CLOROX SERVICES COMPANY, Pleasanton, CA 1996 - Present
· 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
· 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.
