Research Interests:

I am interested in how magnetic signatures are recorded within ocean floor sediments.  My PhD research uses materials collected from IODP Expedition 341 from the Gulf of Alaska.  One of my goals is to generate depth to depth stratigraphic relations from a network of drill cores using their magnetic signatures to yield a single age-depth profile.


Other Interests:

I have spent the last 12 years working in the education field and enjoy participating and fostering educational outreach.  I also enjoy cooking, playing board games, and, when time allows, playing video games.
