EXPERIENCE

R&D Technician Polyglass Inc./Mapei (2013.04 - 2013.10)

Developed high tensile self adhesive asphalt-polymer water-proof membranes by using liquid applied

coating method and designed the prototypes for roofing.

Supported product development of R&D department by conducting mechanical, chemical and physical

tests, assisted principle scientist to analyze the test results, write reports, and provide suggestions.

Created standard operation process (SOP) manuals for laboratory equipments, and developed standard

characterization procedures to meet ISO and ASTM standards, improved R&D efficiency 30% by

reducing test time.

Analyzed market trend and proposed a new product line to boost our market share in South America

by reviewing literatures and studying competitor’s products.

Trained colleagues to operate new equipments, and helped internal and external customers on their

characterizations. Supported manufacturing plants and marketing department on raw material selection,

competitive products benchmarking, and products failure prevention.

Managed R&D lab on chemical hygiene, safety inspection, inventory management, and logistic service.

Research Assistant AMPAC, UCF (2010.05 – Present)

Built diblock copolymers PVSZ-b-PS by RAFT polymerization and colloid technique; converted it into

hollow nanospheres, mesoporous material, nanostructured crystal by self-assembling for the applications

in catalyst, bio-medication, and energy storage. Being invited to present this innovative synthesis method

at international conferences (MS&T, ICACC).

Developed polymer monolayer using Langmuir-Blodgett deposition method, and converted it into silicon

carbide thin film with scattering, dendric branch and linear alignment structures.

Formulated poly (aluminasilazane) for SiAlCN thermal and environmental barrier ceramic coating.

Employed FIB to fabricate it into less than 100 nm scale with an extremely smooth surface and super-

high accuracy. Motivated the cooperation of AMPAC with Electricite de France (EDF).

Synthesized carbon nanofibers (20 vol. %) reinforced ceramic nanocomposite with improved toughness

by infiltrating CNF-preform with liquid-phased polymeric precursor.

Designed and synthesized polymer polyborosilazanes with ultra-high yield (90%) and sintered into

SiBCN ceramics with very high thermal stability (2000 Assisted supervisor to compose proposal, and

C).

won a 1.01 million grant from Department of Energy (DOE).

Developed poly(vinylsilazane) for UV and heat cured glass/ceramic coatings, researched and mastered

their structure-property relationships.

Guided a material fabrication team (3 graduates and 1 undergraduate) to design and fabricate

semiconductor devices, it demonstrated excellent performances under harsh environments (increased

operation temperature from 500 º to 1300 º

C C).

Research Assistant Sichuan University, China (2007.09 – 2009.07)

Invented environment friendly organic softener-stearic acid triethanolamine ester quaternary salt through

ionic polymerization.

Synthesized Surfactant Poly(ethylene glycol)acrylate and Poly(ethylene glycol)phosphate as excellent oil

displacement agent, analyzed the surface tension and foam ability.
