of radiation dispersion in rural and urban and areas subsequent
to release from a nuclear accident. Reconstruction of plume
dispersion from the Chernobyl accident is permitting us to
document how radionuclides are deposited in forested
buildings and avenues, in waterways.
- Development of
accurate methods for estimating radiation dose in various
organisms exposed to environmental radiation.
dosimetry is a central tenet of my third area of research, the
biological/genetic effects of radiation. I collaborate with
excellent scientists (Drs. Robert J. Baker ,Carleton J.
Phillips, Brenda E. Rodgers, Jeffrey W. Wickliffe and others) to
assess genetic changes associated with acute, sub-acute, and
chronic doses of radiation. Methods employed include DNA
sequencing, karyology, fluorescent in-situ hybridization,
micronucleus assay, DNA-unwinding, flow cytometry, and
- The genetic
information within populations may be a function of
environmental factors as well as behavioral characteristics,
including mating and dispersal behavior,which is my fourth area
