EXPERIENCE

 

CLOROX SERVICES COMPANY, Pleasanton, CA                                                               1996 - Present

Process Development Engineer                                                                                                       

·        Designed a mixing system for the suspension of borax and retention of suspension in a thickened base, resulting in a patent for an abrasive cleaner containing borates.

·        Performed production tests at manufacturing facilities

·        Used computational fluid dynamics to suggest an inexpensive modification to process equipment in the plant resulting in tighter control over finished product quality.

·        Designed and built a lab system to use laser scanning, with computer aided data collection and analysis, to measure and control the thickness of steel wool wires during production.

·        Designed an analytical method for screening for toxic byproducts which are released as a result of chemical reaction between bleach materials and organic additives.

·        Leader of team that introduced new information technology tools and developed new web sites for internal company use.

·        Participated on team that evaluated company-wide business practices for the development of future business strategies.

 

LAWRENCE BERKELEY NATIONAL LAB, Berkeley, CA                                                    1990 - 1996

Graduate Student Research Assistant                                                                                                       

·        Developed a mathematical description of the diffusion driven evolution of foam in porous media that led to the discovery of interesting, chaotic behavior, and demonstrated the resulting equilibrium configuration of such systems.

·        Designed and built an experimental system to measure the evolution of pressure adjacent to a packed bed filled with foam during the diffusion driven coarsening of the foam.

·        Created numerical simulations to solve highly non-linear Differential-Algebraic Equations.

·        Supervised an undergraduate research assistant.
