about me.

my name is leon ericsson, i live in stockholm with my sambo. i've recently graduated with a master's degree in cs, during which i realized the joy for research which i still hold. apart from that, i enjoy food eating and food making, traveling and the gym.


i work as a research engineer, with an interest in: foundational models, policy learning, medical ai, and programming. if you're curious about my current fixations, skim the blog.

i like making things.

much of my stuff is educational, but i'm shifting focus to practical applications.

  • this website, including my blog
  • exploring the limitations of llm-as-a-judge
  • llmcontext (fork of original), a context window pressure tester of open llms
  • alphafour , scratch implementation of alphazero for connect four in pure pytorch
  • a framework for super-resolution of clinical 4d flow mri. paper.

i like open source.

these are my favorite, some of which i contribute to.
