Paul Colognese is an AI safety researcher based in the United Kingdom, focused on understanding how AI systems represent and self-reflect on their goals and beliefs. He holds a PhD in Mathematics (Geometry, Topology, and Dynamical Systems) from the University of Warwick, where he researched translation surfaces under the supervision of Professor Mark Pollicott. His AI safety work includes building safety evaluations for Anthropic and the UK AI Security Institute, including control and sabotage evaluations that measure whether deployed AI agents could undermine safety systems. He has conducted AI threat modeling on catastrophic risk scenarios and carried out interpretability research in which he demonstrated the ability to detect an AI system's objectives through technical analysis. He participated in the MATS research program mentored by Evan Hubinger at Anthropic. He founded the London Initiative for Safe AI, a UK-based research center, and serves as AI Alignment Lead at the Center for the Study of Apparent Selves. He is active on LessWrong and the Alignment Forum, and participated in AI Safety Camp (AISC9) working on detecting agentic AI objectives via interpretability methods.

Sam F. Brown is an independent AI alignment researcher based in Oxford, UK. He has a background in physics and programming, and previously worked at a climate technology startup before pivoting to full-time alignment research. He has received two grants from the EA Long-Term Future Fund: an initial six-month grant (approximately £40,000) for research on goal-inference and choice-maximisation, and a subsequent twelve-month grant ($82,298) to research technical approaches to value lock-in and minimal paternalism. His work explores empowerment-based alignment — the idea of maximising humans' capacity to reach diverse future outcomes rather than inferring and locking in specific human values. He has published research essays on LessWrong and the EA Forum, including "The Empowerment of Others" and "Questions about Value Lock-in, Paternalism, and Empowerment". He is connected to the Oxford rationalist and EA community and works from spaces including Trajan House, the Centre for Effective Altruism's Oxford building.

Co-director of the Cambridge AI Safety Hub, working on AI safety fieldbuilding in Cambridge, UK. Previously a political science PhD candidate at SUNY Stony Brook, with experience in research and teaching before moving full-time into AI safety.

Gavin J. Taylor is a researcher affiliated with the Institute for Globally Distributed Open Research and Education (IGDORE), based in São Carlos, Brazil. He studied at the University of Queensland and consults for Resonant Health Inc., a company developing a medical device using low-dose microwaves for antiviral applications. His research focuses on physical virology, microwave viral inactivation, optical simulations, and Micro-CT imaging. In 2020, he received a $30,000 grant from the Long-Term Future Fund to conduct a computational study on using a light-to-vibrations (L2V) mechanism as a targeted antiviral, with the aim of identifying viruses susceptible to inactivation via resonant vibrational frequencies. He has published peer-reviewed work including a 2024 paper in Applied Physics Reviews on virus inactivation by matching vibrational resonance, and a 2023 comment in Viruses correcting mathematical errors in SARS-CoV-2 microwave inactivation research. His work is recognized as providing a mathematical model for predicting microwave frequencies effective for viral inactivation.
