Bio
Johannes Lange is an astrophysicist interested in galaxies, cosmology, and machine learning. His work focuses on analyzing large astronomical data sets to extract fundamental insights into our Universe: What are the properties of dark energy and dark matter? Does general relativity hold on cosmological scales? What is the relationship between galaxies and dark matter halos? He's a member of the Dark Energy Spectroscopic Instrument (DESI) collaboration and also works with data from other large-scale galaxy surveys like the Dark Energy Survey, the Hyper Suprime-Cam survey, and the Kilo-Degree Survey.

Before coming to American 青瓜视频 in 2024, he completed his bachelor鈥檚 degree at the Free 青瓜视频 of Berlin and a master鈥檚 degree from the 青瓜视频 of Heidelberg. He completed his Ph.D. under the supervision of Frank van den Bosch at Yale 青瓜视频. Finally, during his postdoctoral career, he was a Cosmology Fellow appointed jointly by the 青瓜视频 of California, Santa Cruz and Stanford 青瓜视频 before being a Leinweber Fellow at the Leinweber Institute for Theoretical Physics at the 青瓜视频 of Michigan.
