Hey everyone!
I’m Palash Chitnavis, a GSoC 2025 contributor. This summer, I’ll be working on Project #7 Brian Simulator :: Brian2Wasm: simulations in the browser (175/350h). I’m really looking forward to working with my mentors Marcel Stimberg, Dan Goodman, and Benjamin Evans.
What am I working on?
We already have a repo called Brian2Wasm that lets users run Brian2 code directly in the browser. My goal is to turn this early demo into a practical and easy-to-use tool for the wider community. I’ll be working on releasing a conda package, adding tests, improving the build pipeline, and making the setup smoother so users can run and share simulations with minimal effort.

Looking forward to learning from and collaborating with this amazing community
