I obtained my Transportation System Engineering PhD degree from the University of Texas at Austin in 2002.  I had a great time at the University of Texas at El Paso from 2002 to 2006. Since 2010 I have been an Associate Professor at the Department of Civil Engineering and Engineering Mechanics at the University of Arizona and I founded Metropia, Inc. in 2012. 


I started my academic career focusing in the area of simulation-based dynamic traffic assignment (DTA). I have been a principal developer and consultant to the US FHWA on the Dynamic Traffic Assignment (DTA) program in the 2010s. One of the hallmark tools originating from my research career is DynusT, a simulation-based DTA model that is widely used internationally.


My quest to solving the urban mobility challenges led to the creation of Metropia in 2012. Metropia is an information and incentive-based personal mobility and transportation system management platform aiming to bring Mobility-as-a-Service and Tools (MaaS&T) for future urban mobility management.  Metropia utilizes real-time traffic and incident data and advanced traffic prediction and incentive algorithms to predict future traffic conditions and to use dynamically adjusted incentives pricing as a mechanism to shift demand to less congested times, routes, and various mobility options.
