Dr. Travis Longcore is a leading expert in the environmental and ecological effects of night lighting. He consults to lighting engineers and designers and local, state, and federal governments to reduce the adverse consequences of artificial light at night. His landmark article “Ecological Light Pollution” (Longcore and Rich 2004) and 2006 co-edited book Ecological Consequences of Artificial Night Lighting (Island Press) have come to define a new and rapidly growing research area in ecology.
