Philippe Rivet is a Canadian electrical engineer based in Toronto, Ontario, who has pursued applied technical AI alignment research. He received an NSERC Undergraduate Student Research Award during his undergraduate studies and later completed studies related to machine learning and AI safety, including coursework from Dan Hendryck's ML Safety program. His GitHub profile reflects interests in evolutionary computing, reinforcement learning, interpretability, and AI alignment. He has described his path as a "costly attempt at AI safety research" and has since considered earning-to-give as an alternative contribution to effective altruism. He received a $10,000 grant in support of applied technical AI alignment research. He is active in the effective altruism community, having published a post on the EA Forum titled "The Highly Sensitive EA," and maintains interests in contemplative practice and philosophy.

Independent researcher at the Institute of Computer Science (ICC), CONICET‑UBA, with an Electrical Engineering PhD from Stanford University; her main research area is machine learning applied to speech and language processing.

Alexis Carlier is the co-founder and CEO of Asymmetric Security, an AI-native digital forensics and incident response company that emerged from stealth in early 2026 with $4.2M in pre-seed funding. He was previously part of the founding team at the Centre for the Governance of AI (GovAI), where he served as Head of Strategy and contributed to the organization's transition from Oxford to an independent nonprofit. He also led AI security programs at RAND and the University of Oxford. Carlier holds a Master's degree in Economics from the Toulouse School of Economics. He received a Long-Term Future Fund grant in 2020 to survey leading AI safety and governance researchers on their beliefs about AI existential risk scenarios, work that was later published on the EA Forum and LessWrong co-authored with Sam Clarke and Jonas Schuett. He has also co-authored academic papers on AI governance topics including AI ethics board design and frontier AI regulation.

Neil Crawford is a PhD student in Logic and Philosophy of Science at UC Irvine whose research focuses on evolutionary game theory and its implications for AI safety. He has been involved in the Effective Altruism community since his undergraduate studies at the London School of Economics (2018) and has been a central figure in building the AI safety community at UC Irvine. He organized AI Alignment Irvine (AIAI), facilitating weekly alignment reading groups and AI safety dinners, and helped recruit a core group of PhD students engaged in AI alignment research. He also facilitated the Arete Fellowship at UCI, an 8-week introduction to Effective Altruism, and co-organized EA at UC Irvine. He has received grants from EA Funds (Long-Term Future Fund) to support his organizing work, including a stipend for running AIAI and funding for AI safety dinners. He is listed as a member of the AI Safety Community Researchers group at the Future of Life Institute.

Lead Researcher at Saving Humanity from Homo Sapiens, investigating how humanity can achieve very-long-term sustainability and a flourishing long-term future while avoiding global catastrophic and existential risks.

Matthias Georg Mayer is an independent researcher and mathematician working in AI safety, with a focus on agent foundations and providing formal guarantees for the safety of AI systems. He was a 2025 Alumni Fellow at Principles of Intelligence (PIBBSS), where he worked on theoretical alignment research. His earlier work centered on structural independence, a generalization of d-separation concepts applied to structural causal models (also known as Finite Factored Sets), and he co-authored the paper "Factored space models: Towards causality between levels of abstraction" (arXiv 2412.02579, December 2024) alongside Scott Garrabrant, Magdalena Wache, Leon Lang, Sam Eisenstat, and Holger Dell. More recently his interests have shifted toward the Learning Theoretic Agenda developed by Vanessa Kosoy, with particular focus on Infrabayesian-Physicalism as a means to address embedded agency. He has received funding from the Long-Term Future Fund (LTFF) to research framing computational systems in ways that surface meaningful concepts. He participates in the AI alignment community through the Alignment Forum and LessWrong under the handle matthias-g-mayer.

Remmelt Ellen is a Dutch AI safety organizer and researcher based in Amsterdam, Netherlands. He co-founded Effective Altruism Netherlands in 2017 and co-launched AI Safety Camp (AISC) in 2018, serving as an organizer for nearly every edition of the program. At AISC he oversees program design and currently coordinates Stop/Pause AI projects, working to onboard initiatives that advocate for halting or pausing unsafe AI development. His research focuses on AGI safety impossibility arguments, including formal reasoning on why advanced AI systems cannot be reliably controlled, developed in collaboration with a former Pentagon engineer. He authored the book "Artificial Bodies: How Machines Replace People" (2024), a critical examination of how Big Tech corporations create exploitative systems that consume human resources and disrupt ecological balance. He has received grants from the Long-Term Future Fund to support AI Safety Camp's virtual and in-person programs.
