- Addressing ongoing process and product performance issues for a chemically altered biopolymer.
- Efforts leading to a substantial reduction in defects for this business critical product.
- Innovating with polysaccharides and enzymatic treatments to give a client access to a multimillion dollar opportunity.
- Directed the technical efforts on a million dollar government contract to develop and scale up a new chemical and biological protective garment for the Department of Homeland Security.
- This program involved working with government agencies and end users to develop and rank product requirements, evaluating available products and technologies to meet the requirements, and then managing a team of six internal technical experts and multiple subcontractors to develop and run pilot-scale trials for an optimal garment material.
- Evaluated membrane materials for advanced dangerous chemical removal applications.
- Integrated nanotube sheets and nanomaterials into textile systems and tested product efficacy for advanced protection.
- Developed antimicrobial coatings to kill viruses, spores, and bacteria that contact a material surface.
- Researched advanced extraction processes to concentrate therapeutic agents from natural sources for consumer use.

The Clorox Company, Pleasanton, CA, Scientist II, 2003 - 2005
- Innovated new products, executed product improvements, and implemented costs savings projects to meet consumer and customer needs for this consumer products industry leader.
- Executed research, led teams, and managed project timelines to drive business growth.
- Moved new products from bench to pilot and ultimately to production scale.
- Led a technical team in developing refrigerator filter products with the potential to grow the business unit over 20%.
- The team addressed complex challenges including part and injection mold development, part assembly, filter development, regulatory compliance, legal and patent infringement evaluation, high volume manufacturing scale-up, and packaging.
- Assumed role of overall project manager (overseeing marketing, sales, and technical teams) in a rapid response product development project required to meet time critical customer needs. This project filled a customer demand for new consumer preferred designs to increase sales and drive Brita promotion campaigns.
- Worked to develop color changing coatings that could be added to a variety of substrates as a performance indicator.
- Derived methods and executed programs (both experimental and finite element modeling) for determining flow patterns in fixed bed particulate filter systems. This independently initiated research pointed to methods that more efficiently use the filtration media so that a substantial cost saving (up to $1 million per year) was achievable with no negative impact on filter performance.
- Determined new capital and material costs to evaluate the financial viability of projects throughout the development process.
- Performed hands-on experimental work with various adsorption and ion exchange media (some agglomerated materials) for the removal of dangerous contaminants from drinking water.
- Experimented with nonwoven filtration media and membranes for particulate removal. This work addressed a major consumer dissatisfier, and was expected to increase sales of Brita's best- selling product by over 10%.
- Drove efforts in determining secondary suppliers and new primary suppliers for a wide range of products. In one case, found a new supplier vastly superior to the original by virtue of a 15% lower part cost and a 20% faster response time.
- Ensured that products and product claims were in compliance with regulatory agency mandates.
- Spearheaded efforts to determine the cause of failure in products.
- Performed safety audits in the corporate technology center.
Novellus Systems, San Jose, CA, Sr. Process Engineer, 2000 - 2002
