Josiah's project under the Humanware program with the Pervasive Technology Institute will apply cloud-based tools to neuroimaging research. The size and complexity of neuroimaging data is growing, and researchers are also building more sophisticated methods to analyze the data. Cloud-based tools can help researchers to disseminate methods, share data, and communicate results.
One way Josiah will apply the tools is to analyze a large neuroimaging dataset. The Adolescent Brain Cognitive Development study is following ten thousand adolescents for many years and will produce data too large for local computers to handle. Josiah will use cloud-based tools at Indiana University to analyze the data in order to test the following scientific questions: (1) how the structure and function of specific brain circuits might shape each other during adolescent development, (2) whether researchers can design automatic and reliable measurements of targeted brain structures, and (3) can brain measurements in early life perhaps predict future life outcomes like problematic drug use?
Josiah is a postdoctoral researcher in the laboratory of Franco Pestilli at Indiana University Bloomington. He got his PhD in psychology from Stanford University, where he studied structural connections in the brain that help people inhibit themselves when tempted by incentives like drugs and money. Before his doctoral studies, he researched Alzheimer's disease at University of California, San Francisco, and before that he studied psychology at University of California, Berkeley. His research interests include how the brain creates emotions and how emotions influence risky choices.
