Jan Ohlberger, PhD


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


My research aims at understanding 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, as well as lab experiments and fieldwork.  


Keywords: climate change, density dependence, fisheries, life-history, metabolic scaling, population dynamics, size-structure, species interactions, temperature, thermal adaptation
