Dr. Gombart is a Principal Investigator in the Linus Pauling Institute and professor in the Department of Biochemistry and Biophysics in the College of Science at Oregon State University. He joined the faculty in 2008 after working as a Research Scientist in the Division of Hematology/Oncology at Cedars-Sinai Medical Center and as an adjunct assistant and associate professor at the David Geffen School of Medicine at UCLA. He is actively engaged in leading and facilitating interdisciplinary basic and translational research projects both within OSU and across the US. He is strongly committed to educating, training and mentoring post-doctoral researchers, undergraduate and graduate students who wish to pursue careers in the biological and medical sciences; and educating the public through outreach activities.

Research Interests

Dr. Gombart’s group discovered that vitamin D induces the expression of an antimicrobial peptide in humans and primates. His research is focused on understanding the role this regulation plays in immunity, wound healing and barrier defense, and how pathogens may interfere with this regulation to evade the host immune response. Using unique mouse models, his group is determining the possibility to speed wound healing while combating infection by inducing the peptide with nanofiber bandages that release bioactive vitamin D. His group has also identified a potential role for the antimicrobial peptide in bone formation and is working to understand the molecular mechanisms by which it works. In addition, the lab works on understanding how a hops plant polyphenol, xanthohumol, improves obesity and metabolic syndrome through its interactions with host and the microbiota. The overall goal of his research is to develop potential therapies to improve human health.
