RESEARCH EXPERIENCE

Postdoctoral Research Associate, University of Massachusetts, Lowell, MA 2011-present

Advisor: Professor Rudolf Faust

In collaboration with a medical device manufacturer to investigate the structure-property relationship of novel thermoplastic polyurethanes (TPUs) with polyisobutylene as the soft segment (SS). Synthesized a series of TPUs with different compositions and characterized their morphologies and mechanical performance. Revealed that incorporating a polyether diol into the SS has dramatic effects on the structure and mechanical strength of the TPUs.

Graduate Research Assistant, University of Massachusetts, Amherst, MA, 2006 - 2011

Advisor: Professor Thomas P. Russell

Successfully developed a novel approach to tailor the morphology of block copolymers and introduce specific functional groups using alkyne/azide click chemistry. Synthesized a series of novel alkyne-functionalized diblock copolymers. These copolymers were found to undergo morphological transitions when blended with an azide additive and thermally annealed. Such phase transitions were systematically investigated both in the bulk and in thin films.

Successfully used block copolymer thin films to generate nanoscaled structures with controlled geometries on the surface of a serials of semiconductor materials, which were used by a collaborator as template to fabricate novel semiconductor and electronic devices

Undergraduate Research Assistant, Peking University, Beijing, China, 2004 - 2006

Advisor: Professor Er-Qiang Chen

Investigated assembly behavior of amphiphilic diblock copolymer at the air/water interface and revealed the effects of surface pressure on the morphologies of surface micelles.
