Paul Raptis

Manager, Detection and Diagnostic Systems Department
- Nuclear Engineering

A. C. (Paul) Raptis is a senior electrical engineer at Argonne National Laboratory with 40 years of experience in teaching and in research and development. He is the department manager for Detection and Diagnostic Systems in Argonne’s Nuclear Engineering Division. His areas of expertise include sensors, instrumentation and controls, nondestructive evaluation, data processing, electromagnetics, plasmas, optics, acoustics and geophysical exploration. He has an extensive background in developing new research programs.

Raptis is responsible for national security research on remote detection of chemical, biological, nuclear agents and explosives. In addition, he has been a strong participant in collaborative work with the University of Chicago in the development of the bioengineering initiative. He has worked with U.S. industries (automotive, chemical, textiles, glass, steel, etc.) on the technology transfer initiative from the U.S. Department of Energy.

At Argonne, Raptis initiated and helped develop Argonne's Instrumentation and Nondestructive Evaluation programs for nuclear and fossil energy, conservation, arms controls and national security. These technologies include optics, microwaves/millimeter waves, acoustics and neutron diffraction.

Raptis has been a member of Argonne and National Laboratories Committees on global warming, space exploration, effluent research (LAGER, a national security committee for NA22) and textiles (American Textile Consortium). He also served on national committees on instrumentation sensor needs and multiphase flow.

Prior to working for Argonne, Raptis worked as a research engineer for Cuf Research and Development Company and joined the laboratory in 1974. He has also been Adjunct Professor at the Electrical Engineering Department, University of Illinois at Chicago, and is currently on the advisory board for the Electrical Engineering Departments of the Universities of Akron and Miami of Ohio. He is the author of more than 250 publications and holder of 17 patents, as well as a recipient of a 1994, 1996 and 2006 R&D 100 Award, and the 1994 American Society for Nondestructive Testing Best Paper Award.
