About

Full Professor AI & Medicinal Chemistry, group leader Computational Drug Discovery at the LACDR at Leiden University, AI Platform Lead in Oncode Accelerator. I am an expert in the application of artificial intelligence on combined chemical and biological data (proteochemometrics). In my group, large language models are used to design (generate) new molecular structures with a desired activity and toxicity profiles that are subsequently synthesized in the wet lab. Moreover, structure-based approaches are used to gain a mechanistic insight in the molecular interaction between small molecule ligands and (membrane bound) protein targets. Here dynamical methods are created that are subsequently analyzed using AI approaches to design and improve small molecule ligands. Previously a postdoctoral Marie-Curie / COFUND fellow at the European Molecular Biology Lab - European Bioinformatics Institute supervised by John P. Overington. PhD was in proteochemometric modeling in a joint project between Janssen Pharmaceutica (Johnson and Johnson) and Leiden University. Peer reviewed publications: 130+, h-Index 44.

  • Guest Researcher at Leiden University Medical Center
    Apr 2017 - Present · 9 yrs 4 mos

  • Owner at Getuyg Data Analytics Consultancy
    Jul 2015 - 2024 · 8 yrs 7 mos

    http://www.getuyg.com Getuyg is a company that consults in data analysis and data driven decision-making (or 'big data' driven). Getuyg can consult on all parts of the process, data storage (both software and hardware), data curation and adaptation, data mining, data visualization, data modeling, and data driven decision making. Key expertise is available in machine learning (deep learning) and dimensionality reduction. Getuyg works both with open and closed source solutions. In technical jargon, the company has an expertise working with random forests, deep learning, dimensionality reduction, multi-objective optimization, text mining, and GPU computing. The name Getuyg is an old Dutch term used to indicate ‘a miner’s tools’. As there are many similarities in data analysis and traditional mining (even found in the term ‘data mining’) this seemed appropriate.

  • Visiting Scientist at Xi'an Jiaotong University
    Sep 2017 - Sep 2020 · 3 yrs 1 mo

    In order to strengthen the strategic collaboration between the Faculty of Science at Leiden University and Xi'an Jiaotong University I have been appointed a visiting scientist. I am connected to the School of Electronic and Information Engineering. The collaboration includes shared supervision of PhD students and teaching a course to postgraduates in Xi'an.
