Dr. Marshall received his Sc.B. with Honors at Brown University and his Masters and Ph.D. at Kansas State University. He then completed a 2-year postdoctoral fellowship at the University of California, Irvine, followed by a 3-year postdoctoral fellowship at Children's Hospital Los Angeles / University of Southern California. Dr. Marshall serves as a co-investigator for the CHLA site of the Adolescent Brain Cognitive Development Study (https://abcdstudy.org/), along with his roles of membership and leadership of several workgroups within this seminal research study.

Research Interests: 

His research program generally includes developmental cognitive neuroscience, focusing on brain and cognitive development in children and adolescents, and how these developmental trajectories are influenced by environmental factors. Dr. Marshall is particularly interested in exploring how correlates of socioeconomic status impact neurocognitive development, especially those pertaining to environmental exposures (e.g., lead exposure). Having come from an animal-research background, Dr. Marshall is also interested in incorporating animal models into his research program, with the goal to employ animal models of environmental exposures, too. Dr. Marshall's interests also include risky and impulsive decision making. He has published over 35 papers thus far.
