Enrique del Castillo, Ph.D. is a Professor of Industrial Engineering and Statistics at Penn State University. Dr. Castillo's main interests are in the areas of Engineering Statistics and Quality Engineering, with emphasis in:

• Statistical and Time Series Process Control;
• Experimental Optimization;
• Response Surface methods;
• Applied Bayesian Statistics.

These are areas in which he has published over 60 refereed journal papers. In the last ten years, Dr. Castillo's research has focused on the analysis and design of  process adjustment methods for use in manufacturing, the development of statistical techniques for the rapid experimental optimization of initially unknown, multiple input, multiple response systems, and statistical inference in response surface optimization. Recent work includes development of  Bayesian techniques for these problems. He is a recipient of a National Science Foundation Career Award (1996-2001), an Associate Editor of the Technometrics journal, a member of editorial board of the Journal of Quality Technology, and a past Associate Editor of IIE Transactions.

Since 1995, Dr. Castillo's research has been funded uninterruptedly by the National Science Foundation (NSF). Additional research funding has been provided by the General Motors R&D Corporate Center, Intel Corporation and by NATO. This funded research has totaled over 1 million dollars. At PSU's IME department, Dr. Castillo is director of the Engineering Statistics Laboratory.   He has a joint appointment with Penn State's Department of Statistics.
