As part of Stanford's Pediatric Bipolar Disorders Program, Dr. Singh is currently conducting research in the phenomenology, neurobiology, pharmacology, and genetic aspects of bipolar disorder in children. These studies include brain imaging (MRI, MRS, fMRI), medication, and psychotherapy trials.

Dr. Singh enjoys traveling, cooking, reading, and singing. She hopes to one day run a full marathon and go hiking in Machu Picchu, Peru.


Amy Garrett, PhD
Research Scientist and Neuroimaging Manager

Dr. Garrett completed her graduate education at Wake Forest University, and postdoctoral education at University of California, Davis, and came to Stanford University to perform neuroimaging research in mood and anxiety disorders. Dr. Garrett uses MRI to study brain anatomy and function in psychiatric disorders.


Meghan Howe, MSW
Clinical Research Manager

After graduating from the University of Illinois with her bachelors, Ms. Howe received her M.S.W. from the University of California at Berkeley. For the past nine years Ms. Howe has worked with the child and adolescent population in therapeutic, educational, advocacy, and research settings. Under the mentorship of Dr. Chang, Ms. Howe has focused on specializing in the development, diagnosis, and treatment of pediatric bipolar disorder.

As lab manager, Ms. Howe assists in all research components of the Pediatric Bipolar Disorders Program, which include the phenomenologic, biologic, pharmacologic, therapeutic, and genetic studies of familial bipolar disorder. Ms. Howe is the co-author of papers and book chapters regarding pediatric bipolar disorder.


Donna Roybal, MD
Postdoctoral Fellow and Psychiatry Resident Researcher

Dr. Roybal is a Post-Doctoral Fellow and fourth year psychiatry resident at Stanford.  She completed both her B.A. and M.D. from UCLA, where she graduated as a Dean’s Scholar for her work on structural MRI research.  Prior to medical school, she conducted research in unipolar depression and was a ski instructor for the developmentally and physically disabled.  Her current interests include studying white matter tract alterations and fMRI findings in pediatric bipolar disorder.  She is also interested in complementary and alternative medicine treatments for mood disorders in children.  She will complete her clinical training as a Child and Adolescent Psychiatry Fellow while at Stanford.


Victoria E. Cosgrove, PhD
Instructor (Affiliated)

Dr. Victoria E. Cosgrove is an Instructor (Affiliated) in Psychiatry and Behavioral Sciences with the Pediatric Bipolar Disorders Clinic and Research Program at the Stanford University School of Medicine and a Postdoctoral Fellow with the Bipolar Disorder Research Program at the VA Palo Alto Health Care System. She hails from the East Coast and graduated in 1994 with a BA in Psychology from Yale University. Before attending graduate school, she was a Research Assistant in Boston and New York City for NIMH-funded projects investigating psychopharmacological and psychosocial treatments for bipolar disorder and schizophrenia. She graduated in 2009 from the University of Colorado at Boulder with a PhD in Clinical Psychology and an Interdisciplinary Certificate from the Institute for Behavioral Genetics, completing her Predoctoral Internship at the VA Palo Alto. Dr. Cosgrove's dissertation research examined the roles of candidate genes in adolescent bipolar disorder. During her first year of fellowship, Dr. Cosgrove has pursued a line of research investigating roles for life and family stress as well as inflammatory and neurotrophic pathways in the etiology and development of bipolar disorder. She is ultimately interested in exploring the effects of evidence-based psychotherapy on neurobiological and genetic pathways in children and adults with bipolar disorder.

In her spare time, she enjoys running with her beloved spaniel, Trinidad, on rolling, mid-peninsula trails.


Ryan Kelley, BS
Neuroimaging Research Assistant

Mr. Kelley graduated from UC Santa Cruz with a degree in Neuroscience and Behavior. As an undergraduate, he was involved in an environmental toxicology research study investigating behavioral effects of manganese neurotoxicity. Additionally, Ryan tutored elementary school children with learning disabilities and worked as a undergraduate student intern at Stanford’s Center for Interdisciplinary Brain Sciences Research developing behavioral stimuli programs. He enjoy the opportunities and lessons gained from mental health research.


Maisi Mayo, BA
Neuroimaging Research Assistant

Maisi attended undergrad at both, the University of Arizona and Argosy University School of Professional Psychology. Having majored in Psychology, she has spent the last four years as a research assistant within the Department of Psychology at UCLA and the Department of Neurosciences at UCSD. Specifics of research investigated include: Effects of early-life stress on brain development and using fMRI and neuropsychology to demonstrate how neural signals in the brain respond to faces. Additionally, she has been involved in many projects investigating brain structural differences in autistic infants compared to typically developing infants. Although her passion lies in studying brain structure and development and brain-behavior relationships, Maisi enjoys activities, such as surfing and scuba diving and once a month teaches adolescents how to cook a variety of Spanish dishes.


Spencer Boucher, BA
Neuroimaging Research Assistant

Spencer graduated from Rice University in 2011 with a double major in Psychology and Cognitive Sciences and a concentration in neuroscience. As an undergraduate, he worked as an intern at the Baylor College of Medicine’s Computational Psychiatry Unit, where he was introduced to neuroimaging and helped investigate neural responses to positive and negative auditory stimuli. He is grateful for the opportunity to work at Stanford with the most complex and interesting system in existence- the brain. In his spare time, he can be found reading, backpacking, slacklining, or hang gliding.


Paige Staudenmaier
Clinical Research Assistant

She has spent the last two years working as a statistical consultant, assisting in experimental design, data management, analysis, and interpretation. Last summer, she traveled to the beautiful city of Cape Town, South Africa and worked in an Addiction Treatment Unit. She hopes to attend graduate school in clinical psychology so she can one day work with patients struggling with mood related pathology on treatment research. Outside of academic interests, Jen loves hanging out with friends and family. playing with animals, doing yoga, cooking yummy food, and spending time outdoors.
