Professional Experience

PhD Candidate

Oct. 2021 - Dec. 2025

Leiden University Medical Center (LUMC), The Netherlands

Project goal: Rationally engineer catalytically active serine protease coagulation Factor X variants with reduced binding of small-molecule and natural inhibitors for therapeutic purposes

  • Sole computational scientist in a predominantly experimental group, translating complex simulation results for clinicians and experimentalists.
  • Analyzed experimental Factor X-small molecule inhibitor structures from the Protein Data Bank; generated additional complexes using molecular docking (HADDOCK, Schrödinger Glide) where structures were unavailable.
  • Prepared using Schrödinger Suite or AmberTools and simulated protein-ligand systems using AMBER, and/or Desmond.
  • Performed extensive molecular dynamics trajectory analyses, including RMSD/RMSF, protein–ligand interaction profiling, and binding free-energy calculations (MM/PBSA, MM/GBSA).
  • Performed per-residue free-energy decomposition to identify mutations that selectively weakened inhibitor binding, followed by targeted simulations of prioritized variants.
  • Modeled Factor X–natural inhibitor complexes using AlphaFold-Multimer, generating and refining multiple binding configurations via molecular dynamics simulations.
  • Identified interaction hotspots governing natural inhibitor binding; provided new detailed insight of their interactions and guided the design of inhibitor-resistant variants.
  • Developed a computational pipeline to assess the enzymatic competence of engineered variants despite overlapping substrate and inhibitor binding sites (currently under revision at the Journal of Chemical Information and Modeling).
  • Conducted all data analysis using Python, R, and GraphPad Prism; managed large-scale simulations via Bash scripting and Slurm job scheduling on HPC systems.
  • Generated appealing visual representations using PyMol and VMD.
  • Initiated and maintained external collaborations with researchers at Vrije Universiteit Amsterdam and the University of Basel.
  • Delivered regular presentations, posters, and oral talks, contributing to award-winning interdisciplinary conference presentations and funded grants.
  • PhD representative for the Dutch Association of Thrombosis and Haemostasis and LUMC.
  • Designed a project and supervised MSc student; taught and mentored MSc Biomedical Sciences students.
