Dr. Mascotti joined John Carroll's faculty in the summer of 1998. He completed his Ph.D. in 1992 studying nucleic acid chemistry and the interactions of synthetic peptides (that served as simpler models of proteins) with DNA and RNA. After completing his Ph.D., Dr. Mascotti accepted a National Institutes of Health Postdoctoral Fellowship to work at Washington University in St. Louis. While there, he studied iron metabolism and the control mechanisms of ferritin synthesis. After his postdoctoral work, he was an assistant professor at the Richard Stockton College of New Jersey for two years. He now teaches general chemistry, biochemistry, and is a Faculty Fellow in Entrepreneurship at JCU where he has taught Introduction to Entrepreneurship as part of the Entrepreneurship Minor. His current research interests include continuation of his earlier efforts to understand the chemical forces governing protein-nucleic acid interactions, as well as how those interactions influence gene expression.
