Dr. Rachel Marsh received a BA in psychology from Skidmore College and a PhD 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 frontostriatal 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.
Cognitive Development & Neuroimaging Lab
Who We Are
Dr. David Pagliaccio received his PhD in neuroscience from Washington University in St. Louis. His graduate work with Drs. Deanna Barch and Joan Luby focused on the effects of stress and stress-system genes on brain structure and function in children with early-onset depression. During his postdoctoral fellowship with Drs. Daniel Pine and Ellen Leibenluft, Dr. Pagliaccio continued fMRI research to examine the neural underpinnings of pediatric anxiety and irritability. His research aims are to use neuroimaging and other methods to understand the mechanisms underlying psychiatric disorders in youth, particularly affective psychopathology, as well as to assess the psychometrics and reliability of currently used research methods. With his collaborators at the Columbia University Irving Medical Center/New York State Psychiatric Institute, Dr. Pagliaccio is exploring alterations in brain circuitry and functioning relating to affective disorders, OCD, learning disorders, and other pediatric pathologies.
Marilyn Cyr, PhD, PsyD
Dr. Cyr received a MSc and a PhD in experimental psychology and a PsyD 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 predoctoral 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.
Amy Margolis has a PhD 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 & 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 PROMISE at Columbia, 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 nonverbal learning disorder. 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.
Dr. He received his PhD 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.
Martine Fontaine, BA
Martine obtained a BA in psychology from Paul Valéry University of Montpellier, where she also completed the first year of a MA in clinical psychology and mental health. She began training at the Institute of Family Therapy in France before moving to the US. Martine began volunteering for Dr. Marsh in 2011 and learning neuroimaging techniques. She is now responsible for acquiring multi-modal imaging data from our research participants with bulimia nervosa, obsessive-compulsive disorder, and healthy control participants. She is also responsible for processing the anatomical data acquired for these participants. Martine is currently expanding her knowledge of computerized brain models by beginning an introduction to FreeSurfer (a software program). These diverse experiences are allowing Martine to explore her research interests prior to pursuing a PhD in clinical psychology.
Lana Khamash, BA
Lana Khamash graduated from Columbia University in 2018 with a BA in psychology. As an undergraduate, she worked as a research assistant in the Developmental Affective Neuroscience Lab, where she studied early life adversity and its relationship to neurodevelopment and psychopathology. Her current role at Dr. Marsh’s lab involves coordinating pediatric fMRI studies and clinical trials that examine the neural underpinnings of OCD and anxiety. Lana is involved in the collection, processing, and analysis of both neuroimaging and clinical data, and she is interested in employing this understanding of the mechanisms behind psychiatric disorders to inform the development of early intervention strategies. In the future, she hopes to pursue a doctoral degree in clinical psychology.
Anna Seraikas, B.S.
Anna Seraikas, B.S., graduated from Union College in 2016 with a degree in Psychology. She coordinates an NIH funded grant investigating the intergenerational transmission of deficits in self-regulatory control. She is involved in the collection, processing, and analysis of both neuroimaging and clinical data. Her research interests lie mainly in investigating the neural mechanisms that underlie pediatric anxiety and OCD. She is particularly interested in the effect that early life adversity and anxiety have on brain development, and in turn, the use of different interventions to examine treatment outcomes and trajectories through adulthood. Anna plans to attend graduate school in clinical psychology.
Sarah Banker, BA
Sarah Banker graduated from Wesleyan University in 2017 with a BA in neuroscience and behavior. As an undergraduate, Sarah worked as a research assistant in a neuro-immunology lab studying multiple sclerosis and in a neuroscience lab studying the development of the visual system.
