From August 2013 to November 2014, I was a Postdoctoral Associate with Bill Freeman at MIT’s CSAIL Lab. In June 2013, I received my PhD from the Computer Science department at New York University , under the supervision of Rob Fergus. I was awarded a Microsoft Research PhD Fellowship for 2010-2011, a Dean’s Dissertation Fellowship for 2012-2013 from the Graduate School of Arts and Sciences and the Janet Fabri prize (2013-2014) for outstanding dissertation in Computer Science.
