Yun Wang

A senior research scientist at California Institute of Technology since 2015, and a professor in the University of Oklahoma's department of physics and astronomy until 2017, she has published over 100 refereed papers, most recently specializing on probing the dark energy in the Universe, with particular attention to the use of supernovae and galaxy redshift surveys as cosmological probes, studies of the cosmic microwave background anisotropy, and the measurement of cosmological parameters.

Yun Wang has developed strategies for optimizing future surveys to probe dark energy, and created a mission concept for the NASA-DOE Joint Dark Energy Mission (JDEM), the Joint Efficient Dark-energy Investigation (JEDI), and served as the principal investigator of JEDI.

The JEDI/JDEM mission concept illustrates the extraordinary efficiency achievable through innovative instrumentation, and the great scientific advantages of combining three independent observational methods (galaxy clustering, weak lensing, and supernovae) to probe dark energy.

Wang has led galaxy clustering science for NASA's Nancy Grace Roman Space Telescope, with launch expected in October 2026.

It will also provide definitive measurements on dark energy, explore dusty regions of the Inner Milky Way, and probe the formation history of the Outer Solar System.
