Introduction

I am a Ph.D. candidate at in the Department of Aeronautical and Astronautical Engineering at MIT and a MIT Lincoln Scholar.  I am advised by Prof. Richard Linares in ARCLab and SSL. 

I've worked at MIT Lincoln Laboratory in the Space Systems Analysis and Test group (Group 95) for several years.  My B.S. is in Electrical Engineering and Computer Science at MIT (2010) and a M.Eng in the same department (2012)
