Matt Harke, PhDResearch Scientist I
Matt Harke comes to GMGI with broad interests in molecular and aquatic microbial ecology. Before joining GMGI, he was an Associate Research Scientist at Columbia University’s Lamont-Doherty Earth Observatory where he used metatranscriptomics to characterize the distribution, composition, and function of microorganisms in situ and in response to physical and chemical changes. He completed his MS and PhD at Stony Brook University investigating a range of topics including harmful algal bloom ecology (both fresh and marine), benthic-pelagic coupling, and microbial ecology.

Microbes have played critical roles in shaping the biosphere since their evolution almost 3.5 billion years ago. The Earth harbors an estimated 1030 microbial cells, and we are still challenged with understanding the full extent of their diversity and function. Microbes are recognized to have fundamental roles in global biogeochemical cycles, are critical to host well-being, and are involved in the evolution of plants and animals. Anthropogenic changes to the biosphere have led to shifting dominance of microbes and in some cases have caused deleterious ecosystem effects such as harmful algal blooms. As such, understanding how microbes interact with the environment and how the environment shapes microbial structure has been an important research topic for decades. As an aquatic microbiologist, a central theme of my research is to understand the genetic underpinnings that drive the proliferation of microbes in response to changing conditions in both marine and freshwater ecosystems. My research crosses trophic boundaries, from nutrient poor oligotrophic waters to eutrophic coastal estuaries and freshwater lakes, investigating the causative drivers of microbial diversity, occurrence, function and toxicity.
