Leslie B Hammer PhD

Dr. Hammer has expertise in Occupational Health Psychology and specializes in the health effects of supportive supervision at work, and on the health consequences of work-family conflict. She has extensive experience in designing, implementing, and evaluating worksite interventions and supervisor training. 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.

Dr. Hammer is also an Associate Director of the Oregon Healthy Workforce Center, one of six Total Worker Health® centers of excellence funded by the National Institute for Occupational Safety and Health.  She was the Principal Investigator of the Phase I and Phase II Work, Family & Health Network (WFHN) Portland State University projects involving developing and evaluating a work-family intervention, namely Family Supportive Supervisor Behavior Training.

Oregon MESH (Military Employee Sleep and Health) Study

The Oregon MESH Study is another 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. 

SERVe (Study for Employment Retention of Veterans)

SERVe is a Department of Defense funded intervention study aimed at improving the health and well-being of service members and their families by targeting the workplace experiences of Veterans and Service Members who are members of the civilian workforce. Conducted as a randomized control trial, SERVe is an ongoing investigation into the effects of an intervention which combines training and behavior tracking to improve the knowledge and skills of supervisors with service members in their employ in order to foster a supportive workplace environment. Read more about the SERVe program here

The Sandwiched Generation

Along with her colleague Dr. Margaret B. Neal, Dr. Hammer researched the modern phenomenon of working couples who care for both children and aging parents and coined them the "Sandwiched Generation". Her research guides evidence-based practices aimed at improving the health and well-being of these couples.
