Hansheng Lei received his B.S. from Ocean University of China in 1998 and M.S. from University of Science and Technology of China in 2001, both in computer science. He finished his Ph.D. study in the Department of Computer Science and Engineering, University at Buffalo, the State University of New York in December 2005. He joined the Computer and Information Sciences Department at the University of Texas at Brownsville (UTB) as an assistant professor in Jan 2006. He is promoted to Associate Professor with tenure Fall 2012 and to Professor Fall 2018. His current research interests lie in distributed machine learning, computer vision and data mining in a High Performance Computing (HPC) environment. He has published over thirty articles in peer-reviewed conferences/journals. He has completed several projects funded by NSF and US Department of Education with a total amount of $3.5M. He has served as a proposal reviewer for a variety of funding agencies, including NSF, Department of Education and Department of Commerce.
