OverviewAI-generated summary

Josiah K. Leong is a biostatistician whose research focuses on understanding the structural and functional aspects of the human brain, particularly in relation to behavior and neurological conditions. His work utilizes advanced neuroimaging techniques, such as magnetic resonance imaging (MRI), to map brain structures and their connections. Leong has investigated the link between the structure of brain tracts and the relapse of stimulant drug use, and has explored how structural projections to the nucleus accumbens correlate with impulsive decision-making. His research also examines sex-specific vulnerabilities in externalizing behaviors during adolescence, considering the role of early stress and nucleus accumbens activation. Additionally, Leong has contributed to the development of brainlife.io, an open-source cloud platform designed to support neuroscience research by facilitating decentralized data processing and analysis. His scholarly output includes 35 publications, with an h-index of 11 and over 500 citations.
