PhD, West Virginia University, 1978
The overall goal of our research program was to investigate the interactions of environmental chemicals with leukocytes including polymorphonuclear leukocytes, mononuclear cells and their bone marrow progenitors. Disease endpoints of interest include aplastic anemia, agranulocytosis, leukemia and increased susceptibility to infections and cancer. Agents whose chemico-biological interactions are under investigation include benzene, polycyclic aromatic hydrocarbons, lead and agricultural chemicals. In this regard, our studies have focused in three areas: the bioactivation and molecular interactions of xenobiotics of interest; the biochemical and molecular regulation of myelopoiesis and cell differentiation; and the development of in vitro and in vivo models to provide a mechanistic basis for risk assessment and to develop chemoprotective strategies for myeloid cell toxicity. In order to accomplish the goals of the program we employ a spectrum of analytic, biochemical and molecular approaches including the use of chemilumigenic probing for which the laboratory is noted. This technology is based on the assessment of reactive oxygen by organells and cells. In this regard, our recent studies focus on the assessment and regulation of reactive oxygen by mitochondria.
From a translational environmental public health perspective, I am interested in the development and application of plant-derived nutraceuticals in environmental health and disease.
I am also interested in environmental public health education,from K-12 up to the community level .
