I am currently a Lecturer in the Department of Electrical and Computer Systems Engineering at Monash University in Melbourne, Australia. In June 2015 I completed my PhD in EECS at MIT. My advisors were Prof. Pablo Parrilo and Prof. Alan Willsky. From June 2015-June 2016 I was a Research Associate (postdoc) at the University of Washington in Prof. Maryam Fazel's group and a Postdoctoral Scholar at Caltech in Prof. Babak Hassibi's group. |
