Research


Cosmochemistry

My primary research interests are in the laboratory analysis and scientific implications of extraterrestrial materials, including meteorites and interplanetary dust particles. I am very interested in presolar grains in meteorites and in the development of new techniques for isotopic analysis and mapping of small samples. I am actively involved in the analysis of cometary samples returned by NASA's STARDUST mission and solar wind samples returned by the GENESIS mission.

Planetary Missions



I also work on X-ray and Gamma-ray spectrometers for planetary missions. NASA's MESSENGER mission is the first spacecraft to visit the planet Mercury since 1975. It flew by the planet 3 times before its successful orbit insertion on March 18, 2011. It has been orbiting he planet for more than two years and is in is second extended mission. I was named Deputy PI of the mission in 2012.
