My original research training involved the application of engineering methods to inhalation toxicology experiments. Here at the University of Iowa, I have helped to develop exposure systems involving gases and aerosols in both small chambers forrodents and a large room-sized chamber for human studies. I am currently interested in the generation and analysis of nanoparticles. As co-investigator of a recent EPA grant on that topic I plan to pursue research in that area over the next 3 years with additional funding from NIOSH sought in the near future.

I am also using a small test chamber to do side-by-side comparisons of four sampling devices and aerosol photometers commonly used by industrial hygienists to measure aerosol concentrations in workplaces.

Another interest is in the use of mathematical models to determine the spatial variability of pollutants both indoors, with the use of a computational fluid dynamics software package, and outdoors with the use of plume dispersion model.

I am currently contributing to the funding of 3 Ph.D. students and one undergraduate.
