PROFESSIONAL EXPERIENCE:

 

Dr. Engel is an Associate Professor in the Department of Electrical and Computer Engineering, Southern Illinois University Edwardsville (SIUE), where he teaches courses in computer engineering, electronics, senior design, and integrated circuit technology.  He joined the faculty in 1993. Dr. Engel's primary research interest has been, and still is, in the design of high performance analog circuits.

 

From January 2000, Dr. Engel has been working with a team of researchers at Washington University on the development of a mutichannel integrated circuit for use in colliding particle experiments. Also, since 1994, he has collaborated with researchers at Washington University in Saint Louis and Magtek, Inc, in Carson, CA to develop a method for authenticating magnetic media.  The primary objective of the project is the development of a reliable method of authenticating and verifying credit cards using magnetic fingerprinting.  The Magneprint TM technology, however, may also be applied to objects bearing magnetic ink such as checks or other paper documents and also to objects to which a magnetic material can be affixed or embedded.

 

From 1998 to 2000, he worked with Dr. T.K. Parthasarathy from the Department of Communication Disorders, Southern Illinois University at Edwardsville, and researchers at Everest Biomedical Instruments Corporation.  The objective of the project was the development of portable instruments that would enable audiologists to more effectively screen infants for hearing impairments.  Early in 2002, VIASYS Healthcare signed an exclusive worldwide license agreement to sell, the AUDIOscreener TM, considered by many to be the most advanced technology in the world today.  In addition to his work with Everest Biomedical, he is also working with another St. Louis based company, BECS Inc., on the development of an integrated circuit capable of measuring fluid levels for use in a wide variety of commercial applications, including washing machines and automobiles.

 

From May 1991 through May 1993, he was involved in a wide range of endeavors.  In addition to teaching courses in the design of analog integrated circuits and digital systems at Washington University, he conducted research in the area of low-power digital hearing aid technology and served as a consultant, designing circuits for use in ultrasonic imaging systems, electric utility monitors, and magnetic disk drives.  During this period he also co-founded LoCAT, Inc., a St. Louis based company that specialized in computer-assisted tracking systems where he worked in the area of RF receiver design.

 

From August 1985 through May 1991 he was involved in the research and development of a digital hearing aid.  His early work centered on the development of digital signal processing software for a multi-processor system used to perform real-time simulations of a digital hearing aid.  Later, he designed low-power integrated circuits intended for use in digital hearing aids. His dissertation, "Analysis and Design of Logarithmic Digital Quantizers With Applications to Low-Power Data Interfaces for Speech Processing", addressed both theoretical and practical issues concerning the design of data converters employing sign/logarithm encoding. 

 

Dr. Engel is an active member of the IEEE and has served for over 7 years as both a branch counselor for the SIUE IEEE student branch and as the student activities chair for the St. Louis Section of the IEEE.
