Susanne Kraemer
Postdoctoral fellow

Research interests: I'm interested in how environmental factors shape the biogeography and fitness landscape of natural microbial populations in ecosystems ranging from soil to lakes and the arctic ocean.

David Colatriano
PhD student

Research interests: My work focuses on the microbial community structure and metabolism of the Canadian Arctic Ocean. In particular, I am exploring links between these communities and their roles in biogeochemical cycling.

Arthi Ramachandran
PhD student

Research interests: My research focuses on the metabolic diversity and evolution of methylotrophic bacteria in northern aquatic ecosystems and how they contribute to carbon cycling in freshwater and marine environments in a changing world. I'm also interested in habitat transitions between freshwater and marine environments, and plan to use the OM43/LD28 clade of methylotrophic bacteria as a model organism to study these evolutionary events

Patricia Tran
MSc student

Research Interests: Using metagenomics and metatranscriptomics, I investigate the community structure and metabolism of bacteria in temperate and boreal ice-covered freshwater lakes, specifically in terms of their ecology and role in degradation of organic carbon in these spatially and temporally dynamic environments.

Stephanie Pacheco
MSc student

Research Interests: I am interested in deciphering the ecological roles and the evolutionary relationships of microorganisms in freshwater and marine ecosystems. I am investigating the metabolic activities and biogeography of microbial communities in both the Arctic Ocean and seasonally ice-covered lakes in eastern Canada. In addition, I am exploring the evolution of freshwater-marine transitions through the study of typically freshwater Actinobacteria  clades that we find in marine ecosystems.
