Drexel Autism Institute. His current work focuses on identifying and measuring modifiable risk factors for autism spectrum disorder (ASD). The long term goals of this work are to bridge population and individual level scientific approaches and develop a public health approach to prevention of ASD. Current research projects include studies of environmental exposures, metabolic pathways involved in neurodevelopment, and molecular mechanisms that may mediate ASD. Other themes of research within the laboratory include carbon metabolism, cancer metabolism, immune cell metabolism, and drug metabolism. Additional projects include fundamental work on improving sample collection and analysis, as well as refining epidemiological trial design using laboratory measurements.
