Steven M. ShortAssociate Professor / Interim Vice-Principal Research Biology
Broadly speaking, my research focuses on the molecular ecology of aquatic microorganisms. As the major primary producers in freshwater and marine ecosystems, phytoplankton are key components of aquatic food webs and global biogeochemical cycles. Viruses are now known to be abundant in all aquatic environments and many parasitize phytoplankton suggesting that they are important agents of phytoplankton mortality and are themselves key players in aquatic food webs. Hence, my research focuses on understanding the role of viruses in phytoplankton ecology. To that end, I use quantitative molecular techniques to examine virus and phytoplankton community and population dynamics in both natural environments and laboratory cultures.
Students interested in microbial ecology and aquatic microbiology research should contact me directly to discuss opportunities for graduate studies in my lab.
