received a B.S. in electrical engineering in 1968 at the National Taiwan University
Ph.D. in computer science/applied mathematics at the Harvard University in 1973
From 1974 to 1978 Chen as Assistant Professor at MIT Sloan School of Management.
From 1978 to 1984 he was Professor at the University of California, Los Angeles (UCLA Management School)
Since 1983 Chen has held the position of M. J. Foster Distinguished Chair Professor of Computer Science at Louisiana State University.
The initial approach to IDEF information modeling (IDEF1) was published by the ICAM program in 1981, based on current research and industry needs. The theoretical roots for this approach stemmed from the early work of Edgar F. Codd on relational theory and Peter Chen on the entity-relationship model. The initial IDEF1 technique was based on the work of Dr. R.R. Brown and Mr. T.L. Ramey of Hughes Aircraft and Mr. D.S. Coleman of D. Appleton & Company, with critical review and influence by Charles Bachman, Peter Chen, Dr. M.A. Melkanoff, and Dr. G.M. Nijssen.
