Research Interests

My research interests lie in the broad area of ​​algorithm design and engineering. In the frame of my MSc Thesis I developed a new time-dependent model for multimodal public transit, along with two algorithms for computing optimal multimodal journeys for either a single criterion (earliest arrivals) or two criteria (earliest arrival and number of transfers).

As a Phd student I want to explore new algorithmic problems. Recently, I have become particularly interested in network creation games, and I'm excited to dive in this field further.
