Zhen Peng
Hi there. I am a Postdoctoral Researcher at Pacific Northwest National Laboratory (PNNL). My mentor is Dr. Gokcen Kestor. I received my Ph.D. from the Department of Computer Science at William & Mary under the supervision of Dr. Bin Ren.
My research interests lie in parallel computing with an emphasis on the design and optimization of parallel solutions for sparse computations and graph-based applications, relevant areas including:
- Parallel Computing
- High Performance Computing
- Compilers
- Machine Learning Optimization
Before joining William & Mary, I received my bachelor’s and master’s degrees in the Department of Computer Science at Huaqiao University, China in 2013 and 2016, respectively. My master’s research advisor is Dr. Tian Wang.
