Heather Bemis, PhD
Post Doctoral Fellow

Heather Bemis, PhD, is a Postdoctoral Fellow in the Nathanson Family Resilience Center (NFRC) at the UCLA Semel Institute for Neuroscience and Human Behavior. Her fellowship focuses on early childhood as a critical period for early intervention and developmental research. She is a family

In addition, she is developing a curriculum to bring a trauma-informed and family centered lens to the NICU environment.

Clinically, Dr. Bemis is trained in several evidence-based treatment approaches for children and families across a variety of populations and multidisciplinary settings, including medical systems. Her research focuses on coping, family interaction, and adjustment among families of children with medical illnesses, and in particular, the effects of socioeconomic disadvantage on these processes. Overall, her work aims to address social and healthcare disparities and to promote positive change at the individual, family, and institutional levels.

Dr. Bemis received her M.S. and Ph.D in Clinical Psychology from Vanderbilt University. She completed her predoctoral internship at the UCLA Semel Institute for Neuroscience and Human Behavior, in the Pediatric Consultation-Liaison track.

Minh-Chau Do, PhD
Post Doctoral Fellow

Minh-Chau obtained her doctorate in clinical psychology from San Diego State University/University of California, San Diego Joint Doctoral Program. Her post-doctoral fellowship with the NFRC focuses on working with various systems to disseminate the FOCUS model to increase resilience among families at high risk for experiencing trauma. She will work with systems such as the VA, the foster care system, and schools. Mihn-Chau previously worked at the Youth Stress and Mood Program (YSAM) with Dr. Joan Asarnow where she coordinated multiple clinical trials testing the efficacy and effectiveness of treatment protocols for adolescent depression and suicide. In graduate school, she worked at the Child and Adolescent Anxiety and Mood Program (ChAAMP) with Dr. Robin Weersing on clinical trials for youth anxiety and depression. One of her top priorities during her post-doctorate fellowship is to gain experience working with complex systems to develop a richer, more nuanced understanding of how to work effectively to improve mental health care for children and families. She hopes to continue her training in trauma, trauma-related conditions, and resilience, and to bridge this training with her prior experiences. Additionally, she is passionate about decreasing the stigma associated with mental illness, advocating for mental health parity, and working in a setting that allows her to be active in both research and clinical work.
