About

Mechanical Engineer holding Bachelor of Science degree Professional Experience: Four-and-a-half years of engine calibration experience at a global automaker. Determine appropriate algorithms and their tuning for gasoline and hybrid engines. Specific areas of focus are misfire detection, cold start combustion performance, and hybrid engine auto start-stop. Work with software & controls engineers to integrate diagnostic and control algorithms by tuning them to meet different requirements (both regulatory and drive quality driven) and to function on different vehicle applications. Experience with combustion and mechanical models as well as statistical methods for development and validation of calibrations. Two-and-a-half years of engine calibration verification experience at a global automaker. Development and execution of in vehicle tests for engine controls and diagnostics. Work with calibration engineers, software integration engineers, and hardware engineers on resolution of issues related to engine and emission controls. Track statistical performance of diagnostics to ensure robustness. Two years of design experience of powertrain components at a global automaker. Work with release engineers, analysis engineers, and internal/external suppliers to design production intent engine components. Ensure design adherence to global best practices and provide support for manufacturing/field related issue resolution. Lead design process improvement initiative. College/Internship Experience: Three months as an Engineering Intern at a commercial toolmaker. Conducted process cycle timing and created a suggested workflow spreadsheet for engineering team. Participated in 5S events and created standard operating procedure manuals for grinding and roll forming operations. Three months of manufacturing floor work experience at a die casting and die making plant completed as a summer internship. Four years of research technician experience while enrolled at the University of New Hampshire. Designed and machined spaceflight components for NASA Sounding Rocket Program and conducted thermal management testing for rocket based electronics.
