Project: Mineralogy of Corals Under Climate Change

I am interested in mineralogy, especially biomineralization and how it can be used for environmental purposes and/or nanotechnology. Supported by an NSF GRF, I’m exploring the metal composition of shallow corals and structure of deep-sea corals under various anthropogenic stressors. I have previously worked on high pressure carbonates, biogenic Mn-oxide formation by fungi, coal fly ash and micro- and nano- copper inclusions in gem-quality feldspar.

I enjoy trying to disentangle the biotic and abiotic reaction networks that are involved in biogeochemical cycles and mineralization. I have become increasingly intrigued with identifying and tracking reactive intermediates, in particular short-lived inorganic metabolites that, despite their deceptively low concentrations, have a disproportionately large influence on marine chemistry.

Project: Fungal Induced Chromium Transformations

My research focuses on the interactions between microbes (bacteria and fungi), clay minerals, heavy metals (e.g. chromium and manganese), and organic matter. I am specifically exploring the mechanisms of microbially mediated chromium redox cycling and their potential role in the remediation of heavy-metal contaminated environments.
