Yechi Zhang

Yechi Zhang is a Postdoctoral Scholar Research Associate in Astronomy at Caltech's Division of Physics, Mathematics and Astronomy. His research utilizes advanced observational data from telescopes including JWST to investigate galaxy formation and evolution in the early universe. Zhang specializes in analyzing chemical abundances, galactic outflows, and AGN-galaxy interactions at high redshifts.

Research focuses on interpreting spectroscopic data to understand physical processes in extreme emission-line galaxies and the role of AGN feedback. Recent work examines nitrogen abundance patterns, outflows in z=3-9 galaxies, and the development of survey methodologies for JWST observations. Zhang contributes to major observational programs including GLASS-JWST and BEACON surveys.
