Rachel Marsh, Ph.D.
Associate Professor of Clinical Psychology (in Psychiatry)
Division of Child and Adolescent Psychiatry
Columbia University Medical Center
The New York State Psychiatric Institute
Dr. Rachel Marsh received a B.A. in Psychology from Skidmore College and a Ph.D. in Experimental Psychology from the City University of New York. The focus of her graduate work was on cognitive and language development in infants. During her postdoctoral training, she began developing expertise in fMRI techniques and studying the functioning and development of the fronto-striatal circuits that support self-regulatory capacities in healthy individuals and in those with psychopathologies that emerge during childhood and adolescence (e.g., Tourette Syndrome, Obsessive-Compulsive Disorder, and eating disorders). She is currently conducting a longitudinal multimodal MRI study aimed at understanding how abnormalities in overlapping frontostriatal neural circuits contribute to the persistence of Bulimia Nervosa over adolescence and adulthood. With her collaborators, Dr. Marsh is also studying how the circuits that support control and reward processes change following the remission of symptoms in adult and pediatric OCD, and how these circuits are involved in learning disabilities in children. In summary, Dr. Marsh’s research investigates the functioning and structure of the neural circuits that support self-regulation, learning, and memory in normal development and in the development of childhood psychiatric disorders. The overarching goal of this work is to determine when in development abnormalities in these circuits arise, so that we can determine where, when and how to intervene, and thereby prevent illness persistence.
Amy Margolis, Ph.D.
Principal Investigator, Promise Project Reading Study
Assistant Professor of Medical Psychology (in Psychiatry)
Amy Margolis has a Ph.D. in Applied Educational Psychology: School Psychology, and an MSEd in Neuroscience and Education from Teachers College. In the first decade of her career, she established a comprehensive assessment and treatment program for children with learning disabilities and attention disorders. In 2010, Dr. Margolis transitioned to a research career and completed the NIMH-funded T32 in research in child psychiatry in 2013, becoming an Assistant Professor in the Division of Child and Adolescent Psychiatry. Her research aims to understand how learning problems are related to underlying deficiencies in the structure and function of neural systems that support learning processes. With funding from the Promise Project at Columbia University, she is using MRI to examine how neural circuits that support cognitive control and learning processes produce reading disorder and with funding from the NVLD Project, she is studying children with non-verbal learning disability. Dr. Margolis is the recent recipient of an NIEHS-funded K award to study how exposure to neurotoxic chemicals may affect neurodevelopment and manifest as subsequent learning and social problems. Her research program seeks to inform the development of novel therapeutics and early prevention programs for people with learning disabilities.
Xiaofu He, Ph.D.
Assistant Professor of Clinical Neurobiology
Dr. He received his Ph.D. in Pattern Recognition and Intelligent Systems from Shanghai Jiao Tong University. During his graduate studies, he was trained in the research of image processing and pattern recognition with a focus on biometrics. During his postdoctoral training, Dr. He developed expertise in brain imaging including structural MRI, functional MRI (fMRI) and, particularly, diffusion tensor imaging (DTI). One of Dr. He’s long term goals is to bring together his expertise in image processing, pattern recognition, computational modeling, and neuroimaging to the challenge of understanding the developing brain, leading to more reliable findings in the important area of clinically oriented-neuroimaging research and to better understand the mechanisms of depression, and other psychiatric disorders.
Marilyn Cyr, Ph.D., Psy.D.
Post-doctoral Research Fellow
Dr. Cyr received a M.Sc. and a Ph.D. in experimental psychology and a Psy.D. in clinical psychology from the University of Quebec at Montreal (UQAM). Her graduate research focused on examining the role of brain neurochemical systems in cognition and behavior, using various techniques such as PET imaging. Her clinical pre-doctoral internship focused on the treatment of patients with pathological eating and patients with OCD. In recent years, she has developed an interest in the neurobiology and treatment of disorders characterized by deficits in self-regulation (inhibition, emotion regulation and impulse control), particularly eating disorders. Since joining Dr. Marsh’s lab, Dr. Cyr has examined alterations in brain circuits that support cognitive control, reward processing and learning in adolescents with bulimia nervosa. She’s using brain imaging, statistical models and machine learning to identify potential biomarkers of impulsive-compulsive behaviors and associated disorders.
Katie Davis, Psy.D.
Post-doctoral Research Fellow
Dr. Davis received her Master’s of Science and Doctor of Psychology degrees at Yeshiva University, followed by teaching fellowships. She then completed a postdoctoral clinical fellowship at the Brooklyn Learning Center, where she diagnosed and treated learning and attention disorders. Her clinical work and research as a doctoral student focused on the neurobiological bases and treatment of learning disabilities, and she is now working with Drs. Marsh and Margolis to study the functioning and functional connectivity of neural circuits underlying reading disorder in young children.
Mirjana Domakonda, M.D.
Post-doctoral Research Fellow
Dr. Mirjana Domakonda received her B.S. in Biology at The College of New Jersey, and earned her M.D. at The Pennsylvania State University College of Medicine. During medical school she developed an interest in childhood obesity and eating disorders, studying the impact of statewide BMI screenings on Pennsylvania’s school-age youth. Dr. Domakonda completed her Adult Psychiatry Residency at The University of Massachusetts Medical School. During her residency training, she refined her clinical skills and research interests, with an ongoing focus on disordered eating and its impact on psychological function. She recently completed her Child and Adolescent Psychiatry Fellowship at the New York-Presbyterian Hospital Child and Adolescent Psychiatry Residency Training Program of Columbia and Cornell Universities.
