Dr. Koci is a virologist and immunologist and his research, teaching and outreach program is focused on host-pathogen interactions and understanding how the gut immune system tells friend from foe.

Dr. Koci’s laboratory works to understand the immune mechanisms which allow an animal to recognize, respond, eliminate and develop resistance to pathogens. The lab’s approach involves understanding both cellular and molecular aspects of the host response. Currently there are three primary research projects in the laboratory: 1) understanding the key innate immune responses involved in pathogenesis and disease resolution of astrovirus induced gastroenteritis, a major cause of diarrhea in turkey poults and humans, 2) understanding how genetic polymorphisms in innate immune response genes affect resistance and susceptibility to infection, and 3) understanding how changes in the intestinal microflora affects gut physiology, mucosal immunity and, ultimately, the overall health of the animal.
