Gilbert Koch, PhD, is a multidisciplinary scientist in the area of pharmacokinetics (PK) and pharmacodynamics (PD) modeling. In this field the major goal is to describe biological and pharmacological processes based on mathematical principles in order to obtain e.g. more insights in disease progression and to optimise drug administration. He obtained his PhD from the Mathematical Department at the University of Konstanz where he investigated theoretical concepts of PKPD models especially for delay and lifespan modelling, and performed preclinical drug-drug interaction modelling in oncology funded by Nycomed (a Takeda Company). He became a Postdoctoral Associate funded under the Marie Curie Actions of the European commission in the Department of Pharmaceutical Sciences at the University at Buffalo, NY, where his research was focused on fundamental modelling principles. Gilbert is co-organiser of the annual workshop "Modelling Delays in PKPD" and lead author of the book chapter "Mathematical Concepts in Pharmacokinetics and Pharmacodynamics with Application to Tumour Growth," published in 2013 in Lecture Notes in Mathematics. Recently, he joined the Paediatric Pharmacology Group at the University Children's Hospital in Basel, where he performs paediatric and rare diseases modelling.
