Clara Chan

Assistant Professor

I study geomicrobiology, in particular the interactions between microbes and minerals. My research focuses on microbial mineralization, including characterizing mineral phase, morphology, and reactivity, as well as investigating the roles microbes play in precipitation and crystallization processes. I take a multidisciplinary approach, combining geochemical field characterization and sampling, molecular biology, biochemistry, culturing and a wide variety of microscopy and spectroscopy techniques.
