Prior to his current role at the DOE, Minh spent his career in the semiconductor and solar industry developing technologies and scaling new technologies to high volume manufacturing. 

Minh earned his B.S. and M.S. degrees from MIT, where he held fellowships with DOE, the Department of Defense, and the Bose Foundation.


Dr. Becca Jones-Albertus, Photovoltaics Program Manager

Dr. Becca Jones-Albertus manages SunShot's photovoltaics program, which supports research and development to lower the cost of PV electricity through improvements in module efficiency and reliability, and reductions in manufacturing cost.

Dr. Jones-Albertus has spent her career advancing solar cell materials and devices, from research and development to manufacturing. Previously, Dr. Jones-Albertus was the characterization and design manager at Solar Junction, where she led work contributing to the development of the company's breakthrough dilute nitride solar cells, their two-time world record triple junction solar cells, and then the successful transfer of that technology to a high-volume manufacturing toolset. She has 35 technical publications and 8 patents.

Dr. Jones-Albertus graduated magna cum laude from Princeton University with a B.S. in electrical engineering, and also holds a M.S. and Ph.D. in materials science and engineering from the University of California, Berkeley.

Joe Stekli, Concentrating Solar Power Program Manager

Joe Stekli is the program manager for the concentrating solar power (CSP) subprogram within the SunShot Initiative.  Joe has worked for the federal government since 2009. Until 2013, Joe was a technology manager for the CSP subprogram.  From 2013-2014, Joe was a President’s Management Council fellow, working at the White House Office of Management and Budget as an examiner in the treasury branch before returning to DOE and joining Advanced Research Projects Agency – Energy (ARPA-E) as a technology-to-market advisor. 

Before joining the federal government, Joe spent five years working as an engineering manager and process engineer in the semiconductor industry with Micron Technologies and Sumco. 

Joe holds a B.S. in chemical engineering and an M.B.A., both from Ohio State University.

Dr. Elaine Ulrich, Balance of Systems/Soft Costs Program Manager

Dr. Elaine Ulrich is a program manager at the Department of Energy where she leads the SunShot balance of systems/soft costs team.  Her team which works to reduce the non-hardware (soft costs) of solar, lower barriers to solar adoption, and foster market growth through  support for state and local development and technical assistance programs; information & data assets; finance & business model development; workforce & training programs; and policy & regulatory analysis. 

A former American Physical Society/American Association for the Advancement of Science policy fellow, Dr. Ulrich has spent the past few years working on renewable energy. She previously held positions in the office of former U.S. Senator Ken Salazar, U.S. House of Representatives Committee on Science and Technology, the Energy Department’s Office of Strategic Planning and Analysis, and in the office of U.S. Representative Gabrielle Giffords, where she worked to build a comprehensive solar energy portfolio.

Dr. Ulrich holds a B.A. in physics from Wellesley College and a Ph.D. in optical science from the University of Arizona.

Dr. Guohui Yuan, Systems Integration Program Manager

Dr. Guohui Yuan is the program manager for the systems integration (SI) subprogram within the SunShot Initiative. His team supports research, development, and demonstration of technologies and solutions to enable the widespread deployment of solar energy on the nation’s electricity grid.

Dr. Yuan has been supporting the SunShot Initiative as a technical advisor since 2011. Previously, he held several key positions at industry-leading clean technology startups, including CURRENT Group, GridPoint, and WaveCrest Labs. Early in his career, he worked at COMSAT Labs as a systems scientist. He is a recognized thought leader and has many technical publications. He holds nine patents.

Dr. Yuan holds a B.S. degree from Tsinghua University, Beijing, China and a Ph.D. from the University of Maryland, College Park, both in physics.
