I am an associate professor at the University of Minnesota School of Nursing. My interests focus on promoting health and wellness across diverse older adult populations with fall risk. I lead and participate in interdisciplinary research to develop and test behavior change strategies within community-based, fall-reducing physical activity interventions. My long-term goal is to help people stay motivated and integrate fall-reducing physical activity (e.g., balance and leg strengthening exercises) into their everyday lives. My work has been funded by agencies and organizations, including the National Institute of Nursing Research. From 2014-2017, I received support through the University of Minnesota's Clinical and Translational Science Award-funded KL2 Scholars Career development Program.
