I am a Lecturer (US Assistant Professor equivalent) at the Gatsby Unit, University College London. Previously, I was an Applied Scientist at the AGI Foundations Lab at Amazon, where I worked on fundamental research on the theory and science of scaling large language models. I earned my Ph.D. from the International Max Planck Research School for Intelligent Systems with Debarghya Ghoshdastidar at the Theoretical Foundations of Artificial Intelligence group, Technical University of Munich, and Ulrike von Luxburg at the Theory of Machine Learning group, University of Tuebingen. My thesis received the Wilhelm Schickard Dissertation Award (Outstanding Dissertation). During my Ph.D., I also spent 6 months at the Causality Lab of Amazon Research.

My research aims to develop efficient, reliable, and trustworthy machine learning models by understanding the theoretical foundations of deep learning and causal learning. Deep learning theory and causality present some of the most fascinating challenges in modern machine learning. Classical theories of statistical learning and optimization often struggle to explain the empirical success of deep learning algorithms or even provide reliable guidance on their behaviour. As models continue to scale to unprecedented levels, revealing emergent abilities, we need fundamentally new theories to explain their behavior. To tackle some of these questions, my research aims to i) develop a unified theory of scaling and ii) understand the learning dynamics and generalization in deep learning. Meanwhile, Causality remains in its nascency, with formal mechanisms still emerging. My research will address open problems in causality, including establishing robust formalisms for causal reasoning and developing frameworks to evaluate causal models.
