Chihway Chang

Chihway Chang is an Associate Professor at the Department of Astronomy and Astrophysics (A&A) at University of Chicago, and a senior member of the Kavli Institute of Cosmological Physics (KICP). She co-leads the Survey Science Group at KICP.

Chihway an observational cosmologist and a survey scientist. Herscience interest is to use large optical survey data to study the evolution of the recent Universe through a technique called weak gravitational lensing. She is particularly interested in extracting information from small scales and high-order statistics. Chihway is also interested in combining the information from weak gravitational lensing with other measurements such as large-scale structure and the cosmic microwave background, to learn about cosmology as well as galaxy evolution and new physics. Currently, she is involved in the Dark Energy Survey, the Vera C. Rubin Observatory’s Legacy Survey of Space and Time, and the Nancy Grace Roman Space Telescope.

She received my undergrad degree at the the Physics Department at National Taiwan University  and finished her PhD in Physics at Stanford in 2013. Chihway’s thesis was on Systematic Effects in Weak Lensing Measurements for Future Optical Surveys under Prof. Steve Kahn and Prof. Rafe Schindler. After her PhD, she served as a postdoctoral researcher at the Institute of Astronomy at ETH Zurich 2013-2016, in the Cosmology group lead by Prof. Alexandre Refregier. And in 2016-2018 she was a KICP fellow.
