Research Interests
Key words: multi-omics, secondary metabolism, N cycling, natural product discovery
Overview: I am an environmental microbiologist who uses ‘multi-omic’ approaches to understand the biosynthesis of secondary metabolites by cyanobacteria in their native environments, with special interest in Harmful Algal Blooms. I am interested in the role of biogeochemical cycling and microbial interactions in microbial ecology as it pertains to secondary metabolism and chemical interactions between microorganisms. My work uses metagenomic, metatranscriptomic, and metabolomic approaches to link organism, gene cluster, and compound to better understand which organisms are producing which compounds and why in natural communities.
