Objective

To obtain a challenging and rewarding position in polymer processing and

materials development.

Summary

( Five-year intensive experience in polymer processing, especially

injection molding and extrusion of PP, PE, PS, PVC, Nylon, PC, PMMA and

nanocomposites.

( Five-year extensive experience in sealant/adhesive formulation to develop

new products and improve existing product lines, and customer technical

support.

( Four-year professional experience in polymerization, materials

development and characterization, polymerization reaction engineering,

process development, optimization, and scale up.

( Highly creative, strong problem-solver, strong communication and

interpersonal skills to work with all levels of personnel, and proven

ability in handling multiple projects.

Experience

Chemist, W. R. Grace, Boston, MA, 2006 - 2009

( Led global water-based beer/beverage sealant development from bench top

formulation to commercialization with FDA compliance. Four products

commercialized with annual sales of $20M+.

( Supervised and planned staff member's research activities, and

communicated with inter-department teams for successful implementation of

various technical projects.

Sr. Engineer, Nanomaterial Innovation Ltd., OH, 2005 - 2006

( Led NSF product and process development of thermoplastics PVC/clay &

carbon NT nanocomposite and patented nanocomposite foams in extrusion. PIs

of NSF funded projects with the budget of half million dollars.

PostDoc, Center for Advanced Polymer and Composite Engineering (CAPCE), OH,

2004 - 2005

( Led product and process development of thermoplastics PS/clay

nanocomposite and nanocomposite foams in extrusion.

( Led the research project of micro-injection molding. Conducted research

on potential mass-production of biomedical devices with microfeatures.

Optimized the molding process to launch products successfully. Visualized

the molding process to solve problems.

Graduate Research Associate, The Ohio State University (OSU), Columbus, OH,

1998 - 2004

( Investigated the surface defects during injection molding and extrusion.

Made a significant contribution to the understanding of the effects of

morphology, crystallinity, rheology, and process parameters on the surface

defects. Successfully launched surface defect free product.

( Successfully developed virgin/post-consumer blended HIPS for injection

molding through solid understanding on structure/processing/property

relationship. Developed a new approach to simulate the molding process.

( Investigated polymer degradation of PVC in injection molding process.

Successfully predicted the degradation by simulation.

( Strong interaction with industry while on academic studies. Worked on

joint projects with Dow, Kodak, PolyOne, and Visteon on various projects.

Research Engineer, Yuzhu Adhesive Co., Ltd., China, 1996 - 1998

( Developed a polyurethane adhesive, scaled up the process, and

commercialized the product for construction applications. Supervised

technicians. Worked on quality control. Interfaced with materials suppliers

and costumers to modify/improve the adhesive

Research Engineer, National Lab of Polymerization Reaction Engineering,

China, 1992 - 1996

( Invented a novel coagulation process for MBS latex by studying the

mechanism of particle formation, morphology control, and coagulation

dynamics. Implemented the coagulation process into product line for higher

quality product at Qilu Petrochemical Corporation, China. Saved 10M

dollars.

( Led the projects of hydrodynamics, mixing, heat transfer in gas-liquid

agitated vessels.

( Worked on fluid mechanics, heat transfer, and scale-up in agitated

vessels with viscous fluid. Designed effective scraped-surface rotators to

ameliorate a butadiene rubber polymerization reactor.
