Research focuses on elucidating biological mechanisms by which social factors such as mindfulness, education, and early life adversity may influence cardiovascular disease. Dr. Loucks has generated research findings that have helped to better understand how biological factors such as inflammatory markers, epigenetics, blood pressure, obesity, lipids, amongst others, may be important mechanisms through which social factors could influence cardiovascular disease. He is now increasingly moving into practical applications of the work, including randomized controlled trials of mindfulness interventions for cardiovascular disease risk reduction.
