Paul Knott
Researcher
Paul’s research interests include AI risks in short and medium timelines, macrostrategy, and anything to do with parallel universes. He did a PhD in quantum physics at the University of Leeds, and has completed three postdocs researching at the interface of AI and quantum physics.
Tristan Cook
Senior Community & Engagement Manager
Tristan leads the Community & Engagement team. He previously worked on research at CLR, primarily on s-risk macrostrategy. Previously, Tristan studied mathematics at the University of Cambridge and the University of Warwick
Winston Oswald-Drummond
Community Manager
Winston does s-risk community building at CLR. His work includes running CLR's S-risk Intro Fellowship, giving talks, and hosting meetups. Previously he worked at the Center for Reducing Suffering (CRS), where he did research, ops, and community building.
Amrit Sidhu-Brar
Operations Advisor
After four years in our operations team, Amrit has stepped back to an advisory role as he transitions out of CLR and hands over to Harry Day. Previously he studied medieval languages at the University of Cambridge, and ran operations at a tech startup.
