Uros Seljak (born May 13, 1966 in Nova Gorica) is a Slovenian cosmologist, a professor of astronomy and physics at University of California, Berkeley. He is particularly known for his research on cosmic microwave background radiation, galaxy clustering and weak gravitational lensing, and the implications of these observations for the large scale structure of the universe.
After finishing the Nova Gorica Grammar School, Seljak did his undergraduate studies at the University of Ljubljana, Slovenia, graduating in 1989, and received a master's degree from the same institution in 1991. He then went to the Massachusetts Institute of Technology, receiving his Ph.D. in 1995. After postdoctoral studies at the Harvard-Smithsonian Center for Astrophysics, he took faculty positions at Princeton University, the International Centre for Theoretical Physics in Trieste, Italy, and the University of Zurich, before joining the Berkeley faculty in 2008. At Berkeley, he also holds a joint appointment with the Lawrence Berkeley National Laboratory.
In 2001, he won the Helen B. Warner Prize for Astronomy which is awarded annually by the American Astronomical Society to a young astronomer. Together with Matias Zaldarriaga, he developed the CMBFAST code, the first computationally efficient method for computing the anisotropy of the cosmic microwave background radiation for an arbitrary set of cosmological parameters.
Seljak's thesis students include Matias Zaldarriaga, Kevin Huffenberger, Chris Hirata, Rachel Mandelbaum, Nikhil Padmanabhan, Lucas Lombriser, Nico Hamaus, Tobias Baldauf, Zvonimir Vlah and Jonathan Blazek.
