Dr. Keng Deng earned his Ph.D. in Applied Mathematics at Iowa State University in 1990. Upon graduation, he became Assistant Professor of mathematics at the University of Louisiana at Lafayette. In 1995, Dr. Deng was granted tenure and promoted to Associate Professor. He then advanced to Professor in 2001.

Dr. Deng's field of research is Partial Differential Equations with an emphasis on nonlinear problems arising from applied sciences. In this area, over 80 of his research papers have been published in professional journals. As a PI or Co-PI, Dr. Deng has received National Science Foundation grants exceeding $450,000. He has also directed twelve doctoral students.
