Hey there!

I’m Pema. I write code - sometimes. I’m particularly interested in graphics, virtual reality, programming language development, functional programming and pure mathematics. I’m currently working at Unity, on the light transport team. Check out my stuff, if you want, and feel free to reach out on any socials.

I also run a blog and host my personal notes on this domain.
