Background

My major fields of interest involve cellular mechanisms of inflammatory signaling cascades that control the responses to environmental toxic agents.In some studies, the laboratory investigates how proinflammatory signals (cytokines, toxins, and other stressors) interact with surface receptors to activate the stress-activated protein kinases and NF-kappaB and how activation of these pathways leads to transcriptional regulation of genes. Some projects involve the effects of ricin, a potential bioterrorist agent, on activating proinflammatory pathways in vitro and in mouse models.In other studies we are investigating the mechanisms that control the responses keratinocytes to environmental agents such as ultraviolet radiation and xenobiotic toxic agents.
