Angela Douglas is the Daljit S. and Elaine Sarkaria Professor of Insect Physiology and Toxicology in the Department of Entomology. She received a B.A. degree from Oxford, UK in 1978 and a Ph.D. from Aberdeen University in 1981. She was a Royal Society University Research Fellow (1985-1996) and Biotechnology and Biological Sciences Research Fellow (2005-8), and was a member of faculty at the University of York, UK (from 1997), before joining the faculty at Cornell in 2008. Dr. Douglas is currently a member of the American Society for Microbiology and fellow of the Entomological Society of America, and Royal Entomological Society of London. Dr. Douglas's research has been supported by the National Institutes of Health, National Science Foundation and the United States Department of Agriculture.

Research Description

All animals are chronically infected with microorganisms, most of which are benign or beneficial to their animal host. We study the three-way interaction between microorganisms and the nutrition and immune function of animals by a combination of genomic and physiological approaches, to understand how the associations between animals and microbial populations evolve and function. Our core questions include: How does the microbiota influence host nutrition, including susceptibility to metabolic disorders? And how are the composition and activities of the microbiota managed by the host immune system? Our research is focused in insects, both as tractable biomedical models for human-microbiome interactions, and to develop novel insect pest control strategies.
