Jonathan Bricker

My lab develops and tests acceptance-based therapies delivered in digital and telehealth platforms, with a focus on addressing health disparities. The most preventable causes of premature death and human suffering are cigarette smoking and obesity. To this end, my research team focuses on designing, developing, and testing AI-based chatbot, smartphone app-delivered, and telephone coach-delivered contextual behavioral interventions for smoking cessation and for weight loss. Research aims include main outcome comparisons, mediators, moderators, intervention engagement, and therapeutic process predictors of outcome. This research is currently supported by multiple NIH R01-level grants. Our lab’s latest grant focuses on testing a smartphone app for helping American Indians and Alaska Natives stop smoking commercial cigarettes.

Personal Statement

My research focuses on understanding and addressing the contextual factors like social support and policy that affect health and health behavior. I completed a VA Health Systems Research (HSR) Career Development Award focused on developing a behavioral weight management program for Veterans with PTSD called MOVE!+UP (2015-2020). We are currently testing MOVE!+UP in a VA HSR Merit-funded study using a hybrid effectiveness and implementation RCT design. I recently led another VA HSR Merit-funded study as Principal Investigator (PI) to test a self-directed behavioral weight management intervention among 500 Veterans with obesity; the findings were published in JAMA: https://jamanetwork.com/journals/jama/fullarticle/2799407. I am Co-PI for two additional VA HSR Merit-funded studies, both RCTs testing behavioral interventions that harness the power of social support. Last, I am Co-PI for a VA operations-funded project called MOVED By LOVE, a multi-method study that is partnering with Black Veterans to enhance how weight management care in VA serves Black Veterans. The first findings from the study were recently published in the Journal of General Internal Medicine: https://link.springer.com/article/10.1007/s11606-024-08628-7. I am fortunate to work with Veterans with PTSD as a staff psychologist in the VA Puget Sound-Seattle PTSD Outpatient Clinic. Lastly, I have an interest in maximizing research impact by communicating about science with Veterans, the public, institutions, and policymakers.

Tiffanie Fennell

As a board-certified clinical health psychologist, I have primarily focused my clinical work on preventive medicine with special expertise in diabetes, weight management, and tobacco use cessation. I train clinicians in motivational interviewing and health coaching, and am currently a co-investigator on a research study examining an intervention with peer health coaches in the Veterans Health Administration (VHA). After nearly two decades of working in complex healthcare settings, like the VHA and serving in several leadership roles within and external to the VHA, I have grown a passion for supporting those who serve others and improving workplace well-being. I am an Associate Certified Coach and am enrolled in a Masters program in Leadership and Organizational Development. I coach leaders and individual contributors on their professional and personal goals, help teams work better together, engage clinics in identifying and implementing meaningful changes to improve workplace satisfaction.
