Wojciech Krzyzanski holds a Ph.D. in Applied Mathematics and an M.A. in Pharmacology and Toxicology, both from the University at Buffalo. Krzyzanski’s research focuses on the pharmacokinetics and pharmacodynamics of drugs acting on cell populations. He applies pharmacometrics modelling principles to improve existing therapies in several areas, including hematopoietic growth factors, corticosteroids, and anti-infectives. His research methods utilise dynamical systems and nonlinear mixed effects modelling. As a Fellow of the International Society of Pharmacometrics, Krzyzanski serves as Associate Editor for the Journal of Pharmacokinetics and Pharmacodynamics. His significant contributions to the field include co-authorship of three book chapters and publication of over 110 articles in peer-reviewed journals. Krzyzanski's work bridges the gap between mathematical modelling and pharmaceutical sciences, contributing to the advancement of drug development and therapeutic strategies.
