Jan Ohlberger, PhD


Research Scientist, School of Aquatic and Fishery Sciences, University of Washington


My research is motivated by the desire to understand how organisms interact with each other and the biotic environment, and how aquatic ecosystems are affected by human activity. Specifically, I study how fish populations in marine and freshwater ecosystems respond to climate change, fishing, and diseases. I am interested in the ecological, physiological, and evolutionary aspects of these responses. To investigate my research questions, I use numerical models such as age- or size-structured population models in combination with empirical data, statistical models, time-series analysis, simulation modeling, lab experiments and fieldwork.
