perception and world models focusing on post training to develop the reasoning that connects sensing to action particularly in robotic surgery and other high stakes domains i am the author of the craft of post training a practical guide for ai engineers and developers no starch press 2026 now shipping on amazon differentiable photon transport volume i foundations and computational modeling of infectious disease elsevier 2023 as well as a growing body of research i attended the university of oxford for my undergraduate studies graduating with a distinction 1st class and returned there for my graduate studies i also hold degrees from cardiff and robert gordon university aberdeen and have studied at the university of leiden under an erasmus programme today i am board certified in public health a fellow of the royal society for public health and a member of several other learned societies i have also been elected a senior member of ieee where i am a member of the embs technical committee on standards and the embs technical committee on biomedical and health informatics i am also a visiting thesis supervisor for students on the data science track of the mathematics programme at the budapest university of technology and economics depending on whom you ask i have been accused of having invented agentic ai this is not entirely true as the concept is much older norvig and russell used it in 1995 but my description of what eventually became agentic ai is one of the earliest ones my work also spans robotics simulation and reinforcement learning with tamás földi i am a principal investigator of the asset factory blueprint an open source reference implementation from hcltech s robotics intelligence coe for turning photographs scans and cad into reproducible openusd assets and reinforcement learning environments i am also one of the creators of ceres an open source application that turns every meta quest headset into a high quality capture device for egocentric hand object interaction data as part of my service to the profession i ve been a reviewer for joss frontiers in immunology and frontiers in medicine between 2022 and 2023 i served virginia as a member of the medical reserve corps and currently serve in both the rocky mountain mrc of denver and colorado s radiation response mrc i was also part of the covid 19 healthcare coalition and the covid tracking project you can find a list of my publications here my work on covid 19 has been featured in the media i also write on various topics as the fancy strikes you can peruse my notebook here key

spent my formative years in england but have called the netherlands germany belgium austria and the united states home at various points in my life since 2020 i ve been living in the united states where i am a permanent resident in my free time i enjoy reading mostly cold war history and classical greek drama cooking with not a lot of success and renaissance polyphony esp thomas tallis and orlando di lasso i m credited for a somewhat pretty sequence of integers called jellyfish heart numbers oeis a344856 which i discovered in 2020 while doing something that has nothing at all to do with my day job i ve lived with neuromyelitis optica since 2015 which landed me in a wheelchair but never slowed me down it did however give my work a personal stake to find ways in which machine intelligence and sensing can expand what people can do see and perceive on their own terms my experience of spinal cord injury has shaped my interest in ai not as an academic pursuit for its own sake but as a means of extending human agency independence and capability in what little is left of my free time i m an adaptive multisport athlete competing in wheelchair rugby adaptive rowing category pr1 and the skierg category sit2 in the latter i currently hold the world records for 100m 500m 1 000m 2 000m 6 000m 10 000m 21 097m and 42 195m distances and the 60 minutes time i occasionally rant and whine about my forays in the world of adaptive exercise and my attempts at doing so in a mostly science based manner pronunciation guide my last name rhymes with chick fil a chris von csefalvay
