About the role

AI summarised

Postdoctoral research role focused on using all-atom molecular dynamics simulations to study pH-dependent conformational dynamics of coronavirus spike proteins across variants, aiming to inform vaccine design and diagnostics.

ResearchOnsiteBioinformatics Institute

Key Responsibilities

  • Investigate the pH-dependent structural dynamics and receptor-binding behaviour of coronavirus spike proteins across multiple variants
  • Understand how environmental conditions such as pH influence spike protein conformational states, ACE2 binding, and viral infectivity
  • Integrate all-atom molecular dynamics simulations, structural modelling, and quantitative analysis of biomolecular interactions
  • Characterise how spike proteins from SARS-CoV-2 variants respond to physiologically relevant pH conditions
  • Study how protonation states and environmental factors drive conformational transitions, structural stability, and compaction or aggregation behaviour
  • Analyse how these changes modulate receptor recognition and immune evasion
  • Extend principles of pH-dependent protein dynamics to complex viral systems
  • Perform comparative analysis across variants
  • Integrate experimental collaborations to validate predicted structural and functional changes
  • Generate mechanistic insights to inform variant-adapted vaccine design, improved diagnostics, and preparedness for future coronavirus outbreaks

Requirements

  • PhD in computational chemistry, computational biophysics, computational biology, or a related discipline
  • Extensive experience in all-atom molecular dynamics simulations of biomolecular systems
  • Analysis of protein structural dynamics, conformational transitions, and stability under varying environmental conditions (e.g. pH, ionic strength)
  • Experience in studying biomolecular binding interactions, including protein–protein, protein–receptor, or protein–ligand systems
  • Ability to analyse and interpret binding modes, interaction networks, and structural determinants of molecular recognition
  • Strong ability to interpret simulation results in a biological and mechanistic context
  • Experience with simulation packages (e.g. GROMACS, AMBER, CHARMM) and associated analysis tools
  • Familiarity with enhanced sampling methods or binding free energy approaches (e.g. MM/PBSA or related techniques)
  • Experience in trajectory analysis and handling large-scale simulation datasets
  • Scripting/programming skills (e.g. Python, Bash) for data analysis and workflow automation
  • Experience collaborating on interdisciplinary or experimental-led projects
  • A strong publication record in computational biomolecular research or molecular simulation studies is advantageous
