RIS Corp. was founded in 1992 to bring advanced environmental monitoring technologies from the research lab to the marketplace. RIS Corp. designs and manufactures electronics and detector systems for the physics research and environmental survey communities. A complementary team of technical and business professionals manage company operations with over 200 years of design development, engineering and marketing experience.

President Richard Todd, Ph.D,. is an electronic design engineer and President of RIS Corporation. His education includes a Ph.D. in Electrical Engineering from the University of Tennessee, Knoxville. His main interest is in the area of analog and digital circuit design (both discrete and monolithic) with particular emphasis on nuclear radiation detection. He has authored and/or co-authored over 30 papers in the area of instrumentation and circuit design and has designed over 25 integrated circuit chips including dielectrically-isolated bipolar, CMOS, and gallium-arsenide (GaAs) technologies. He holds four patents, an IR-100 award, and received a Martin Marietta Energy Systems Inventor Award while at Oak Ridge National Laboratory. He has designed several successful instruments based on pulse shape discrimination circuitry as well as a line of electronics for silicon strip detectors. Richard served on the Fairview Technology Center Advisory Board in Knox County from 2002 - 2007 and currently serves on the Industrial Advisory Board for the EECS Department in the College of Engineering at the University of Tennessee in Knoxville.

Design Engineer Adam Miller joined RIS Corp. in 2006 with a Master's Degree in EE from The University of Tennessee at Knoxville. Adam's expertise is in the field of digital logic design and his background includes the development of sophisticated encryption algorithms as a project researcher after his graduaton. His research and design at RIS include FPGA implementation of digital signal processing algorithms for applications involving neutron-gamma discrimination, portable multi-channel analyzer (MCA) use for hold-up monitors, and for silicon strip electronics to determine energy and position in resistive strip applications. Adam has recently participated in taking one of his microcontroller-based instruments through FDA certification for a medical application. Adam and his wife Lara are parents to three young boys and their interests include camping and Medieval literature.

Joe Research Technician Joe Mode joined our production staff in November 1997. He has a B.A. in Anthropology as well as a B.S. in Broad Field Social Studies, both from the University of Tennessee at Knoxville, 1985 and 1988, respectively. He has extensive experience in both production and prototype assembly and performs functional tests on products. Joe has been inducted into the Southern Highland Craft Guild in recognition of his treenware wood carving craft, and he is an active Civil War buff. Joe was cast in the filming of the blockbuster movie Gods and Generals as well as an A&E special about the film Cold Mountain.

Brian Brian Winton graduated in March 2006 from ITT Technical Institute in Knoxville with a major in Electronics and Communications Engineering Technology. Previously he attained his Certified Electronic Technician (ICET) - Associate Level, and graduated in August 2002 from Tennessee Institute of Electronics in Knoxville, Tennessee with a Specialized Associate Degree in Electronic Technology. Brian uses his technical skills in the assembly and testing of circuit boards and instrumentation as part of the RIS manufacturing team. In his spare time, Brian likes to cook and casseroles are his specialty!

Gary Gary Armstrong is a contract employee with RIS Corp. through Maverick Systems, Inc., a company that specializes in robotics, robotic vision, and custom embedded systems. Gary received his B.S. in Electrical Engineering from Tennessee Technological University, Cookeville, Tennessee, in 1981 and an M.S. in Electrical Engineering at the University of Tennessee, Knoxville, in 1989. He is a registered Professional Engineer in the State of Tennessee and has 20+ years of experience as an R&D engineer in the Robotics and Process Systems Division at ORNL where he obtained a patent for a robotic tracking system technology. Gary is proficient in the development of control and communications systems requiring real-time software, embedded micro-controllers, and digital state machines (discrete TTL logic, FPGAs, and custom VLSI). He is a member of IEEE, SPIE, Tau Beta Pi, Eta Kappa Nu, Omicron Kappa Delta, and Phi Kappa Phi, and has served as chairman of the East Tennessee/Oak Ridge IEEE Chapter of the Computer Society. He has written several LabView programs for RIS projects and is currently involved in production testing of the RIS DataBit used for downhole monitoring and logging applications.

Rainer Rainer Riffert provides printed circuit board layout and mechanical packaging services to RIS Corp. Rainer received his B.S. degree in Electrical Engineering from The University of Tennessee and is a member of the East Tennessee Inventor's Forum. He is proficient in surface mount design and packaging and has developed several consumer audio and rf products used with the Apple iPod.
