About Me
I am Zihao Wu (吴梓豪), a PhD student at Department of Astronomy, Harvard University, advised by Professor Daniel J. Eisenstein. I am a member of the JWST Advanced Deep Extragalactic Survey (JADES). I received my undergraduate degree from Peking University, where I was advised by Luis C. Ho.
My research focuses on JWST observations of galaxies within the first 500 Myr after the Big Bang. I am interested in the “overluminous” problem, where galaxies at redshift z > 10 appear much more luminous than expected from lower-redshift trends and cosmological simulations. To address this, I use ultra-deep JWST imaging and spectroscopy to study their physical properties. I also study proto-clusters and overdensities, which are expected to host the most massive galaxies at early times. I have contributed to the JADES data reduction pipeline, including sky-flat construction and the removal of scattered-light artifacts.
Outside of research, I enjoy long-distance cycling, hiking, playing guitar, and reading. I have biked over 2,000 km, including a 900 km journey across the Yunnan Plateau, serving as the rear support rider handling mechanical repairs.
