### Bio

Predescuâ€™s research interests are in mathematical modeling and analysis of discrete dynamical systems. Areas of inquiry have included global stability in population models in ecology and public health, and most recently, studying discrete models in social sciences. Recent research projects have focused on applying mathematical and statistical techniques to estimate model parameters. Research is a blend of theoretical work and computer simulations. Papers have appeared in Discrete and Continuous Dynamical Systems-series B, Applied Mathematics Letters, Advances and Applications in Statistics, Discrete Dynamics in Nature and Society. Presented at numerous conferences. Outstanding Scholarly Contribution Award, 2007. Predescuâ€™s current teaching interests are in applied mathematics and applied statistics.
