Research interests

My primary focus is on undergraduate teaching in the fields of cell biology, animal physiology and toxicology. My interests in these areas are in cellular toxicology, in vitro methodology development and animal cell biotechnology. My research interests include investigating the use of cell cultures and protozoa as alternatives to the use of whole organisms in toxicology research and the effects of different classes of toxicants on cells.
