Personal Information

My professional career was devoted to transportation planning and modeling in the Chicago Region. I worked for the Chicago MPO (CATS/CMAP) from 1985 until 2015. In 2016, I joined the Transportation Center at Northwestern University. I also serve on several TRB technical oversight panels.

In May 2016, I was invited to address a plenary session at TRB's Innovations in Travel Modeling Conference held in Denver, CO. My chosen topic was: A historical perspective of innovations in travel modeling.
