Dr. Contag, is a Professor in the Departments of Pediatrics, Radiology, Bioengineering and Microbiology & Immunology at Stanford University, and a member of the BioX Faculty for interdisciplinary sciences and the Immunology Faculty. He develops and uses noninvasive imaging tools that can simultaneously reveal the nuances of biological processes and provide an overall picture of health and disease. These tools are sensitive and image over a range of scales from micro- to macroscopic, and are well- suited for the in vivo study of cellular and molecular biology including miniaturized microscopes that can reach inside the body to interrogate disease states. He is applying these tools to study the interaction between the immune system and fetal development. He is currently president of the World Molecular Imaging Society (WMIS) and a Fellow of WMIS.
