ACoP8 2017 - Fort Lauderdale, FL, USA

Summary
 
A one day workshop on Modeling Delays in Pharmacokinetics and Pharmacodynamics will be presented by Wojciech Krzyzanski (University at Buffalo), Gilbert Koch (University of Basel, Children’s Hospital) and Johannes Schropp (University of Konstanz) on Sunday 15th October 2017. The course will provide an overview of biological systems exhibiting delays, concepts of lifespan driven pharmacodynamic response, modeling of cell maturation, and nonlinear mixed effect lifespan models. Delay differential equations (DDEs) will be introduced and implemented in R. The course will consist of both lectures and hands-on computer exercises. Source codes for DDE based PK/PD models and data will be provided to the participants. Contact wk@buffalo.edu for more information.

Instructors

Wojciech Krzyzanski, PhD, MA. Associate Professor at Department of Pharmaceutical Sciences,
University at Buffalo. Holds PhD in applied mathematics and MA in pharmacology. Research focus
on pharmacokinetics and pharmacodynamics of hematopoietic growth factors and pharmacometrics.


Gilbert Koch, PhD. Gilbert Koch holds a PhD in applied mathematics. He worked as Postdoctoral Associate at the Department of Pharmaceutical Sciences, University at Buffalo and recently joined the Pediatric Pharmacology Group at the University Children´s Hospital in Basel as Senior Research Fellow. His research focus is on delay/lifespan modeling, anti-cancer effects in combination therapy, modeling in pediatric drug development and rare diseases, and target mediated drug disposition with drug-drug interaction.
 
Johannes Schropp, PhD. Professor at Department of Mathematics and Statistics, University of Konstanz. Research focus on PK/PD modeling and numerics of dynamical systems.
