Data Scientist at Centre for Human Drug Research


The Centre for Human Drug Research (CHDR) is a top class contract research organization located in Leiden, the Netherlands. CHDR focuses on early phase clinical research, trying to bring its customers’ drugs to proof of pharmacology and proof of concept as quickly and efficiently as possible. CHDR originates from the Leiden University Medical Center, and is established as an independent organization. It is unique in combining industry standard processes and quality with top level science and methodology.

The Method Development department within the Centre for Human Drug Research (CHDR) designs and develops new (neuro)-physiological and (neuro)-psychological tools. These tools aim to demonstrate the safety and effects of drugs on healthy volunteers and patients. A few examples of technologies we are working on include remote monitoring of social and physical activity, virtual reality, and electrophysiological sensors. We also develop and validate the techniques to analyze datasets.
