Ziqi Fang is a postdoctoral associate and instructor in the Department of Mathematics at MIT, as well as a member of the Digital Learning Lab at MIT Open Learning. Working closely with faculty in Math and DLL, Ziqi develops course curricula for residential and global modules leveraging the open edX and MITx Online platforms. Prior to joining MIT, Ziqi earned his Ph.D. in mathematics from the University of Pennsylvania, working on topology and geometry — roughly speaking, the “shapes of spaces” — with a particular focus on the infinite-dimensional spaces encompassing certain natural structures on manifolds. More generally, Ziqi has a dual background in mathematics and theoretical physics, and feels a genuine enthusiasm for education in both subjects.
