I'm generally interested in the following topics:
- Transportation network design problems
- Road pricing
- Evolutionary algorithms
- Surrogate-based optimization
- Motor vehicle emissions and the related public health impacts
- Traffic rationing
- Parking management
- Transportation equity
I'm currently working on:
- Transit network design problems with a focus on equity issues
- Non-pricing strategies for solving parking scarcity problems
- Predictive analytics applied to e-scooter demand estimation
In the past I worked a bit on freight-related topics, but I'm not currently involved on any freight projects. Next, a list of publications, presentations, and working papers.
