Research

I am a PhD candidate studying machine learning at the University of Massachusetts Amherst. I work as a research assistant in the Autonomous Learning Laboratory, and my advisors are Sridhar Mahadevan and M. Darby Dyar.

My current research areas include transfer learning, manifold learning, and spectroscopy/chemometrics.

nasa_logo I am a member of the Mars Science Laboratory team, and I work with Prof. Dyar's group on the Mars rover Curiosity. Specifically, I work on the ChemCam instrument, a laser spectrometer (LIBS) that sits on the top of Curiosity. It lases Martian rocks and predicts their chemical compositions. I am working on a few different problems, but the overall goal of my research is to improve the accuracy of the chemical analyses.
