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 an Assistant Professor (Lecturer in the Australian nomenclature) leading the Share research line in the TransportLab, School of Civil Engineering at the University of Sydney.

I got my Ph.D. at Universidad de Chile under the supervision of Professor Sergio Jara-Díaz (2019), and did a postdoc at TU Delft supervised by Prof. Javier Alonso-Mora. Before that, I got my degree as Engineer and as an M.Sc. in Transportation Engineering at Universidad de Chile (2014). I have also worked as a researcher in Universidad de O’Higgins, and as an external lecturer in different courses at Universidad de Chile and Universidad Federico Santa María.
