Researcher at VTI – The Swedish National Road and Transport Research Institute and LiU – Linköping University. I combine transport economics (socio‑economic evaluation, cost–benefit analysis, life‑cycle costing) with mathematical optimisation for capacity allocation, timetabling, maintenance planning and passenger information in public transport and railways.
I hold an engineering diploma in Computer Science and Applied Mathematics from Grenoble INP (Ensimag), an M.Sc. in Computer Science and Engineering from KTH – Royal Institute of Technology, and a PhD in Infra‑Informatics from Linköping University. I’m also active in linguistics, photography, and open‑source (notably Wikimedia).
