Research Interests

Dr. Hammer’s research is focused on improving the physical and mental well-being of workers through interventions designed to increase employee-supportive behaviors at all leadership levels. Her research focuses on ways in which organizations can help reduce work and family stress and improve positive spillover by facilitating both formal and informal workplace supports such as Family Supportive Supervisor Behavior training.

She has studied workplace intervention with such employee populations as grocery and service industry, health care, construction, information technology, and government, as well as many others. Her current work extends this supportive supervisor training in the military domain.

Current Research Projects


Oregon MESH (Military Employee Sleep and Health) Study (2016-present)
The Oregon MESH Study, MESH.org is a Department of Defense funded intervention study which will tackle the issue of sleep-related health concerns that are increasingly the focus of research in the military domain. The adverse effects of sleep deprivation are known to cause a variety of negative health and family issues. This study will test the effects of an intervention designed to improve the sleep of full-time National Guard members.
