My research interest concerns coordinated planning of infrastructure maintenance and traffic, primarily for railways. I mostly use methods from applied mathematics, operations research, optimization, scheduling algorithms and sometimes constraint programming – if possible with a link to transport economy and socioeconomic valuation methods. I share my work time between Linköping University and the Swedish Road and Transport Research Institute (VTI), where I belong to the unit Transport analytics and logistics (TAL) in Stockholm. At LiU I belong to the unit for Public Transport and Railways at Campus Norrköping, where I primarily conduct various research projects and teach in a few courses.
My main private interest is music. Previously I have been singing in, and conducted different choirs, but nowadays I focus primarily on playing cello in a string quartet.
