My research involves understanding the impact history of the Earth-Moon system. I study the geochemical and chronological information obtained from lunar impact glasses in order to understand how many impact events the lunar surface has suffered. This information can then be applied to understanding the conditions required for life on Earth and how impact events may have affected its origin and evolution. I’m also interested in understanding how biomolecules are transferred among planetary bodies, such as via comet or asteroid impacts, and how their chemistry may change in an impact event.
I am currently affiliated with the New York Center for Astrobiology, a NASA Astrobiology Institute, and my lunar research is supported by NASA, the NSF, and the American Astronomical Society. My impact research is supported by NASA and the NASA Astrobiology Institute. Both projects have additionally been supported by Albion College faculty development funds.
During Fall 2011, I did research at the Australian National University in Canberra, studying lunar samples with Dr. Marc Norman.
