Portrait of Dr. Chul-Ho Lee

Biography and expertise

I am currently an Associate Professor in the Department of Computer Science at Texas State University, San Marcos, TX. Prior to joining Texas State, I was an Assistant Professor in the Department of Computer Engineering and Sciences (now the Department of Electrical Engineering and Computer Science) at the Florida Institute of Technology, Melbourne, FL, and a Senior Research Engineer at Samsung Electronics DMC R&D Center (now Samsung Research), South Korea. I received my Ph.D. degree in Computer Engineering from North Carolina State University, Raleigh, NC. My research interests are in network/data science, machine learning, networking, and systems. My recent research focuses on (1) developing efficient algorithms and computational tools for large-scale graph mining and network analysis, and (2) leveraging and advancing machine learning techniques for mobile, IoT and other applications. My research has been supported by funding agencies and industry partners including the National Science Foundation, NVIDIA, and SK Hynix America.
