“One must still have chaos in oneself to be able to give birth to a dancing star.” — Friedrich Nietzsche

Isotta Magistrali

MSc Computer Science, ETH Zürich · MATS Scholar

I'm a second-year Master's student in Computer Science at ETH Zürich. I carried out my Master's thesis at MIT and I'm currently a MATS scholar in the LawZero stream, the AI safety organization founded by Yoshua Bengio. My research sits at the intersection of behaviour, interpretability and alignment: I study how human cognition, behaviour and psychology shape modern AI models and agents, and how these agents reason and act within the complex frameworks that are second nature to humans yet remain largely unexplored for AI. I aim to develop systems whose internal reasoning we can interpret and whose behaviour stays reliably aligned with deeply human social processes, while ensuring an efficient and transparent use of resources.

I received my Bachelor's degree in Mathematical and Computing Sciences for Artificial Intelligence from Bocconi University.

I'm always happy to chat about research and open to collaborations, so feel free to reach out!

Other interests: sports, music, art, philosophy

Aligned Alone, Misaligned Together: Forecasting Adversarial Capture in LLM Agent Populations

Isotta Magistrali, Chen Shani

A committed adversarial minority can drive a population of LLM agents into a collective decision none of its members would make alone; we show this is predictable in advance, only partly defendable, and reversible once the adversaries are removed.

Causal importance in CoT reasoning

Does the Model Know Which Steps Matter? Probing Causal Importance in Chain-of-Thought Reasoning

Isotta Magistrali, Mrinmaya Sachan, Alessandro Stolfo

Probing whether large language models can identify which intermediate steps causally drive their final answer in chain-of-thought reasoning.

Subliminal Signals in Preference Labels

Even in a highly constrained setting where a neutral student model generates unbiased completions, a biased judge can transmit behavioural traits to it through binary preference labels alone.

Nudged product listing seen by a web subagent
Master's thesis · ETH Zürich & MIT Media Lab · 2026 Publication coming soon

Cascading Nudges: Controlled Interventions in Hierarchical Web Agents

A nudge seen by a single subagent on a real web page can cascade into the final output of a hierarchical computer-use system, showing the system is only as robust as the subagents that read the web, despite the stronger model that controls them.

Completed as my Master's thesis, supervised by Manuel Cherep, Nikhil Singh, Prof. Pattie Maes, Frédéric Berdoz and Prof. Roger Wattenhofer.
