Lead for engineering and technology development of Tesla's batteries, motors, drive units, power electronics and our energy products. Accountable for Tesla's charging and energy businesses, and cell and energy manufacturing operations.

Led Tesla's energy products engineering team; led engineering for Tesla's core technology areas: battery cells, motors, drive units, power electronics, HV and battery safety, powertrain performance modeling, system optimization, and controls.

Led engineering and product definition and development for Tesla's stationary energy storage systems, Powerwall and Powerpack.

Led the team focusing on electric vehicle powertrain modeling, analysis, optimization, and requirements definition for batteries, motors, chargers, and inverters for various vehicle platforms and for stationary storage applications. Coordinated and led architecture definition, implementation, and integration of motor control, charge control, vehicle dynamic control, vehicle integration, and battery management systems across the powertrain. Defined high voltage and low voltage system requirements for EV powertrain components. Defined architecture, control algorithms, and vehicle integration for advanced driver's assistance technologies.

Led a small team focusing on powertrain modeling, analysis, optimization, and requirements definition for the battery, motors, charger, and inverter for Model S. Coordinated and led architecture definition, implementation and integration of motor control, charge control, vehicle dynamic control, vehicle integration, and battery management systems across the powertrain. Defined high voltage and low voltage system requirements for all components in the vehicle.

Led requirements definition, design, and implementation of the next generation of battery management and control electronics and firmware, first deployed in Tesla's batteries supplied to SmartEV and Daimler A class vehicles and highly leveraged into Model S and X.

Part of a small group who completely re-architected the control electronics and firmware of the Roadster power electronics module. Led firmware development for motor, traction, and driveline control for the Roadster.

Transportation policy modeling, investigating cost-benefit of transit and roadway improvements vs. various toll strategies in the Washington, DC metropolitan area.
