Nathan Ranchin

I'm Nathan, an MSc student in Computer Science at ETH Zürich, currently interning at Liquid AI on the post-training team. I focus on LLM efficiency: compression, constrained decoding, and post-training techniques.

Previously, I was a research intern at the SwissAI Initiative (ETH AI Center) working on the Apertus project, and a research assistant at EPFL's DLAB, where I co-authored papers at NeurIPS 2025 and ICML 2025.
