Expertise
Dr. Steven is an environmental microbiologist with expertise
in soil and aquatic environments. His research interests are to better
understand how microbial populations respond and contribute to various climate
change scenarios. Professional experience includes classical and molecular
microbiology, metagenomics, metatranscriptomics, and bioinformatics.
Past Research
Dr. Steven’s research career has involved studying the
microbial communities in Canadian high Arctic permafrost, freshwater algal
blooms, and biological soil crusts of the Southwest U.S.A.
Current Research
Microbial communities are exquisitely sensitive to small
perturbations in the environment. The ability to predict how microbes respond
and contribute to important climate and biogeochemical cycles is required for
accurate ecosystem models. Dr. Steven’s work focuses on using molecular and
microbial techniques to better describe complex microbial systems. Current
systems of interest include Connecticut and Arctic wetlands, harmful algal
blooms in Connecticut lakes, and wood-degrading bacterial/fungal
communities.
