Abigail Horn, Ph.D., is a Research Assistant Professor of Industrial and Systems Engineering and Research Lead in the Information Sciences Institute (ISI) at USC, where she is a Co-Director of the AI4Health Center. She previously conducted postdoctoral fellowship training in Health Behavior and Biostatistics in the Department of Population and Public Health Sciences at USC. She obtained her PhD from the Institute for Data, Systems, and Society at MIT. The general area of her research is the combination of approaches from computational social science, systems modeling, and AI with large-scale data sources to design solutions to pressing public health challenges related to food systems, from food safety to nutrition. Current research includes analyzing big mobility data from smartphones to understand visits to food outlets and impacts on nutritional health, using digital menu data to predict the nutritional quality of restaurant menus, and modeling food supply chain network structure for applications in foodborne disease to food security.
