Mechanical engineering expertise in thermal and flow analysis, as well as design, including code development and extensive proficiency in using several commercial codes. Experience in securing external research funds and leading engineering teams. PROFESSIONAL EXPERIENCE

General Electric Co. (GE Aviation), Cincinnati, Ohio 1998-2016 Lead Engineer – Thermal

Designed and analyzed high temperature hardware for a range of military and commercial jet en- gines and large industrial gas turbine engines. Created and validated thermal and flow models of turbine blades, vanes shrouds and other components. Interfaced with various customers and tech- nical teams, presented results to chief engineer.

Expanded aircraft maintenance manual limits for CFM56-7 HPT nozzle impacted by dust erosion to improve time-on-wing. Have patent for other improvements.

Developed transient 3D thermal analysis of GE90 LPT nozzle to evaluate throat modifications, complex analysis done in stretch goal schedule to improve product performance at green run.

Developed CFD model of ejector nozzle for F110 after-burner, complex geometry with quick learning curve of software to ensure product safety.

Co-led lean event to reduce cost of building models by 189K annually.

Participated in manufacturing lean event to reduce scrap by 25%.

Turbine Cooling Lead for marine and industrial engines for 6 years.

Lean engineering and quality focal for Airfoils Center of Engineering for 3 years. University of Dayton, Dayton, Ohio 1994-1998

Assistant Professor – Mechanical Engineering

Performed research in CFD including combustion, turbine, and multiphase flows. Taught CFD, Graduate and Undergraduate Fluid Mechanics, Thermodynamics, and Mechanical Engineering Analysis.

Directed the research of one MS and one PhD student.
