Milot’s venture into establishing his own lab is incredibly excitinge. I highly recommend to join Milot on his mission to advance molecular biology through open-source bioinformatics.
My time in @martinsteinegger.bsky.social's group is ending, but I’m staying in Korea to build a lab at Sungkyunkwan University School of Medicine. If you or someone you know is interested in molecular machine learning and open-source bioinformatics, please reach out. I am hiring!
