Anish participated in the MATS Summer 2024 Cohort under the mentorship of Christian Schroeder de Witt (University of Oxford). He published "Efficient Dictionary Learning with Switch Sparse Autoencoders" (https://arxiv.org/abs/2410.08201), a novel SAE architecture aimed at reducing the compute cost of training SAEs. He is currently pursuing an undergraduate degree in Computer Science at MIT, where he is grateful to be advised by Max Tegmark.

Can is currently developing SAE Bench, an evaluation suite for interpretability techniques, in collaboration with Neel Nanda, Adam Karvonen and Decode Research. They launched the project during the MATS 2024 summer cohort. Can, a physics graduate, transitioned to language model interpretability through ARENA and AI Safety Camp. His previous work on Sparse Feature Circuits and Edge Attribution Patching focused on circuit discovery in language models.

As part of MATS 6.0 supervised by CHAI’s Micah Carroll, Constantin and his collaborators demonstrated that targeted manipulation and deception emerge in LLMs trained on user rather than annotator feedback. His MATS stream’s paper was accepted as an oral contribution at the SATA workshop and a spotlight at the SoLaR workshop, both at NeurIPS.

Constantin's experience at MATS led to his role as the first technical staff member at Haize Labs. There, he focuses on LLM automated red teaming and jailbreak protection supporting labs such as Anthropic, OpenAI, and AI21.

Prior to MATS, Constantin completed a PhD applying machine learning to particle physics and worked as a machine learning consultant at McKinsey.

David participated in the Summer 2024 MATS cohort under the mentorship of Lisa Thiergart of MIRI's technical governance team, during which he developed forecasts of US-China relations in the run-up to transformative AI. His interests include international relations, history, wargames, and systems design. David has a BS in Symbolic Systems from Stanford University and a professional background in video game design.

Evžen took part in the winter and summer MATS cohorts in 2024. He is interested in model internals work, ranging from mechanistic interpretability to approaches on a higher level of abstraction. With his colleagues and under the supervision of Alex Turner, he worked on Gradient routing (https://arxiv.org/abs/2410.04332). He is now writing his master thesis at ETH Zurich under the supervision of Florian Tramèr.

Guang-Yuan participated in the MATS 6.0 Cohort in summer 2024, collaborating with Steven Basart and Andy Zou at CAIS. His AI safety research focuses on robustness and interpretability, with the goal of enhancing the reliability and transparency of AI systems across diverse environments and modalities.

Hantao worked on developmental interpretability and model auditing under the mentorship of Evan Hubinger during the 2024 MATS summer cohort remotely. He analyzed the shift of interpretable features before/after finetuning, thereby developing a method to improve model auditing. Before MATS, Hantao is an undergraduate student at Peking University and a visiting student at PAIR Lab. He is now continuing his research in MATS extension to gain a deeper insight into interpretability and alignment.

Jiaxin was a MATS 6.0 scholar under the mentorship of Akbir Khan, Ethan Perez, and Buck Shlegeris. During MATS, he studied unintended AI deception that emerges from RLHF and low-stakes AI Control over scheming AI. He is currently a Master's student at Tsinghua University.

As part of MATS 6.0, Kai worked on measuring instrumental self-reasoning (a precursor to deceptive alignment) in frontier models under the mentorship of David Lindner. Prior to MATS, he explored variants of Goodhart's Law and evaluating llm's ability to self-correct. As of October 2024, he is finishing a masters at Stanford University studying math and computer science while completing the MATS extension phase.

Lucie a Program Manager at FPTPEC (French government, PECC), where she organizes track 2 dialogues on the international governance of AI. She previously worked in software engineering and cryptocurrency, and she is considering switching to a more technical role in 2025. During MATS, she worked with Philp Tomei and Matija Franklin on exploring the interplay between macroeconomic forces and frontier AI labs, specifically how the investors of frontier labs influence the lab's behavior.

Marcus took part in Micah Carroll's MATS summer 2024 stream where he worked on exploring annotator vulnerabilities and the tendency of LLMs to influence human preferences. This resulted in the paper "Targeted Manipulation and Deception Emerge in LLMs Trained on User Feedback". Previously Marcus was doing independent alignment research on preference modeling and RL.

His main focus is clarifying substrate-flexible risk and its implications for interpretability.

Michael worked on mechanistic interpretability with Lee Sharkey during MATS 6.0. During MATS, he developed methods to decompile more interpretable transformer architectures, used Meta-SAEs to find interpretable features within SAE latents, and applied information-theoretic approaches like minimal description length to guide the selection of SAE hyperparameters and architecture.
