Leading ACEEE's research, policy, and technical assistance in the buildings sector. Currently overseeing a team of 10 working to achieve ACEEE's Call to Action goals of retrofitting 1/4 of US buildings and ensuring 1/4 of new construction is net-zero-energy and carbon-neutral, including low-income households, by 2030.

Currently leading modeling of the impacts of efficiency policies around the world with the Mepsy Appliance & Equipment Climate Impact Calculator while also supporting new and revised appliance standards in Indonesia and other countries. On Mepsy, managed four staff and two contractors in testing software platforms, writing R code, and developing a web-based user interface.

On Mepsy, managed four staff and two contractors in testing software platforms, writing R code, and developing a web-based user interface. Collected and analyzed data on markets and efficiency for 7 products (air conditioners, refrigerators, space heating, lighting, fans, televisions, and industrial motors) across multiple countries, resulting in a global model of their energy use and CO2 emissions and impacts of potential efficiency policies. Currently extending the model by adding future projections, further appliances and equipment, and different policy options (refrigerants and compliance).In Indonesia, led two staff and five contractors to conduct a first-of-its-kind 5,000+ household residential end-use survey and market and technology assessments that provided key data resulting in efficiency policies for refrigerators, fans, and rice cookers in Indonesia, reducing CO2 by 11 Mt through 2030. Separately, led one staff and four contractors in scoping global water efficiency opportunities that reduce water waste and CO2 emissions, followed by in-depth assessments in Brazil, India, and South Africa. The latter study led to an ongoing review of taps and showerheads standards with the South African National Energy Development Institute (SANEDI). Show less

Led a team of consultants developing electronics efficiency specifications for the U.S. Environmental Protection Agency (EPA) ENERGY STAR program, analyzing the impacts of efficiency standards in Canada, evaluating local sustainability policies in Philadelphia and Arlington County, and implementing a next-generation mid-stream utility incentive program. The ENERGY STAR specifications he helped develop are expected to save the CO2 equivalent to over 3.7 million cars. Conducted research and… Show more Led a team of consultants developing electronics efficiency specifications for the U.S. Environmental Protection Agency (EPA) ENERGY STAR program, analyzing the impacts of efficiency standards in Canada, evaluating local sustainability policies in Philadelphia and Arlington County, and implementing a next-generation mid-stream utility incentive program.

Advised the Department of Energy on the development of energy-efficiency standards for consumer products.

Developed a system of low-cost, micropower active RFID sensor tags for use in supply-chain management and security applications. Field-tested specially-designed sensors, interface circuits, and control algorithms aboard a container ship and aircraft.

Eased customer adoption of a new series of automotive/industrial microcontrollers by developing PCB-level design guidelines for electromagnetic compatibility (EMC). Evaluated EMC strategies through radiation measurements and simulation.

Invented a method of generating 3D sound from close-together cell phone speakers using a phase-delay circuit (later integrated into MAX9775 class-D amplifier). Tested electrical properties of audio transducers and measured emissions from spread-spectrum class-D amplifiers.
