Caleb Rak is an operations professional in the AI safety and effective altruism community. He grew up in Norwich, Connecticut and attended Norwich Free Academy, where he was a 2017 National Merit Scholarship Finalist. He went on to Harvard University, graduating with a degree in Comparative Literature and Linguistics; his senior thesis was titled "Translating Zhou Zuoren: The Vernacular Essay and the Individual." After graduating, he became involved in EA community-building through roles at SPARC (a rationality and EA summer program for high school students) and Canopy Retreats (an organization supporting logistics for EA community events).

Aysja Johnson is an AI safety researcher and policy analyst focused on AI lab scaling policies and responsible scaling frameworks. She holds a background in cognitive science, having completed undergraduate studies in Mathematics at UC Berkeley and graduate work in NYU's Computation and Cognition Lab under Todd Gureckis, where she studied human sense-making, open-ended reasoning, and human-machine intelligence. She was hired as a Research Analyst at AI Impacts in 2022, selected from over 250 applicants, contributing research on comparative cognition and technology adoption patterns relevant to AI risk. In 2023 she was a PIBBSS Summer Fellow, working on a project titled 'Towards a Science of Abstraction' exploring why natural abstractions are favored by agents and what this implies for AI alignment. She received a Long-Term Future Fund stipend for 1.5 years to conduct a thorough investigation and analysis of AI lab scaling policies, and has published critical analyses on LessWrong arguing that current responsible scaling policies lack rigor, fail to specify measurable evidence thresholds, and that behavioral evaluations alone are insufficient for safety assurance. She is active on LessWrong under the handle 'aysja' and has co-authored posts on AI lab governance topics including OpenAI's non-disparagement practices.

Yuxiao Li is an AI safety and mechanistic interpretability researcher currently based in Bilbao, Spain, where she is a postdoctoral researcher at the Basque Center for Applied Mathematics (BCAM). She holds a PhD in Computer and Information Sciences from Tsinghua University (2018-2023). Her research focuses on understanding the internal representations of large language models through techniques such as sparse autoencoders, variational inference, and geometric analysis of feature spaces. She was previously affiliated with MIT's Tegmark group and the Beneficial AI Foundation, where she was first author on "The Geometry of Concepts: Sparse Autoencoder Feature Structure" (arXiv 2024), a study of how concepts are geometrically organized in LLM activations. She has also participated in the ML Alignment & Theory Scholars (MATS) program and the Supervised Program for Alignment Research (SPAR), contributing multi-part research on structured priors and block-diagonal geometry in language model activations. She currently serves as a mentor in the Algoverse AI Safety Fellowship and has received independent research funding for inference-based AI interpretability work.

Sviatoslav (Slava) Chalnev is an AI researcher based in Sydney, Australia, with a background in mechanistic interpretability and AI safety. He studied at The Australian National University and subsequently pursued independent interpretability research funded by two Long-Term Future Fund stipends totaling $75,000, focused on mechanistic interpretability methods and open-source tooling. He participated in the MATS 6.0 program under Arthur Conmy, resulting in the paper "Improving Steering Vectors by Targeting Sparse Autoencoder Features" (arXiv:2411.02193, 2024), which introduced SAE-Targeted Steering (SAE-TS), a method for constructing steering vectors that target specific sparse autoencoder features while minimizing unintended side effects. He also co-authored "A Single Direction of Truth" (arXiv:2507.23221, 2025), demonstrating that a linear probe on an observer model's residual stream can detect and causally steer contextual hallucinations in language models. More recently, Chalnev co-founded Integuide, an AI startup building tools to capture and disseminate expert technician knowledge, which was part of the Startmate Winter 2025 accelerator cohort.

Tomislav Kurtovic (Tomislav Kurtović) is a researcher and Computer Vision PhD candidate at the Faculty of Electrical Engineering and Computing (FER), University of Zagreb, Croatia.

Hoagy Cunningham is an AI safety researcher currently working at Anthropic, where he has contributed to both interpretability and safeguards research. He holds a 2:1 in Politics, Philosophy and Economics from The Queen's College, Oxford, and earlier in his career worked as a researcher at Full Fact, the UK fact-checking charity, and as an economist. He became a SERI MATS scholar under Lee Sharkey and is the lead author of "Sparse Autoencoders Find Highly Interpretable Features in Language Models" (ICLR 2024), a foundational paper demonstrating that sparse autoencoders can recover monosemantic, interpretable features from language model activations. This work was independently developed in parallel with similar research published by Anthropic and generated significant excitement in the mechanistic interpretability community. He received Long-Term Future Fund grants supporting his sparse coding research and work on preventing steganography in interpretable representations. At Anthropic, he has contributed to research on scaling monosemanticity, constitutional classifiers for jailbreak defense, and auditing language models for hidden objectives.
