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.
