Johannes C. Mayer is an independent AI alignment researcher and game developer who has dedicated his career to addressing AI existential risk. He participates in the AI safety research community through LessWrong and the AI Alignment Forum, where he has published over 76 posts on topics including structural approaches to alignment, computational models of intelligence, and world model interpretability. He completed the MATS Summer 2022 cohort under the mentorship of Evan Hubinger, and has served as a mentor for the Supervised Program for Alignment Research (SPAR) at UC Berkeley. His research agenda focuses on translating intuitive concepts such as goals, wanting, and abilities into formal computational frameworks, and on constraining AI reasoning processes structurally rather than purely specifying outcome-level objectives. He received a grant from the Long-Term Future Fund to pursue this research on turning intuitions about intelligence into concepts applicable to computational systems.

Alexander Matt Turner, known online as TurnTrout, is a research scientist at Google DeepMind on the Scalable Alignment team, based in Berkeley, California. He earned his PhD in computer science from Oregon State University (2016–2022) under advisor Prasad Tadepalli, followed by a postdoc at UC Berkeley's Center for Human-Compatible AI (CHAI) from 2022 to 2023. His research spans several key areas of AI alignment: he developed Attainable Utility Preservation (AUP), a framework for low-impact AI; proved mathematically that optimal policies tend to seek power, published as a NeurIPS 2021 spotlight paper; co-developed shard theory (with Quintin Pope), a framework modeling AI and human values as situationally activated goal components; and pioneered activation engineering and steering vectors for controlling model behavior at inference time. At Google DeepMind, his current work includes consistency training to reduce sycophancy and jailbreaks in Gemini models. He is also a MATS mentor through his Team Shard program, supporting junior alignment researchers.

Jamie Bernardi (full name James Bernardi) is an AI safety researcher and policy professional based in London, UK. He studied Physical Natural Sciences (MSci Physics) at St John's College, Cambridge (2015-2019), then worked as a machine learning engineer at Audio Analytic (2019-2021), a sound recognition company later acquired by Meta. In 2021-2022 he worked as an independent researcher in collaboration with Oxford's Future of Humanity Institute, designing a pessimistic reinforcement learning algorithm intended to improve AI safety by having the system ask for human help when uncertain about potential harms. He co-founded BlueDot Impact in August 2022, an education charity running the AI Safety Fundamentals courses that have introduced thousands of ML engineers, policymakers, and students to AI safety and governance. After serving as a GovAI Winter Fellow and IAPS Fellow focused on AI policy and societal adaptation to advanced AI, he joined the UK AI Security Institute (AISI), where he works on strategic awareness. He has contributed to UK policymaking on AI regulation and international AI governance efforts.
