  • Graham received his B.S. from Cornell University in 2012, and spent two years as a research fellow at the National Institute of Mental Health in the Genes, Cognition, and Psychosis program. Graham recently completed his PhD in Neuroscience at the University of Pennsylvania, where he applied tools from network science to delineate how white matter architecture develops to support improvements in executive function during adolescence. Currently, Graham is interested in identifying circuit-level markers of brain maturation that are linked with individual differences in working memory, inhibitory control, and decision-making. Outside the lab, Graham enjoys hiking with his dog Huxley, exploring cities by bike, and thinking about the stochasticity of evolution.

  • Garth received his BA in Psychology and Neuroscience from Skidmore College. He went on to get his PhD in Psychology from Harvard University working with Prof. Randy Buckner, and is staying local as a Postdoctoral Fellow with Prof. Leah Somerville. Garth’s research interests are in dynamics between sleep behaviors and experiences of stress, and how their interrelationships may shed light on factors that put us at risk for, or make us resilient to, developing psychiatric disorders, particularly during major life transitions such as adolescence or beginning college. Garth also teaches in the Psychology Department as a College Fellow. Outside of lab, Garth enjoys movie nights with his cats, exploring the city for new places to eat, and board games with friends.

  • John is a research scientist working with Drs. Leah Somerville and Kate McLaughlin at Harvard University. He came here by way of the psychology Ph.D. program at the University of Oregon, and a B.A. in cognitive science at the University of California, Berkeley. John is interested in the development of decision-making and learning during adolescence, and how these processes, situated in the context of developmentally normative goals and adverse environments, contribute to mental and physical health. He is am passionate about statistical methodology, especially measurement and modeling task behavior, as well as scientific computing. John is a huge fan of R, Stan, and The Society for the Improvement of Psychological Science.

  • Melanie graduated from Yale University in 2019 with a B.S. in Psychology. As an undergraduate she worked on the Adolescent Brain Cognitive Development (ABCD) Study with Dr. BJ Casey, and continues to explore her interest in the fields of developmental and abnormal psychology with her work on the Human Connectome Project in Development in the Somerville Lab. She is particularly interested in using neuroimaging methods to investigate the developmental trajectories of mental illnesses. Outside of the lab, Melanie loves camping, dancing, and continuing her search for the best cheesecake in the world.
