Suren Byna

I am a Research Scientist in the Scientific Data Management Group at Lawrence Berkeley National Lab (LBNL). My research interests are in computer architecture and parallel computing. More specifically, I am interested in optimizing data access performance for parallel computing and in utilizing heterogeneous computing power. I am also interested in energy efficient parallel computing.

Before joining LBNL, I was a researcher at NEC Labs America, where I was a part of Computer Systems Architecture Department and was involved in Heterogeneous Cluster Computing project. Even before that, I was a Research Assistant Professor in the Department of Computer Science at Illinois Institute of Technology (IIT). I was also a Guest Researcher at the Math. and Computer Science division of the Argonne National Laboratory and a Faculty Member of the Scalable Computing Software Laboratory at IIT. I received my bachelor's degree in Electronics and Telecommunication Engineering from Jawaharlal Nehru Tech Univ. (JNTU), Anantapur, India and completed my MS in Computer Science, and Ph.D. in Computer Science in Spring 2001 and Fall 2006, respectively, from Illinois Institute of Technology, Chicago.
