Karen was appointed as Secretary General of POLIS in September 2014, after havening been the Network's Research Director. Since then she's leading the European network of cities and regions on urban transport innovation. For over 30 years already, members have been working together to develop and deploy sustainable and innovative urban mobility solutions for the city of today and tomorrow. Karen is certain that what was originally the preserve of the public sector, namely the provision of mobility services, is now also increasingly becoming an area in which private players are becoming active. Over the past few years, this has led to cities having to rethink and reinvent their role. With her, we explored smart ways to align innovations from industry with public policy goals.
