VMware is very pleased to award the first two VMware Graduate Fellowships, for the 2012/2013 academic year, to Dongyoon Lee, University of Michigan, and Robert Escriva, Cornell University.
Dongyoon Lee’s research interests are in improving the programmability of parallel computer systems. Unlike sequential processors, a multiprocessor system is not guaranteed to produce the same result even when a program is executed over exactly the same input, which causes significant issues in debugging and fault tolerance. Dongyoon’s research has produced ultra-low overhead software and hardware deterministic replay systems by leveraging complementary strengths of static program analysis, the operating system, and computer architecture.
Dongyoon received the B.S. degree from Seoul National University, Seoul, Korea, in 2004 and the M.S degree from the University of Michigan, Ann Arbor, MI, in 2009. He is now a PhD candidate in the EECS department at the University of Michigan, where he works with Prof. Satish Narayanasamy as a member of the Advanced Computer Architecture Laboratory (ACAL) and Software Systems Laboratory (SSL) research groups.
Robert Escriva’s research focuses on building and understanding large-scale infrastructure services for web applications. His current research project is HyperDex, a high performance searchable key-value store which provides strong guarantees while achieving high performance. HyperDex strategically places objects on servers so that both search and key-based operations contact a small subset of all servers in the system. Unlike typical key-value stores, HyperDex takes into account all attributes of an object when mapping it to servers. HyperDex’s novel object placement and replication strategies support efficient search, providing high throughput and low latency with linear scaling.
Robert graduated in 2010 from Rensselaer Polytechnic Institute with a B.S. in Computer Science. In the fall of 2010, he joined the Ph.D. program in Computer Science at Cornell University where he works in Emin Gun Sirer’s research group.
