  • Doug Casa, PhD, ATC, FACSM, FNATA
    For Dr. Douglas Casa, the opportunity to prevent sudden death in sport is the culmination of a life-long path; his passion for the study of exertional heat stroke started in 1985 when he suffered an exertional heat stroke while running a 10K race. This experience motivated what has become his life’s cause: the study of exertional heat stroke, heat illnesses, hydration, and preventing sudden death in sport – his ultimate goal is to find ways to prevent needless tragedy during sport and physical activity. “I was fortunate to receive amazing care on-site from the athletic trainer; the EMT's in the ambulance; and at the hospital from the emergency room physicians and nurses. I only survived because of the exceptional care I received. I was just 16 years old at the time, but I have been driven by this experience since that day,” Dr. Casa explains when asked about what motivates him. He celebrated his 30th anniversary of surviving his exertional heat stroke on August 8, 2015. In April 2010 Kelci Stringer (Korey’s widow) and James Gould (Korey’s agent) asked Dr. Casa to develop and run the Korey Stringer Institute (KSI) at the University of Connecticut. Korey was an All-Pro offensive tackle for the Minnesota Vikings of the NFL. He died from exertional heat stroke in August 2001. The KSI (ksi.uconn.edu) serves the public to work toward preventing sudden death for athletes, soldiers, and laborers by mean of education, advocacy, public policy, research, media outreach, and publications. Additionally, he is the editor of a book titled: Preventing Sudden Death in Sport and Physical Activity (2nd edition, 2017), published by Jones & Bartlett in cooperation with the American College of Sports Medicine. For the past 17 years, Dr. Casa has worked toward his goal of preventing sudden death in sport at the Department of Kinesiology, College of Agriculture, Health, and Natural Resources, University of Connecticut. During this time he has published more than 175 peer-reviewed publications/book chapters and presented more than 350 times on subjects related to exertional heat stroke, heat-related illnesses, preventing sudden death in sport, and hydration. Dr. Casa has successfully treated 225 cases of exertional heat stroke (with 0 fatalities). In October 2010 the Department of Kinesiology doctoral program at the University of Connecticut was ranked number 1 in the country by the National Academy of Kinesiology (for 2010-2105). Additionally, in September 2010 the National Research Council ranked the faculty in the Department of Kinesiology number one for research productivity. Dr. Casa was named full professor at the University of Connecticut in August 2010.  In 2008 he was the recipient of the medal for distinguished athletic training research from the National Athletic Trainers’ Association.
