3. Who am I

I am an engineer-economist and planner, an urbanist and philosopher of the built environment.  I have worked on a variety of large scale urban and regional developments, policy and planning studies, and civil infrastructure systems analysis throughout the United States and abroad, and written and taught on these subjects.  I undertake consulting assignments in support of public-sector and private clients, formerly through the MATRIX group LLC, a firm I founded in 1985, and now as an independent contractor.  I formerly held senior management positions with PRC Engineering, Inc.; PRC Nigeria, Ltd.; and Alan M. Voorhees & Associates, Inc.; and served as Director of the Building Research Board at the National Academies of Sciences, Engineering, and Medicine (NASEM), and as a Senior Program Officer in NASEM’s Cooperative Research Programs of the Transportation Research Board. I received my university education at the Massachusetts Institute of Technology and was a Loeb Fellow at Harvard University’s Graduate School of Design.
