Expeditions

*2003: Austral summer season in the Dry Valley Region, Antarctica mapping and sampling silicic segregations in the Ferrar Dolerite Sills, through the United States Antarctic Program.

*2001: Austral summer season in the Dry Valley Region, Antarctica mapping and sampling  the Ferrar Dolerite Sills and the Dais intrusion, through the United States Antarctic Program. 

*1997: Research Assistant at Lamont Doherty Earth Observatory of Columbia University, New York. Worked aboard the RV/ Melville during Panorama Leg 1 to East Pacific Rise to investigate hydrothermal plume signals, using the Miniature Autonomous Plume Recorder (MAPR) to collect nephalometry, temperature and density data in the water column.

*1996: Research Assistant at Woods Hole Oceanographic Institution, Woods Hole MA. Worked aboard the R/V Knorr to the Lucky Strike, Mid Atlantic Ridge to investigate correlations between magnetic anomalies and hydrothermal vent activity using on board magnetometer data.
