Dr. Donggang Yao is an Associate Professor in the School of Materials Science and Engineering at Georgia Institute of Technology. He teaches and directs research in the broad area of polymer engineering. His ongoing research deals with polymer microfabrication, sustainable composites processing, fiber processing, viscoelastic constitutive modeling, and polymer processing modeling. He was a recipient of the 2003 Career Award from NSF for his research on rapid production of polymer-based microstructures. He was an Assistant Professor at Oakland University before he joined Georgia Tech. More information can be found on his personal website:  http://www.prism.gatech.edu/~dy30
