I am a graduate student in the EECS department at MIT. My advisors are Prof. Pablo Parrilo and Prof. Alan Willsky. I am a member of the Stochastic Systems Group which is a part of the Laboratory for Information and Decision Systems. 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. |
