In 2003, MIT - DUSP offered the first e-Planning Seminar. 20 years later, e-Planning Science matured. At MIT-DUSP, it originated the UIS PhD area, initiatives like urban computing and a new multi-disciplinary College. In Portugal, it gave birth to a Joint PhD Program by 4 Universities; an e-Planning Consortium, with MIT + other Institutions, also in Brasil. After covid pandemics, Digital Transition is now a world key agenda; e-Planing is best placed to help. It is therefore timely to offer a new e-Planning Seminar at MIT, an opportunity for young faculty and students to benefit reflect on the accumulated experience, the lessons learned, and how that should inform our research agenda in the future.
