Our research focuses on understanding the neurodevelopmental trajectories of psychiatric disorders that arise during childhood and adolescence. We use multimodal magnetic resonance imaging (MRI) to study the functioning and structure of neural circuits that support the capacity to self-regulate one’s thoughts, actions, and urges, and the circuits that support learning and memory. We conduct studies aimed at assessing the neurodevelopment of these circuits in healthy children and adolescents and in adolescents with eating disorders. We also assess circuit-based changes following treatment in children, adolescents, and adults with obsessive-compulsive disorder.

Lab Members

  • Amy Margolis, PhD

    Principal Investigator, Promise Project Reading Study, Assistant Professor of Medical Psychology (in Psychiatry)

    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.

  • Xiaofu He, PhD

    Assistant Professor of Clinical Neurobiology

    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.

  • Marilyn Cyr, PhD, PsyD

    Post-doctoral Research Fellow

    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.

  • David Pagliaccio, PhD

    Assistant Professor of Clinical Neurobiology (in Psychiatry)

    Dr. David Pagliaccio received a PhD in neuroscience from Washington University in St. Louis. His graduate work with Dr. Deanna Barch 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. As a project manager with the Marsh Lab, he is using neuroimaging to explore alterations in brain circuitry and functioning relating to impulsive-compulsive behaviors, learning disorders, and other pediatric pathologies.

  • Lana Khamash, BA

    Research Coordinator

    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.

  • Sarah Banker, BA
