Abinesh Ramakrishnan

I am currently a Researcher at Huawei Innovations. I received my PhD (2015) and MS (2010) degrees in Electrical Engineering at University of California, Irvine, supervised by Prof. Athina Markopoulou and Prof. Syed Jafar and my Bachelor's degree from Madras Institute of Technology in 2008. I have also interned at Futurewei Technologies, Inc. (Huawei US R&D Center) in the Fall of 2013, under the supervision of Dr. Cedric Westphal.

Research Interests

My research interest encompasses information theory, network coding, cooperative communication and networking, interference alignment, index coding and content delivery networks.
