Dr. Susanna Theroux
Dr. Susanna Theroux is an ecologist specializing in microbiology and bioassessment, specifically the interactions between microbial communities and nutrient stressors. She specializes in the use of high-throughput DNA sequencing to untangle microbial interactions, from nutrient food webs and carbon cycling to novel species characterization. Her research focuses on the development of molecular methods (next-generation DNA and RNA sequencing) for bioassessment, with a special focus on microbial community response to anthropogenic disturbance and the use of algal assemblages as indicators of environmental degradation. She has worked in a range of aquatic systems with a special focus on photosynthetic microalgae as sentinels of anthropogenic disturbance and climate change
She received her B.A. in biology and geology from Williams College in 2005, and M.S. and Ph.D. in geological sciences from Brown University in 2009 and 2012, respectively. She joined SCCWRP in 2016.
