Hi, I am Rui Li (pronounced as "Ray Lee")! I received my Ph.D. from the Massachusetts Institute of Technology (MIT) in 2015, supervised by Professor Edward Adelson at the Computer Science and Artificial Intelligence Laboratory (CSAIL). My passion and interests are in the areas of computer vision, machine learning and robotics, along with many other enabling technologies that may positively impact people's lives. That was also why I co-founded Robby Technologies, building self-driving robots for last-mile delivery, with the mission to significantly reduce the cost of delivery and make it affordable for everyone.

Besides academic work, I have been an active entrepreneur and student leader. In March 2011, I initiated and founded the MIT-China Innovation and Entrepreneurship Forum (MIT-CHIEF) and served as a co-president for two years. MIT-CHIEF has been making a positive impact in the East Coast as well as China, and was recognized as “an important milestone for MIT's engagement with China”. I was also a co-president for MIT Chinese Students and Scholars Association (CSSA), one of the largest international student groups at MIT. I was a recipient of the Joan and Irwin Jacobs Presidential Fellowship (2009) and the first-prize winner for MIT “Pi” Recitation Contest in 2011 (3.141592653589793...).


During my PhD at MIT, I developed a compact and compliant robotic tactile sensor, called fingertip GelSight sensor, that converts touch information to “visual” information using a tiny camera, where computer vision and machine learning techniques can be employed. The fingertip sensor has high resolution, on the order of tens of microns, high compliance and high sensitivity exceeding that of human fingertips. We demonstrated its unparalleled capabilities for fine manipulation, normal and shear force estimation, slip detection, as well as material recognition, and showed its great potential as a new-generation robotic fingertip. My research work was reported in the media including MIT News, The Washington Post, TechCrunch, Engadget, and Gizmodo. (See "News" below.)
