Our Team

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.

Martine graduated from Paul Valéry University of Montpellier with a BS in Clinical Psychology and earned a master’s degree in Social-Organizational Psychology at Teachers College Columbia University. She began volunteering for Dr. Marsh in 2011 and learned neuroimaging techniques. She was then hired as a research assistant and was responsible for project coordination, data organization and collection, and data quality assurance. During that time Martine developed clinical and technical expertise in acquiring imaging data from participants with anxiety disorders. In 2018, she was promoted to her current position as Lab Manager. She has since been supervising the lab’s operations across three research projects. Additionally, she oversees talent acquisition processes in the lab, from screening and interviewing applicants to training and mentoring new hires. As a supervisor, she also fosters organizational changes through developing training material, implementing career development initiatives, and promoting diversity, equity, inclusion strategies. 

Grace is currently working as a research coordinator for the neuroimaging portion of the COVID-19 Mother-Baby Outcomes (COMBO) Study. She graduated magna cum laude from Barnard College in May 2023 with a degree in Neuroscience and Behavior, with honors. Grace began working with the COMBO study in 2021 and, shortly after, with Dr. Marsh’s lab where she assisted with mother-infant MRI scans. In 2022, she joined CDNL as a volunteer and went on to complete a year-long neuroscience senior thesis project under the mentorship of Dr. Marsh. Grace plans to attend medical school in the coming years with aspirations of becoming a pediatric neurologist, a path confirmed by years of working closely with the COMBO study participants. With a deep appreciation for research, she hopes to continue working on pediatric neuroscience projects throughout her medical training and into her future career as a physician.

Tracey is an MD-PhD student at Columbia University currently pursuing her doctoral research with Dr. Marsh and Dr. H. Blair Simpson. She received a BA in Economics from Harvard University. Her current research focuses on the use of machine learning methods and resting state fMRI in the diagnosis and classification of psychiatric disorders such as OCD.

Helly is a student at Rutgers University graduating in May 2024 with a BA in Psychology and Political Science and a minor in Health Administration. In pursuit of in-person clinical experience, Helly has been volunteering at the Cognitive Development and Neuroimaging lab since July 2023, assisting with various different studies. Previously, she has worked at Robert Wood Johnson University Hospital-New Brunswick as a Child Life Intern. In addition to academic pursuits, Helly is committed to making meaningful contributions to the lab. She has learned from experienced professionals, gained hands-on experience with working in a laboratory, and assisted with various different studies. She plans to continue increasing her experience and eventually pursue her Master’s in Psychology.
