General Research and Interest Areas

Over the past 11 years, I have established a diverse immunology research program. My lab has investigated the effects of broad spectrum antibiotics and mucosal integrity on oral tolerance, and in collaboration with my colleague, Susan McDowell, we have examined the effects of simvastatin on immune responses following primary and secondary infections with Staphyloccocus aureus

Currently, however, my lab is exploring aspects of herbal medicinal therapy and investigating specific immunologic mechanisms that can support or refute the effectiveness of these treatments. Presently, we are investigating the effect of extract from L. japonica on B and T lymphocyte functions. L. japonica is an herb commonly used in Chinese medicine and is known to have anti-inflammatory, anti-bacterial, and anti-viral effects. While many investigations involving L. japonica have examined its effects on innate immune responses, such as inflammation, little is known is about how it may alter adaptive immune responses involving B and T cells. While my lab is currently investigating the effects of the extract of L. japonica on adaptive immune functions, I have plans to expand our research to include additional herbs.
