Ondrej Bohdal

I'm a senior machine learning researcher at Samsung Research, where I focus on personalization of generative AI models. Before joining Samsung, I was a postdoctoral researcher at the University of Edinburgh, working on topics such as multimodal large language models, diffusion models, fairness, uncertainty calibration and out-of-distribution generalization.

I did my PhD on Meta-Learning Algorithms and Applications at the University of Edinburgh, advised by Timothy Hospedales. I was a research intern at Samsung AI Center, Cambridge and Amazon Web Services, Berlin, and also did part of my studies at the Alan Turing Institute in London.

Misc

I often competed and won prizes in various hackathons, including Algothon (quant finance hackathon), QuHackEd (quantum computing hackathon), Data Open (datathon organized by Citadel - I even participated in the Championship), Hack the Burgh and many others. An overview of some of the projects I worked on is available on my Devpost profile, and there are also articles about my teams here and here.

During my high school I very successfully participated in many competitions in Mathematics, Physics and Informatics, in particular the subject Olympiads, correspondence seminars and various team competitions. Most notably I represented Slovakia at the Middle European Mathematical Olympiad in Dresden, Germany in 2014.
