The Mood Disorders Research Program at UC Davis specializes in developing innovative approaches to evaluate, treat, and prevent mood and related disorders in youth, young adults and adults. The program has a three-fold mission of advancing scientific discovery, improving care, and training the next generation of clinicians and researchers dedicated to the research, treatment, and prevention of bipolar disorder.
Currently, the research program is embarking on a number of clinical trials to test the efficacy and safety of pharmacotherapies, behavioral therapies, transcranial magnetic stimulation and deep brain stimulation.

Our Focus Areas

Research
Our research focuses on unraveling the complexities of the origins and pathways of psychiatric disorders that start during childhood, and finding ways to protect and preserve function throughout lifespan.

Patient Care
Our research program seeks to investigate, measure and improve clinical care and outcomes for patients receiving psychiatric care for mood disorders and treatment-resistant depression.

Training
Our aim is to recruit, train and sustain the next generation of basic, translational clinical researchers in treatment resistant depression and other mood disorders, including bipolar disorder.
Our Research Team
Key Collaborators
We premise our research work on a collaborative, multidisciplinary approach.

Meet Our Team
Our researchers are active in the biology of mental illness and have published extensively on the neurobiology and psychopharmacological treatment of pediatric mood disorders. Currently, our team’s research and clinical interests involve testing the efficacy and safety of a spectrum of interventions including pharmacotherapies, behavioral therapies, transcranial magnetic stimulation, and deep brain stimulation.
Team members include:
Manpreet Singh, M.D., M.S., Program Director
James Bourgeois, O.D., M.P.A., M.D.
Matthew Settle, N.P.

Current Clinical Studies
We have the following clinical studies underway.
TRANSCEND Study
The TRANSCEND clinical study is for people with depression who have been unable to find relief from their symptoms after at least four antidepressant treatments. The study is evaluating the safety and effectiveness of deep brain stimulation for treatment resistant depression.
CReW BP-1 Study
The Bipolar CReW study is investigating how well Cariprazine, a treatment for Bipolar I Disorder, helps people in their everyday lives. This study will assess its benefits, how well patients can tolerate it, and its effects on their overall quality of life.
