👋 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.

I merged a PR with failing checks I have participated in pull requests with 5 or more people I found the answer to the ultimate question of life, the universe, and everything! I closed an issue that was open for a year I joined GitHub 10 years ago. I have five or more public keys One of my commit sha starts with "a". One of my commit sha starts with "ab". One of my commit sha starts with "abc". I committed on the day when the crew of the USCSS Nostromo made their fateful landing and discovered the Xenomorph on LV-426! I did a little housekeeping! 🧹 I made cosmetic commit. I committed on the day Doctor Emmett Brown invented the flux capacitor! I made an epic commit with a message over 500 chars. My favorite word is "add". I did 2 sequential fixes. I did 3 sequential fixes. I did 4 sequential fixes. I did 6 sequential fixes. I committed on Friday the 13th, One… By One… When I delete code, I delete a lot. When I delete code, I delete a lot. May the 4th be with you! Happy March 14th! I committed on a Pi Day! Happy Programmers Day! I committed on a 256 Day of Year! I committed on Isaac Asimov's birthday / National Science Fiction Day! I committed on the Halloween! Boo! I committed on St. Patrick's Day! I collected 100 stars. I am a sleepy coder. I commit in the morning. I commit in the evening. I commit at midnight.
