Principal Engineer
San Antonio, Texas, United States
• Experience in many areas of engine exhaust aftertreatment research and development and integration of such systems with engine management systems. Project work included the development, modeling, evaluation, and integration of various aftertreatment systems for both gasoline and diesel applications, including particulate filters, Selective Catalytic Reduction (SCR), oxidation catalysts, as well as combined technologies such as SCR on filter.• Served as a project manager for numerous engine and aftertreatment programs. Responsibilities included managing a team of engineers, wrote many proposals and technical reports, prepared and managed program budgets, designed test apparatuses to meet clients’ needs, and communicated with clients on a regular basis.• Derived accelerated aging protocols for gasoline, CNG, and diesel aftertreatment devices that replicate real-world deactivation mechanisms.• Assisted the European Union Commission and California Air Resources Board with developing regulations for accelerated aging and verification procedures for aftermarket replacement diesel aftertreatment devices. The protocols and algorithms developed in my tenure at SwRI are referenced in these regulations.• Modeling efforts included prediction of urea derived deposits in SCR systems. • Commissioned numerous test stands capable of completing various forms of aftertreatment performance and durability studies. Established controls on engines and burner systems to demonstrate accelerated aging of engine aftertreatment systems.• Managed all burner activities that covered aftertreatment durability testing and evaluations on SwRI’s ECTO-Lab burner system. • Managed a joint industry program, the Advanced Combustion, Catalyst and Aftertreatment Technologies (AC2AT) consortium.
