School of Architecture and Civil Engineering

Prof. Dr.-Ing. Heather Kaths

Heather Kaths received a Bachelor of Science in Civil Engineering with a focus on Transportation Engineering from the University of Calgary in Canada.  During her studies, she took part in an international student exchange at the University of Stuttgart in Germany. It was in Stuttgart that she first came into contact with sustainable mobility topics, both personally and within the study programme.

Motivated by this exchange, Ms. Kaths pursued a Master of Science in Transportation Systems at the Technical University of Munich (TUM). Here, she focussed on demand management and whenever possible, cycling and walking. A following research associate position at the Chair of Traffic Engineering and Control at the TUM allowed Ms. Kaths to focus on bicycle traffic from a modelling and simulation perspective, complete her doctoral dissertation on this topic and build a research group about urban traffic simulation.

As of April 2021, Heather Kaths has led the new Chair of Bicycle Traffic. With regard to research, she is passionate about data, behaviour modelling, and traffic simulation. In teaching, she aims to bring an international perspective into educating the cycling experts of tomorrow.
