Nick Falk completed his Master’s degree under the supervision of Dr. Weisener where he focused on microbial-influenced precipitation of zinc sulfide minerals in anoxic environments. His current work at the Great Lakes Institute for Environmental Research (GLIER) involves understanding how microbes work together in the environment to break down and store unwanted contaminants and nutrients. Specifically, he is interested in quantifying gene expression from microbial communities in both natural and laboratory settings as they respond to the stresses associated with agricultural and industrial land use. He hopes to spread the message that, although small in size, these organisms exert a disproportionately large force on the world around them, which extends to fresh water security and the health of the Great Lakes. When he’s not in the lab, Nick is an avid runner, having represented Canada at several international cross country and track and field competitions.
