Curriculum Vitae

Physiological Environment Research Facility (PERF)

The generation of free radicals and reactive oxygen species was long thought to be nothing more than a detrimental and damaging process to cells. In recent years, this dogma has shifted and it is now appreciated that the redox environment is essential to normal cellular functioning and signaling. The overarching theme of my research is to examine the role of the redox and metabolic environment in regulating T-lymphocyte function in models of psychological stress.

The term psychological stress encompasses a broad spectrum of disorders ranging from generalized anxiety to post-traumatic stress disorder (PTSD). While these conditions have well-characterized psychological manifestations, often overlooked are the physiological changes to the rest of the body. It has been shown that patients suffering from PTSD have increased risk for both immune disorders and cardiovascular diseases. Our working hypothesis is that these secondary maladies stem from dysfunctional autonomic nervous system function due to the stressing condition. More specifically, we believe an over-abundance of norepinephrine (NE) from the sympathetic nervous system modifies the immune system to be auto-reactive and pro-inflammatory. Understanding the molecular pathways involved in this process may elucidate innovative targets in the immune system that may help treat these secondary diseases, and may also improve psychological function in these patients as well.
