I am currently a third-year graduate student in the Boston University Department of Astronomy and Institute for Astrophysical Research. My research interests revolve around protoplanetary disks and their evolution. These disks of gas and dust form around young stars as they collapse from molecular clouds. I am particularly interested in the disks around low-mass, T Tauri stars and I want to answer open questions about how these disks evolve into planetary systems and the complexities that come along with that evolution. My work thus far as been the analysis of 180 disks in the star-forming region Lynds 1641 (L1641) which lies in the Orion Molecular Cloud A; this work will be presented soon in an upcoming paper.
