Research Interests

Marina Gemma is a PhD Candidate at Columbia University and the Lamont-Doherty Earth Observatory who does her research in the Department of Earth and Planetary Sciences at the American Museum of Natural History. She studies primitive meteorites with Denton S. Ebel, focusing on the spectral and geochemical characteristics of ordinary and carbonaceous chondrites using a variety of analytical techniques. She greatly enjoys teaching, mentoring undergraduate researchers, and the multitude of public outreach she does as a scientist at AMNH and in New York City.
