About Me

Hao Zheng is a tenure-track assistant professor in the Department of Electrical and Computer Engineering at the University of Central Florida. 

Hao Zheng received his Ph.D. degree from George Washington University, advised by Prof. Ahmed Louri. He received his B.S. in Electrical Engineering from Beijing Jiaotong University, China. His research interests are in the areas of computer architecture, with emphasis on on-chip interconnects, energy-efficient many-core architecture designs, and machine learning for efficient computing.


Graduate Research Assistantships (GRAs) are available for Ph.D. students to work on several research projects include, but not limited to: machine learning techniques for efficient computing; heterogeneous chiplet-based architectures; application-aware reconfigurable manycore architectures; graph processing and neural network accelerators. 

I am also hiring master and undergraduate research assistants at UCF.
