Daniel Baumann is a leading cosmologist and the current Director of LeCosPA.


After a PhD at Princeton University, Baumann was a postdoctoral researcher at Harvard University and the Institute for Advanced Study (Princeton). He was a faculty member at Cambridge University and the University of Amsterdam, before joining National Taiwan University. Since January 2024, Baumann is the Director of LeCosPA and the Chee-Chun Leung Professor of Cosmology.

Baumann's research spans a wide range of topics from the physics of inflation to observations of the cosmic microwave background and the large-scale structure of the Universe. He was the PI of an ERC Starting Grant and a NWO VIDI Grant, and is currently a co-PI of the ERC Synergy Grant UNIVERSE+. In 2023, Baumann won a Humboldt Research Award and was awarded a prestigious Yushan Professorship from the Ministry of Education in Taiwan.
