I research complex social systems: urban mobility. Congested, urban multimodal networks used by millions of agents to reach their destinations and leaving huge sets of mobility traces ready to be applied for modelling, optimization, understanding and control. Full CV

Currently, I run the ERC Starting Grant COeXISTENCE where I bridge between ML and transportation - we simulate how intelligent machines compete with humans for limited urban resources (space) and what can we expect. See details and vacancies here I am Assistant Professor in the Faculty of Mathematics and Computer Science of Jagiellonian University in Krakow (Poland) with the Group of Machine Learning Research GMUM. I run the NCN Opus Grant on Shared Mobility in the pandemic times.

Before, I worked (2019-2021) with prof. Oded Cats at TU Delft in his ERC Starting Grant Critical MaaS. I modelled two-sided mobility platforms, specifcally focusing on ride-pooling (ExMAS) and agent-based simulator for Uber-like systems (MaaSSim). I did PhD at Cracow University of Technology with an excellent goup of prof. Andrzej Szarata and working closely with Guido Gentile from La Sapienza on non-equilibrium dynamic traffic assignment. In the interdisciplinary field of urban mobility I did research which can be classified as:

  • model estimation, optimization, system control, network design;
  • agent-based simulation, game-theory, network science, stochastic simulation, epidemic modelling;
  • machine learning, spatial analysis, big data analysis, pattern recognition, unsupervised learning;
  • behavioural modelling, economic discrete choice models, policy, sustainability.

I run the seminar on Complex Social Systems (transport is one of them) at Jagiellonian University - materials and papers are on my github


news

Jan 2, 2023 This week we present two posters on the TRB in Washington. Farnoud presents how to simulate market entry of Uber and Usman (or me on his behalf) presents what we found out about complexity of ride-pooling problems - see you at our sessions in DC!
Dec 2, 2022 Congratulations Arkadiusz Drabicki for winning the Transport Research Arena Young Researchers Competition in the category Crossmodality! Arek was awarded for his work on Modelling the impacts of real-time crowding information in public transport in collaboration with prof. Oded Cats, Achille Fonzone, Andrzej Szarata and myself - good job Arek.
Nov 11, 2022 Good job Jaime! Our paper (with Oded Cats) on the relation between spatial structure of the demand patterns and the shareability is now published in Transportmetrica:A
Nov 8, 2022 Long overdue, but I will present my work on hyper-pool in CASPT - believe it or not, but we ubmitted it before the pandemic (Feb 2020) and the conference comes only now, in Tel-Aviv. See slides and the pre-print
Sep 9, 2022 We launched collaboration on Network-Science with the group of prof. Rob Kooij to exploit how networks shape the ride-pooling problems. Today I gave a seminar for his group in Delft.
Aug 5, 2022 👏 1st Aug is a relief day for all transport-people, so it was for us, we can be happy with out TRB submissions, kudos to all👏:
  • 🧨 Farnoud Ghasemi made an intiguing ABM simulations of Uber rise and fall: https://arxiv.org/abs/2208.02496
  • 🧨 Usman Akhtar explored when and why the ride-pooling calculations explode: https://arxiv.org/abs/2208.02504
moreover:
  • 🧨 Olha Shulika is closing up her Post-Pandemic Ride Pooling Review and
  • 🧨 Michal Bujak lately got accepted for Complex Networks conference with his probabilistic ride-pooling: https://arxiv.org/abs/2206.12259
That is not a bad outcome for the first 12 months of our group - let’s take some well-deserved rest: 🏝⛱🏝⛱🏝⛱🏝⛱
