I completed a PhD on Biological Oceanography, with main research interest on phytoplankton ecology and photo-physiology, primary production, ocean color and remote sensing of the ocean, coastal water bio-optics and riverine-coastal oceanography. The main focus of the current project is to combine high resolution satellite remote sensing with in situ oceanographic sampling to examine the spatial and temporal variability of the physical, chemical and biological properties of the coastal oceans from British Columbia to Southeast Alaska. The project aims to address what are the spatial and temporal dynamics of the biogeochemical properties of the coastal oceans of British Columbia and Southeast Alaska; what are the dominant bottom-up control processes driving the dynamics of these regions; and what are the implications of bottom-up processes for regional primary productivity, and the foraging habitat available to migrating juvenile salmon.

Research Areas:
My broad interests are in zooplankton ecology and biological oceanography. For my PhD research, I determined how short-term variations in food quantity, food quality, and primary productivity influence zooplankton communities in coastal marine ecosystems on the west coast of Canada and in the tropical waters of Guanabara Bay, Brazil. The main goal of my postdoctoral work is to investigate the level of synchrony between phytoplankton and zooplankton phenology in the Salish Sea. Time-series data for phytoplankton will be derived from various sources (satellite imagery, buoy data, ferry data, citizen science data, and research cruise data) and then coupled with historical and present zooplankton data. By looking at long-term spatial data of phytoplankton and zooplankton, we can identify their response to different climate drivers (e.g. SST, wind) and global climatic indices. Ultimately, changes in the seasonal patterns of these lower trophic levels will provide insight into their influence on the growth, survival, and overall return strength of salmon populations in the region.
