I am a geologist who specializes in igneous petrology and geochemistry, which means someone who studies rocks that solidified from magma or lava and tries to decipher how these formed.

My research focuses on the origin and distribution of lavas forming large igneous provinces or flood basalts. These eruptions have occurred in many locations on Earth, as well as on other planets, throughout geologic history. The smallest and youngest province is located in the United States. This site covers parts of Washington, Oregon, and Idaho. There are also very large eruptions that cover over 2 million km2, like the Siberia Traps in Russia.

Before I got my PhD, I worked as an environmental consultant, and I am excited about transitioning back to environmental science in my role at Barnard. I'll still be doing my work on volcanoes, which is a little different, but being part of an environmental science department and teaching students about the importance of our environment is a great opportunity to combine these aspects of my work and interests.

I'll be teaching lab courses for Introduction to Environmental Science, and in the spring of 2015, I will be teaching a course related to geology and igneous petrology.
