I am a Professor of Integrative Biology at The University of Texas at Austin, and a member of the External Faculty and Scientific Advisory Board of the Santa Fe Institute. I was trained as a mathematical biologist at Harvard and Stanford Universities, and my research foci include network epidemiology, optimization of infectious disease surveillance and control, and translational tools for public health.

I have trained numerous graduate students and postdocs that have gone onto successful careers in academia and industry, and lead an interdisciplinary team of scientists, engineers, social scientists and public health professionals in uncovering the sociological and biological drivers of influenza transmission, improving disease control policies for influenza and HIV, redesigning disease surveillance systems to harness next-generation data, and creating decision-support software for the Centers for Disease Control and Prevention (CDC), Association of Public Health Labs (APHL), Defense Threat Reduction Agency (DTRA) and Texas Department of State Health Services (DSHS).

Our research has been published in over 60 peer-reviewed publications and funded by research grants from National Institutes of Health, CDC, National Science Foundation, APHL, Texas DSHS, Canadian Institute of Health Research, and James S. McDonnell Foundation. The Wall Street Journal, Newsweek, the BBC, and other news sources have highlighted this work; and I have provided scientific expertise for government agencies, including the CDC, Institute of Medicine (IOM), Biomedical Advanced Research and Development Authority (BARDA), and US National Intelligence Council. In 2004, I was named by the MIT Technology Review as one of the top 100 global innovators under age 35.
