Dr. Yixin Chen, Professor, joined the faculty in 2006 after three years on the faculty of the University of New Orleans. He has a PhD in computer science from Pennsylvania State University and a PhD in electrical engineering from the University of Wyoming.

Yixin came to University of Mississippi in August 2006 as a displaced New Orleans resident after Hurricane Katrina. He was an Assistant Professor of CS at University of New Orleans from 2003 to 2006.

The School of Engineering named Dr. Chen its Outstanding Faculty Member in 2012.

While on sabbatical, Yixin was a Visiting Scientist at St. Jude Children’s Research Hospital from June 2013-December 2013. He established a valuable collaboration with the Department of Computational Biology during that time.

Professional Research

Chen’s research focuses on the design, analysis, implementation, and applications of machine learning algorithms. He is especially interested in the exploratory and confirmatory analysis of data generated by real-world problems. He has worked on various projects on brain-computer interfaces, knowledge discovery in taxonomic research, content-based image retrieval, automatic image annotation, and control
of robotic manipulators. Chen is serving as an Associate Editor of the journal Pattern Recognition. A complete list of Dr. Chen’s publications and research can be found here.

At the graduate level, Chen teaches courses on algorithm analysis, machine learning, image processing, computer vision, artificial intelligence, mobile robotics, and randomized algorithms.
