Dr. Rachael Neilan an associate professor of mathematics at Duquesne University. Her research expertise is in mathematical biology with a focus on agent-based modeling and optimal control theory. Much of her research involves the development and use of computational and mathematical models to study population and disease dynamics. Dr. Neilan has a long-standing history of including undergraduate and M.S. students in her research. All of her student researchers have presented their work at international, national, or regional conferences and many have won awards for their outstanding research contributions. Dr. Neilan frequently co-authors research publications with these students. She also serves as the faculty director for the Applied Math B.S. program.
