RESEARCH INTERESTS

Aerosol transport in confined spaces: The transport and simultaneous interaction of aerosols with each other and the environment is a complex problem that has a wide scale of applications. My current work forcuses on computer code development to predict the spatial and temporal transport of poly-disperse systems. The code is validated using experimental benchmarks obtained in my aerosol lab at the Nuclear Science Center. Applications include therapeutic delivery of medicine through the bronchial tract, and indoor dispersion of radioactive particles.

Radiation Biophysics: With Dr. William Lee (Institute of Mutagenesis) we are investigating the risk of heritable intragenic mutation with varying linear energy transfers (LET). The objective of this work is to test the hypothesis that among different qualities and its quality factor for intragenic mutations are different from that for translocations and large, > 20 kilobase, delitions. Our research shows evidence that most of the susceptibility genes are intragenic mutations. Our hypothesis is that intragenic mutations are produced by a single cluster of ions from low LET Radiation that induces a double-strand break in DNA, whereas large deletions and translocations require either multiple implications for cancer treatment using low vs high energy gamma radiation.
