I have over thirty years of technical and business expertise in advanced water technology development and commercialization. My expertise covers areas including industrial water treatment, membrane separation processes, electrochemical processes, energy technologies, and chemical sensor technologies. As part of my prior experience, I have planned and executed programs to develop, scale up manufacturing of, and commercially prove new ceramic membrane products that satisfied market needs. I also identified and developed new value creation opportunities and provided close technical support to business development team efforts in key markets. I have held other relevant responsibilities, including manufacturing development in troubleshooting tasks to support scale-up and cost reduction, as well as managing field service engineers on pilots to support commercial proposals, and execution of commissioning, start-up and troubleshooting. Finally, I have served as PI or PD on about fifty federally funded applied R&D programs, primarily through SBIR.

Contributions to Science
My Master’s thesis research evaluated surface chemistry and colloidal properties of aluminum magnesite spinel. R.J. Higgins, H.K. Bowen, and E.A. Giess, “Preparation and Sintering Behavior of FineGrained MgAl2O4-SiO2 Composites,” pp. 691-98 in Advances in Ceramics, vol. 21: Ceramic Powder Science, American Ceramic Soc., Columbus, OH, 1987.
My Doctoral thesis identified, for the first time, specific surface chemical and pyrolytic chemical mechanisms for carbon contamination retention occurring during manufacturing of multi-layer metallized ceramic microelectronics substrates. R.J. Higgins, W.E. Rhine, M.J., Cima, H.K. Bowen, and W.E. Farneth, “Ceramic Surface Reactions and Carbon Retention during Non-Oxidative Binder Removal: Al2O3/ Poly(methyl methacrylate) at 20°-700°C,” J. Am. Ceram. Soc., 77 , 2243-53 (1994).
During my post-graduate career, my full focus has been on applied research, product and process development as opposed to basic science. However, I have collaborated with academic researchers occasionally in separations and materials science, e.g.: a. Y.S. Lin, W. Ji, Y. Wang, and R.J. Higgins, “Cuprous-Chloride-Modified Nanoporous Alumina Membranes for Ethylene-Ethane Separation,” Ind. Eng. Chem. Res., 38, 2292- 2298 (1999). b. S.J. Lombardo, D. Bianchi, B. Bishop, A. Giannakopoulos, R. Higgins, R. Goldsmith, R. Pober, S. Suresh, “Forming of Ceramics During Firing Without the Application of External Pressure,” J. Am. Ceram. Soc., 82 , 1401-08 (1999).
