

*(6/95-8/95):* In the summer of 1995, I was a volunteer involved in
stream ecology research investigating the predatory interactions and
habitat preferences of freshwater meiofauna with the lab of Dr. Margaret
Palmer, Department of Zoology, University of Maryland at College Park.

*(3/95-5/95):* As a junior year undergraduate, I completed an
independent research project in the SEA Semester Program entitled
\"Diversity, Composition, and Biomass of Phytoplankton Assemblages in
the Sub-Tropical North Atlantic.\" The research platform was the SSV
*Corwith Cramer*, Sea Education Association, Woods Hole, MA.

# FIELD EXPERIENCE

(AUV) training and deployments off San Diego
