Profile

Research Interests

My research interest lie in trophodynamics of marine systems, biostatistics and zooplankton population dynamics. Zooplankton are sensitive indicators of climate change and provide a variety of ecosystem services, such as fishery production and nutrient cycling; our ability to understand the effects of environmental variability on marine systems depends on our capability to predict changes in zooplankton abundance. For my PhD thesis I will establish mechanistic explanations of the linkages between environmental forcing and zooplankton demography by employing quantitative approaches to integrate observational data collected at a variety of time-scales. Furthermore, I plan to determine zooplankton functional groups based on their similar response to environmental change. My model system is Rivers Inlet, a fjord on the Central coast of British Colombia, Canada. More information about this interdisciplinary project can be found at http://riversinlet.eos.ubc.ca.
