Dr. Misty Hawkins

Lab Director, Associate Professor at Indiana University

The REACH Lab is run by Dr. Misty A.W. Hawkins, an associate professor in the Department of Health & Wellness Design at in the School of Public Health IU. Dr. Hawkins is a clinical health psychologist and behavioral medicine researcher on a mission to understand the relationships between emotional factors (e.g. depression), cognitive factors (e.g., executive function), chronic diseases (e.g., obesity, cardiovascular disease) and health behaviors (e.g., eating, exercise, breastfeeding). She believes that understanding how the way we feel and think impacts our physical health (and vice versa) is the first step in combating hard-to-treat health conditions like obesity or promoting healthy behaviors like exercise and breastfeeding. When she's not doing research, Dr. Hawkins uses Netflix, Hulu, and PBS shows to keep her motivated on the treadmill (e.g., Downton Abbey, Drop Dead Diva, Dexter). Of course, running after and snuggling with her kid helps keep happiness well within reach.
