I am currently a Postdoctoral Scholar at Caltech in Prof. Babak Hassibi's group. From September 2015 I will be a postdoc at the University of Washington in Prof. Maryam Fazel's group. In June 2015 I completed my PhD in EECS at MIT. My advisors were Prof. Pablo Parrilo and Prof. Alan Willsky. In 2008 I received the Bachelor of Science degree in mathematics and the Bachelor of Engineering degree in electrical engineering from the University of Melbourne. I spent the first half of 2009 as a volunteer teacher at Divundu Combined School in beautiful Divundu, Namibia. |
