What is your greatest professional achievement?

My area of specialty is inhalation toxicology. For more than 20 years, I have studied exposures and human health risks of a number of different airborne constituents, including particles, fibers, volatile organics, and metals, in a variety of occupational, environmental, and consumer product settings. However, my research on beryllium has been one of my greatest professional achievements. The toxicology of beryllium is complex and still not fully understood today. The research that my colleagues and I performed evaluated the exposure-response relationship between occupational beryllium exposures and incidence of beryllium sensitization and chronic beryllium disease. This research identified exposure thresholds for beryllium sensitization and chronic beryllium disease, which ultimately served as the basis, in part, for lowering the occupational exposure limits for beryllium by the American Conference of Governmental Industrial Hygienists (ACGIH) and Occupational Safety and Health Administration (OSHA).

How is it making a difference?

The beryllium research that my colleagues and I conducted was used as a basis to lower the occupational standards for beryllium. Through these more stringent occupational exposure standards, it is anticipated that workers will be protected against the potential adverse health effects caused by beryllium.

What is your Service Line and why are you passionate about it?

Toxicology, exposure and human health risk assessment are my primary areas of practice, which have provided incredible opportunities for collaboration, problem solving, and original research of complex scientific topics.
