My place of birth is the notorious town of Tombstone, Arizona although home while growing up was Helena, Montana. It is at Carroll College in Helena that I became interested in physiology. While studying physiology at the University of North Dakota I also became interesting in teaching and as a graduate student was entrusted to teach medical students endocrine and respiratory physiology. My interests outside science includes sports, I am an avid handball player and enjoy running and participating in triathlons. I am not as adept at music but I enjoy trying to play guitar.

My research interests are directed towards identifying the mechanism of airway hyperirritability that develops after exposure to airway irritants such as tobacco smoke. This airway hyperirritability seems to be selective to an induced hyperirritability of sensory afferents in the airways, specifically bronchial and pulmonary C-fibers. Our recent research is designed to determine if the neuropeptide content of the lungs increase after irritant exposure. Neuropeptides are mediators synthesized and released by lung C-fibers. The airway hyperirritability is enhanced in sensitized airways. We therefore proposed to determine if the cells involved in airway hyperirritability such as the eosinophils and alveolar macrophages become hyperirritable after exposure to airway irritants such as tobacco smoke.

Most recently I have explored the possible role of mast cells extracellular matrix formation of pulmonary fibrosis. Tools that will be used are the mast cell degranulator Compound 48/80 and the mast cell stabilizer sodium cromoglyate.
