Bio: I have had the opportunity to be a part of many diverse research experiences in environmental microbiology ranging from studying microbial communities of remote Appalachian streams, investigating the gut microbiome of Brook Trout, to elucidating the presence and community dynamics of deep terrestrial microbes of fracking wells. Through these experiences I have been motivated by the dearth of understanding and corresponding need to determine how microbes contribute to ecosystem processes. In the Bell lab I am currently working on developing new methods for manipulating microbiomes. I hope to reveal how such manipulations might alter community structure and function and in turn impact ecosystem processes. Accordingly, I am excited to use innovative tools in my research such as various ‘omics techniques to study these dynamics and I look forward to continuing to learn and apply new approaches to tease apart challenging questions.
