I am currently a Research Associate (postdoc) in Prof. Maryam Fazel's group in the Department of Electrical Engineering at the University of Washington. From July 2016 I will be 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 until September 2015 I was a Postdoctoral Scholar at Caltech in Prof. Babak Hassibi's group. 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. |
