Research and Teaching Interests
I use a combination of multi-element redox
proxies and isotopic techniques to understand modern biogeochemical processes
as a key to deciphering biological signatures recorded in the sedimentary record. My goal is to pair my
scientific interests with teaching students by introducing them to active
research in an academic environment.
