After receiving her doctorate, Wang did postdoctoral research at
Bell Labs before returning to MIT as a faculty member in 2007. Wang is particularly known for her research on solar-powered devices to extract drinkable water from the atmosphere.
Scientific American and the
World Economic Forum named her technology that produces water from air in an arid climate as one of the "Top 10 Emerging Technologies of 2017". Her water extraction device, which she designed in collaboration with
Omar M. Yaghi, has been compared to the moisture on the desert planet
Tatooine in
Star Wars. However, rather than using refrigeration to condense water vapor, it uses a
metal–organic framework to trap water vapor in the night and then uses the heat from solar energy to release the water from the framework during the day. Her research group has also developed a solar powered desalination system in producing clean water.
Biden administration Wang was nominated by President
Joe Biden in March 2022 as director of the
Advanced Research Projects Agency-Energy of the U.S. Department of Energy. She was confirmed by the
United States Senate on December 22, 2022.
Vice President for Energy and Climate at MIT Wang was appointed as the Vice President for Energy and Climate at MIT in January 2025 by MIT President
Sally Kornbluth. She began in the role on April 1, 2025. ==Awards and honors==
