👋 About Me

I am a soft matter physicist at Durham University, where I lead the Computational Multiphase Physics (CoMPhy) Lab.

Our research focuses on non-Newtonian free-surface flows and soft matter singularities—fluid phenomena (like drops, bubbles, jets, and sheets) where interfaces undergo rapid, dramatic changes. Using high-fidelity simulations, theoretical modeling, and collaborative experiments, we investigate events such as:

  • 💧 Droplet impacts and coalescence
  • 🫧 Bubble bursting dynamics
  • 🌊 Jet formation and breakup
  • 📄 Liquid sheet fragmentation

We use complex (non-Newtonian) fluids as model systems to explore how microstructural stresses influence continuum-scale dynamics, connecting fundamental insights to real-world applications across industry and nature.
