Research Scientist

Leads and conducts research linking marine biotoxins and trace metals to ocean ecology and climate change.

Current research and/or projects

Dr. Andrew R.S. Ross is a Research Scientist at the DFO Institute of Ocean Sciences in Sidney, British Columbia. He develops and uses analytical methods to study biological and environmental processes that control the availability and distribution of trace elements, marine biotoxins and contaminants. His research involves profiling essential trace metals (micronutrients) and metal-binding compounds (ligands) in the ocean and developing mass spectrometry (MS)-based methods to detect and quantify toxic chemicals in the marine environment. He conducts his research in collaboration with colleagues at universities and other government laboratories in Canada and internationally.

Research and/or project statements

Dr. Ross is DFO Lead Scientist for the Line-P Iron Program, a GEOTRACES process study. He is currently Principal Investigator on an ACRDP project to study links between environmental conditions and the impacts of harmful algae and associated biotoxins on BC salmon farms, in collaboration with aquaculture industry partners. His research supports the provision of science advice regarding the potential impacts of climate change and other stressors on marine fisheries and ecosystems due to their effects on biotoxin, contaminant and micronutrient levels. Dr. Ross is an Adjunct Assistant Professor in Biochemistry and Microbiology at the University of Victoria, British Columbia where he teaches and supervises graduate and undergraduate students in marine biogeochemistry and proteomics. He is a member of the IOC International Group for Marine Ecological Time Series.
