My Resume

Research Interests:

·        Wettability and fluid flow in porous media: Alteration of rock wettability from liquid-wetting to neutral wetting by chemical treatment with fluoro-polymeric surfactants, improving liquid mobility and reducing water and condensate blocking around a well, resulting in increase of gas production in gas-condensate reservoir.

·        Surface wetting and cleansing: Apply the technological concept of nanoparticle structuring in the wedge film confinement to the surface wetting and cleansing using complex fluids consisting of surfactants/ micelles/ nanoparticles/ macromolecules.

·        Colloidal assembly and ordering: Apply the technology of colloidal particle ordering in confined geometries (liquid film, interface or porous slit) in the development of nano-materials with desired structural properties and in the stabilization of emulsions and foams.

·        Particle interaction and structure: Elucidate the effect of collective interactions on particle structuring in the multi-particle system through a 2D hard-sphere and a 2D charge-sphere system of granular material.

·        Emulsion polymerization: Develop the optimized surfactant formulation for latex synthesis in emulsion polymerization to achieve the desired particle size, concentration and stability. Verify the mixed micelle model and micellar nucleation mechanism.   

·        Oral mucosal drug delivery system: Develop OMDDS product, a novel non-invasive drug delivery system for those drugs which are invalid by the peroral administration due to their extensive first-pass hepato-gastrointestinal metabolism. 

·        Aromatherapy: Develop new applications and formulations of complex essential oils used in the area of pharmaceutics and toiletries, based on the principle of synergy.

·        Specialty chemicals: Technical development of specialty chemicals used in plastic, rubber, coating, paper, pharmaceutic and cosmetic industries.

Education:

Ph.D. in Chemical Engineering, Illinois Institute of Technology (2006)

M.S. in Chemical Engineering, National Taiwan University (1995)

B.S. in Chemical Engineering, National Taiwan University (1993)
 

Research Activities at RERI:

Wettability alteration of porous media from water/oil wetting to neutral wetting (intermediate gas wetting) by chemical treatment of fluoro-polymeric surfactants. An increase in liquid mobility is achieved, preventing the accumulation and blocking of water or condensate in gas-condensate reservoirs, resulting in increased gas well deliverability and gas production. Elucidate the effect of chemical species, concentration, treatment process, rock type, and salinity on wettability alteration.
