Germicidal Ultraviolet Opportunities for Lighting Experts

Dr. David H. Sliney, Ph.D., serves as chair of the IES Photobiology Committee and holds a Ph.D. in biophysics and medical physics from the University of London, Institute of Ophthalmology. He worked for the US Army Public Health Center until retiring in 2007. His research interests focus on UV effects upon the eye, optical hazards from intense light sources and lasers, laser-tissue interactions and laser applications in medicine and surgery. He served as member, advisor and chairman of numerous committees active in the establishment of safety standards for protection against non-ionizing radiation (ANSI, ISO, ACGIH, IEC, WHO, NCRP, and ICNIRP).

Richard Vincent is the Manager, the Brickner Research Unit on Community Medicine and TB/UV Studies at the Icahn School of Medicine at Mt Sinai Hospital in New York. He is a leader in the refinement of upper-room germicidal UV for control of infectious disease, such as tuberculosis. He has been a consultant to many healthcare facilities in providing guidance on efficacy of germicidal ultraviolet and spoken throughout the world on this technology. He has long been active in the IES Photobiology Committee and is currently the chair of an ASHRAE Committee preparing guidance on Upper Room germicidal UV. Further he chairs the CIE TC 6-52 on the gonioradiometric measurement of UVGI luminaires.

Andrew ("Andy") Jackson has been with Signify North America Corporation and Philips Lighting for over 25 years and started his career as a development engineer for High Intensity Discharge (HID) lighting. Mr. Jackson has 11 patents and several proprietary awards related to various lighting products. He is currently the manager of the Signify Lighting Test Center – Americas (LTCAm). This laboratory has responsibilities for the testing and regulatory aspects of all Signify products sold in the Americas. The laboratory is National Voluntary Laboratory Accreditation Program (NVLAP) accredited and Canadian Standards Association (CSA) certified for measurements related to lighting energy efficiency verification.

Mr. Jackson has long been an active member of the IES Photobiology Committee and is a key member of the Council for Optical Radiation Measurements (CORM). He is heavily involved with the American National Standards Institute (ANSI) activities related to standardization for lighting products and with the Illuminating Engineering Society of North America (IESNA) for light measurement methodologies and recommended practices. Mr. Jackson is active with the US National Committee (USNC) Technical Advisory Group (TAG) for the International Electrotechnical Commission (IEC). He chairs the ANSI Accredited Standards Committee (ASC) 78 Lamps and is the Vice Chair for the IES Technical Procedures Committee.

Mr. Jackson holds a BSEE and MSEE from Old Dominion University, and an MBA from Kansas Wesleyan University. Mr. Jackson’s MSEE Thesis was sponsored by NASA and was entitled, “Laser Absorption Spectroscopy with Tunable Diode Lasers.”

Prof. Ernest ("Chip") Blatchley is the Lee A. Rieth Professor in Environmental Engineering at Purdue University in West Lafayette, IN. He chaired a task force of the International UV Association (IUVA) in 2020-2021 that prepared a white paper on Far UV-C Radiation. His research interests focus on physico/chemical processes of environmental engineering. His research emphasis is on processes that involve UV radiation, chlorine, or both. His current research foci include disinfection processes for water, UV disinfection of air and surfaces, UV-based advanced oxidation processes, and swimming pool chemistry.
