Summary: Machine learning looks for the model that best fits the existing data. To better understand this high-dimensional optimization problem, I am studying the behavior of optimization algorithms on random functions.

Summary: Nowadays, online stores often use AIs to set their prices. Could these AIs form cartels? And how could we detect and prevent it?
Topic/
Summary: We aim to advance computational techniques for hierarchal optimization problems and games. Our methods will be applied to energy systems and computational imaging.

Summary: AI is increasingly being used in public spaces (for instance, as part of smart city schemes). I am using simulations to study the (possibly unintended) effects of this development.

Summary: Reinforcement learning (RL) algorithms are used to train AIs like ChatGPT. My dissertation investigates the convergence of RL algorithms to establish theoretical guarantees for their application.
