John Bullough, PhD, is a program director at the LHRC.  Dr. Bullough conducts research in a wide range of areas related including human factors, transportation lighting, and lighting for safety.  He has conducted numerous studies looking at the quantification and prediction of glare from both interior and exterior lighting systems and is the author of the recent book Understanding Glare in Exterior Lighting, Display, and Related Applications, published by the International Society for Optics and Photonics (SPIE).

Mariana Figueiro, PhD, is among the world’s leading experts in the area of light and health, with a focus on bridging science to practical applications aimed at improving human quality of life. She has made a significant impact on this developing field and continues to actively expand her influence through translational research and teaching. She is the Director of the Light and Health Research Center and serves as Principal Investigator of various research projects at the Center. She regularly collaborates with lighting designers and manufacturers, through her work with the Center’s Light and Health Partners program. Dr. Figueiro previously served as the Director of the Lighting Research Center at Rensselaer Polytechnic Institute.

Rohan Nagare, PhD, is a research scientist at the Light and Health Research Center. He holds a PhD in Architectural Sciences with a concentration in Lighting from Rensselaer Polytechnic Institute. He currently works on a variety of health-related research projects at the LHRC including work on modeling of the human circadian system, the impact of light on circadian entrainment, as well as other related research.

Mark S. Rea, PhD, is a professor at the Light and Health Research Center and an expert in human vision, lighting engineering, human factors, photobiology, psychology, and light and health. He is the author of more than 100 scientific and technical articles related to vision, lighting engineering, and human factors and was the editor-in-chief of the 8th and 9th editions of the IESNA Lighting Handbook. His current research projects include the study of the effects of light on circadian disruption, lighting to enhance the safety of emergency workers, and the development of a bias-free pulse oximetry device. Dr. Rea has conducted groundbreaking research in the areas of human visual performance, visual efficacy at nighttime light levels, and light and human health. 

Nicholas Skinner, MS, is senior clinical research coordinator at the LHRC. He holds undergraduate degrees in both physics and mechanical engineering and a master of science in lighting. He has worked extensively on the application of ultraviolet energy to mitigate plant pathogens including leading field trials in the use of UV to combat squash powdery mildew, cucumber downy mildew, and fire blight on apple crops. His current work also includes the design of a system to apply UV LED technology to agricultural applications.
