o Responsible for complete electric system engineering for electric powertrains for the NA team o Responsible for expanding and growing the NA team to take on major electric production programs o Led most customer interface and development activities for NA business

o Managed a multidisciplinary team of direct reports which include CAE analyst, metallurgist, and test engineers o Responsible for the timely execution of electric beam axle analysis and testing to enable valuable correlation between analysis and physical testing o Managing budgets, timelines, test planning and design validation activities within Allison and 3rd party test facilities o Successfully completed validation of electric motor and inverter system testing and tuning

o Managed the electric beam axle advanced engineering team of traction motor and gear engineers, metallurgy and CAE/FEA engineers o Led and managed traction motor and inverter system development for the electric beam axles through suppliers o Responsible for assessing motor/inverter system selection, conduct trade-offs studies to evaluate performance, cooling, NVH, and motor design o Involved in the design process from initial layout sketches and system packaging to gearing and shift actuation design which resulted in several patent applications

o Led the development of Proterra’s DuoPower – an integrated EV beam axle – from concept to production o Achieved an overall 12 dBA of noise reduction in the eBeam Axle o Achieved about 20% increase in efficiency over Proterra’s standard powertrain which enabled Proterra’s Catalyst E2 bus to set the world record of 1,101.2 miles traveled on a single charge o Worked directly with customers to assess their needs, provide technical solutions to define product specifications o Responsible for planning, organizing and developing detailed resource structure, timing and budget estimates in the execution of design programs o Key team member in establishing AxleTech’s EV division which involved staffing and org structure; this division was then acquired by Allison Transmissions to form Allison e-Axles in April 2019*
