Research areas

I focus on solving biological problems through data synthesis and mathematical models and work on a variety of research projects, including:

My graduate students and postdocs are currently working on modeling herring in Prince William Sound, improving Bayesian convergence time for fisheries stock assessments, developing new methods for data-limited stock assessments, examining the effects of catch shares on fisheries and ecosystems, assessing the status of blue whales in the Pacific and estimating the frequency of black swan events in ecological data.

Prospective graduate students: Students in my lab usually have skills in math, statistics, and programming. If you are interested in joining my fledgling lab, please send me an email with (1) your CV, (2) unofficial transcripts, (3) a couple of paragraphs about your research interests, (4) your GRE scores, if available, and (5) a recent written example of your work. I will not make any decisions about incoming students until Jan-Feb of the year of admission.
