Rosita Proteau's research page
University of Texas at Austin, B.S., 1991; Ph.D., 1996
Rosita Proteau's research focuses on the development of in vitro cellular models to explore and evaluate the mechanism by which xenobiotics damage or injure specific cell types of various organs or tissues. Rosita works with primary culture systems of liver, heart and skin as experimental models to study the cellular and subcellular toxicity of selected xenobiotics using sensitive indices of cytotoxicity. She also performs drug transport and metabolism studies using a variety of intestinal models.Â
