About me

I am Andrés Fielbaum, Mathematical Engineer and Ph.D. in Systems Engineering. My main fields of research are public transport, transportation networks, new transportation technologies, and transport-related algorithms. I am a Senior Lecturer (tenured) leading the Share research line in the TransportLab, School of Civil Engineering at the University of Sydney.
My research combines mathematical modelling, optimisation, and transport engineering to study the design and operation of public transport and emerging mobility systems. I am an ARC DECRA Fellow and serve as Associate Editor of Transportation Research Part B: Methodological and the Journal of Intelligent Transportation Systems. Before joining the University of Sydney in 2023, I received my Ph.D. from Universidad de Chile in 2019, supervised by Professor Sergio Jara-Díaz, and subsequently conducted postdoctoral research at TU Delft with Professor Javier Alonso-Mora.
