Research Interests

Dr. Mayali's interest is in the molecular ecology and physiology of microorganisms and how they control carbon and nitrogen biogeochemistry. He applies 'omics and geochemical techniques (the NanoSIMS in particular) to link microbial phylogenetic structure and biogeochemical functions.
