Research and Professional Interests:

I study population dynamics with a focus on marine species. I am interested in how environmental and trophic interactions regulate fluctuations in demographics (i.e. recruitment, growth, reproduction & mortality) and how fisheries management impacts dynamics in space and time. My research integrates field & laboratory experiments, field surveys, statistical analysis, quantitative theory and simulation modeling. Focal taxa include sea urchins, macroalgae, forage fish, reef fish and abalone.
