Dr. Chou, Associate Professor, received a B.S. in Chemical Engineering from the Ming-Chih Institute of Technology in 1984, and an additional B.S. in Computer Science from the National Taiwan University. He went on to receive his Ph.D. in computer Science from the University of Maryland, College Park, MD in 1996. Dr. Chou served as a Lecturer in the Department of Computer Science at the University of Maryland, College Park, from 1996 to 1997. He was also named a Postdoctoral Fellow for The Institute of Genomic Research, Rockville, MD from 1996 to 1998. At that time, he became a Research Scientist for Celera Genomics Corporation in Rockville. Dr. Chou came to Iowa State University in 1999 with a joint appointment in both the Departments of Computer Science, and in Genetics, Development and Cell Biology.

Research Description

My research interest has been the development of sophisticated computer science algorithms for efficiently solving large scale biological research problems, e.g., the automatic DNA sequence clean up programs (LUCY1 & 2), an efficient whole-genome oligo microarray design tool (PICKY), and an automatic Perl programming tool (VECT) for biologists. My software tools employ novel approaches to computing and generally provide better results than previous methods. For example, while most microarray design tools are still based on the sequence level comparison to screen out nontargets, my PICKY program has embedded a complete suite of thermodynamic equations in its calculations to infer the best oligo candidates based on the whole genome, and it does so orders of magnitude faster than any other comparable microarray design tools with the same computation depth. My recent focus is on the whole-genome siRNA design using a similar thermodynamic calculation approach.
