Research interests

Dr. Hammer’s research is focused on improving the physical and mental well-being of all workers in diverse industries through interventions designed to increase employee-supportive behaviors at all leadership levels. Her research focuses on ways in which organizations and employers 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 interventions with a variety of employee populations such as grocery and service industry, health care, construction, information technology, and government, as well as many others.

The COVID-19 pandemic has made Dr. Hammer's research more important now than ever, as the challenges faced by workers range from work-life stress, disparities in employees’ ability to work from home, and the increased need for employers to support worker safety, health, and well-being both at work and outside the traditional work environment. Many of these challenges have disproportionately affected women and employees of color.

Her current work extends this supportive supervisor training in the military domain, both with Active Duty Military and National Guard/Reserve Component service members. She is also working with Dr. Ellen Kossek on a project extending this training to sick and family leave policy support, as the nation adopts more state and national policies around such leave.  

Dr. Hammer is also Co-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.

Current research projects

The Oregon MESH Study is a Department of Defense-funded collaboration between Oregon Health & Science University, Colorado State University and Portland State University

The Oregon MESH Study, MESH.org is a Department of Defense funded intervention study which tackles 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 tests the effects of an intervention designed to improve the sleep of full-time National Guard members.

The Study for Employment Retention of Veterans (SERVe) was funded by the Department of Defense and active from 2013 to 2018. The research project was designed to make a positive difference in the lives of Oregon Veterans and current Service Members by improving their experiences in their civilian workplaces

SERVe (Study for Employment Retention of Veterans) (2013-2018)
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 investigated 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 to foster a supportive workplace environment. The SERVe training and behavior tracking programs are now available to the public.

Readiness Supportive Training for Leaders
Funded by the Department of Defense, this study will evaluates the effectiveness of our Readiness Supportive Leadership Training (RESULT) with active duty U.S. Army soldiers. We anticipate that the training program will have a positive impact on service member readiness and resilience, psychological health, team cohesion, and reduced loneliness. This research is designed benefit not only U.S. Army soldiers but service members across all military branches, as well as first-responders and other civilian occupations that face highly stressful situations as part of their work. This is a joint project with Portland State University. Read more about the project on the Oregon and the Workplace blog.

Past Research Projects

Safety & Health Improvement Program logo

The Safety & Health Improvement Program (SHIP) was designed to increase supervisor and peer support and decrease job strain, which play a key role in safety compliance and improved physical and mental health. SHIP integrates a focus on both health protection and health promotion by addressing psycho-social factors that are shown to be related to safety, well-being, and organizational productivity.

The SHIP intervention study was a NIOSH-funded randomized controlled trial focusing on supervisors and their teams. SHIP aimed to increase employee support from supervisors, improve team communication, enhance team effectiveness, and reduce stress and work-family conflict.

The SHIP intervention was composed of:

  • One-hour training for supervisors 
  • Behavior-tracking that reinforced the training principles
  • Team-based planning and problem-solving that utilizes a modified version of WFD Consulting's Team Effectiveness Process
  • Follow-up sessions

SHIP has been systematically  revised to apply across a wide variety of industries and organizations . The revised SHIP training is now available to implement in your organization.
