Overview of UM-SJTU Joint Institute (as of 2012) and My Role: The Joint Institute was founded inApril 2006 as a partnership committed to building a world-class academic institution based on the USresearch university model. It offers BS, MS, and PhD programs in Mechanical and Electrical/Computer Engineering. The Joint Institute patterns itself after the premier US research universities inits academic environment, research mission, faculty recruiting and expectations, graduate program,curricula, and tenure system. All instruction is in English. The enrollment exceeds 1200 students, andthey are among China’s best. Internationalization is a major initiative at the Joint Institute in terms ofdual degree, BS/MS, and student and faculty exchange programs.

In the 4.5 years between my arrival and departure, the Joint Institute grew from 3 tenure-track facultymembers to 23, 1 teaching faculty to 9, 8 staff members to 29, only freshmen and sophomores (theoriginal entering classes) to three years of graduating classes, and no graduate program to threeentering classes (80 students) of PhD and MS students with the first group of MS students graduated.

One year after my departure for Virginia Tech, the Joint Institute was recognized by the Institution forInternational Education as the most exemplary international partnership and the recipient of the 2014Andrew Heiskell Award for Innovation in International Education.
