Highly-motivated PhD students are sought to start in Spring/Fall 2017 under Professor Dong Li in the areas of high performance computing, and parallel and distributed systems. Funding for students is expected to be in the form of research and/or teaching assistantships. 

Dr. Dong Li is an assistant professor in the Department of Electrical Engineering and Computer Science, University of California, Merced since 2015. He is the director of Parallel Architecture, System, and Algorithm Lab (PASA). Previously (2011-2014), he was a research scientist at the Oak Ridge National Laboratory (ORNL). Before that, he earned his PhD in computer science from Virginia Tech. Dong received a CAREER Award from U.S. National Science Foundation in 2016, and an ORNL/CSMD Distinguished Contributor Award (2013). His paper in SC'14 was nominated as the best student paper.

Dong's research focuses on high performance computing (HPC), and maintains a strong relevance to computer systems. The core theme of his research is to study how to enable scalable and efficient execution of enterprise and scientific applications on increasingly complex large-scale parallel systems. His work creates innovation in runtime, architecture, performance modeling, and programming models; His work often coordinates software and hardware to solve resilience and power challenges. He also investigates the impact of novel architectures (e.g., non-volatile memory and accelerator with massive parallelism) on the designs of applications and runtime. Dong's approach to research has always been application-driven. He believes measuring and understanding characteristics of realistic large-scale parallel applications is critical to identify problems, provoke thought and prevent fundamental design flaws.

In collaboration with industry, DOE laboratories, and universities, Dong has been involved in various DOE, DOD and NSF projects related to HPC. His work was published in a number of premier HPC conferences. He is a program committee member in a number of international conferences and workshops.
