Professor Larry Kalkstein is a bioclimatologist who specializes in the impact of weather on human health.  He has been conducting research in applied climatology for many years, and has dealt with problems such as weather’s impact on heat-related illnesses, understanding how reflective roofing and paving materials can significantly alter summer heat and health problems, and many other issues.  

Dr. Kalkstein has served as principal investigator on many projects dealing with the development of heat/health warning systems for major cities worldwide. He has also been involved in the development of numerous weather indices for use in applied climatological research; these are now used worldwide.

Dr. Kalkstein’s most recent contracts include collaborations with the 3M Corporation, to determine how the use of reflective roofing granules will alter the meteorology and human health outcomes during major heat events.  He presently serves as Chief Heat Scientist for the Arsht-Rockefeller Foundation developing the first international heat wave ranking system.  Kalkstein is co-founder of the Los Angeles Urban Cooling Collaborative developing a comprehensive neighborhood plan to lessen urban heat island negative health impacts.
