Research Interests

I am interested in applying sleep and circadian principles to improve occupational safety. My work has primarily focused on the occupational safety of emergency medical services providers, who are often faced with challenging work schedules and operational demands in a high risk environment. I am further interested in communicating the value of identifying and treating common sleep disorders in the occupational setting.
