  • Human Biological Inputs Naomi Miller
    • Gauging environments for biological effects: How do we measure and report light exposure? The lighting research and practice communities are still wrestling with how to evaluate spaces for biological effect. What tools should we use to measure and communicate the light spectrum, duration, and dose? How are those translated into a daily light exposure, and what metrics are appropriate? This talk will introduce the melanopic EDI and melanopic DER metrics proposed by the CIE.
  • Lighting Regulation of Human Circadian Dr. George Brainard
    • Signals transmitted from the intrinsically photosensitive retinal ganglion cells (ipRGCs) reach numerous nuclei and regions in the brain, ultimately having an impact on the peripheral physiology of the body. Accurate measurement of biological and behavioral characteristics such as circadian phase, sleep duration, melatonin secretion, alertness, and numerous other physiological responses is important to understanding how light ultimately impacts human health. This talk will introduce strengths and limitations of some of these biological and behavioral measures in laboratory and field studies.
  • What does Light Quality mean to a Neuroscientist? Doug Steel 
    • Neuroscience and Engineering share a common problem when it comes to characterizing Light Quality; while mathematics allows quantification of tangible properties, the field quickly becomes "squishy" and intangible because of hidden, unknown, or emergent properties. Thus we are left saying "I don't know how to measure it, but I know it when I see it." In this talk we will explore how Systems Neuroscience is bringing understanding to the properties of light that shape our experiences in health and disease.
  • Evaluating Sleep and Behavior Connie Samla
    • Over the past five years SMUD has worked on several lighting projects focusing on sleep and behaviors but utilizing different methods of evaluation. Each successful project had commonalities such as administrative and technical champions, participant education as well as staff dedication. Focusing on sleep for seniors demonstrated positive outcomes with fewer nighttime sleep disturbances while children with autism had noticeable improvements in sleep, behaviors and transitions.

Naomi Miller

Senior Lighting Engineer

Pacific Northwest National Lab

Ms. Naomi Miller is a designer/scientist in the solid-state lighting program at Pacific Northwest National Laboratory in Portland OR. Working to bridge the gap between technology and application, Miller promotes the wise use of LEDs, and works with industry to overcome the hurdles where LEDs are not ready for prime time. Miller has received over 30 architectural lighting design awards for projects ranging from churches to university science buildings, boutique hotels, supermarkets, and parking lots. She chaired the IES Quality of the Visual Environment committee for 8 years and was a principal member of the writing team for Light + Design: A Guide to Designing Quality Lighting for People and Buildings (DG-18-08). She is a Fellow of the IES and Fellow of the IALD.

George C. Brainard

George C. Brainard has directed Jefferson's Light Research Program since 1984. This program's research studies the effects of light on neuroendocrine physiology and circadian regulation in humans. Using the techniques of photobiology, radioimmunoassay, and performance testing, this group has documented how various visible and nonvisible light sources influence both hormonal balance and behavior. Current studies include elucidating the action spectrum of melatonin regulation, investigating the phase shifting capacities of light, studying the influence of light on tumor progression, and testing new light treatment devices for winter depression.

Douglas Steel, PhD

Douglas Steel, PhD is the Founder of NeuroSense ( A Translational Scientist, for the past several years he has been working on the development of applications of spectrally-tunable LED arrays as an alternative to prescription drugs for the treatment of neurological and psychiatric conditions.

He is also a serial entrepreneur, having founded or co-founded and managed 6 technology start-up companies over the past 17 years in a number of life science areas. For several years he was an Entrepreneur-in-Residence at the University of Utah.

Doug has over 30 years of experience in pharmaceutical drug design and discovery, and research project management and implementation divided between academia and the pharmaceutical industry. He has received training in medical sciences and neuroscience, basic and applied biotechnology, integrative neuroscience, and brain-environment interactions. He is the author of over 20 publications in scientific journals and books in the areas of drug design, drug discovery, and marine biochemistry. He has also written over 30 technology articles in the popular press.

Doug holds an M.Phil. and PhD in Biomedical Sciences from Columbia University, an MS (Psychobiology, Univ. of Florida), and a BA (Biology/Chemistry, Kalamazoo College). He also held pharmaceutical research positions at The Upjohn Company, CIBA-Geigy, and Syntex Pharmaceuticals.

Doug is a member of the Science Advisory Panel of the IES (Illuminating Engineering Society), and also serves on the Science Advisory Boards of the Midwest Lighting Institute and the LESA Center at RPI (Lighting Enabled Systems and Applications).

Connie Samla

Connie Samla is SMUD’s Lighting Specialist who is a resource in lighting design for commercial, residential, and industrial customers with over twenty-five years of experience. At SMUD, Connie teaches and coordinates workshops, works on R&D projects and has taught lighting design classes at California State University Sacramento. Connie has a Bachelor of Science in Architectural Engineering from the University of Kansas, a Bachelor of Arts in Ministerial Studies, is a registered electrical engineer, past president of the local IES section, and is lighting certified.
