Jesse Swen PharmD, PhD is a full professor of clinical pharmacy, in particular translational pharmacogenetics. He works as a clinical pharmacist-clinical pharmacologist at the Department of Clinical Pharmacy & Toxicology, Leiden University Medical Center where he is the chair of the laboratory of the hospital pharmacy. The long-term central goal of his career is to improve the outcomes of drug treatment by gaining a better understanding of the genetic mechanisms that result in inter-individual variability in drug response. To this end, he is working on the following research topics: • Dissecting the impact of rare, structural and regulatory variants on drug absorption, distribution, metabolism, and excretion (ADME) • Elucidating the mismatch between the drug metabolizer genotype and the capacity of an individual to metabolize drugs (phenoconversion). • Translating pharmacogenomics to patient care. This work is seamlessly integrated with his work as chair of the pharmacy laboratory. He has (co-) authored more than 200 (Web of Science indexed) articles in international peer reviewed scientific journals and several chapters in books. He is one of the primary investigators of the “Ubiquitous Pharmacogenomics” project (www.upgx.eu) and leader of the PREPARE trial that assessed the clinical utility of pharmacogenetics panel testing across 7 European sites. In addition, he is an active member of the Dutch Pharmacogenetics Working Group (DPWG) and the US Clinical Pharmacogenetics Implementation Consortium (CPIC).
