Research Interests

Research in the Hansel lab sits at the intersection of mineralogy, geochemistry, and microbiology with the goal of disentangling the reaction networks responsible for mineral formation and dissolution. We are interested in how mineral dynamics are constrained by microbial activity, how minerals contribute to microbial evolution, and whether minerals harbor short- and/or long-term signatures of life. To explore these systems, we use a combination of geochemical and microbiological approaches, including synchrotron-based X-ray absorption spectroscopy and scanning transmission X-ray microscopy, in situ imaging mass spectrometry, and high-resolution electron microscopy.
