About Me

I am a Postdoctoral Researcher at the SIAS Group of the University of Amsterdam.

I was previously a PhD Candidate at the Civic AI Lab, and will defend my thesis in February, 2026.

In my research, I use Machine Learning to design inclusive, accessible and sustainable cities.

My current focus is on using Reinforcement Learning to explore the trade-off between utility and equity/fairness when designing public transport networks.

In the near future, I would like to investigate how urban populations would adapt to such changes in a city's public transport networks.

My goal is to create a multi-agent framework that helps to envision alternative urban designs and their evolution in time.

Sounds interesting? Then please, get in touch!
