​

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.
