I am a theoretical cosmologist, and work as a professor of Physics at the University of Michigan. Before Michigan I was an NSF postdoctoral fellow at Kavli Institute for Cosmological Physics and the Department of Astronomy and Astrophysics at the University of Chicago, before that a postdoc in the Particle-Astrophysics Group at Case Western Reserve University, before that a graduate student at the University of Chicago, before that an undergraduate at MIT, and still before that a student at Gimnazija "Ognjen Prica" in Sarajevo, Bosnia and Herzegovina (then Yugoslavia).
I work on trying to understand the nature and properties of "dark energy", a mysterious component that makes up about 75% of the energy in the universe and makes it accelerate. This includes using type Ia supernova measurements, large-scale structure surveys, and cosmic microwave background (CMB) anisotropies as tools of precision cosmology. I am also interested in testing the statistical isotropy of the universe (whether, on average, it looks the same in every direction we observe). And I study signatures of the early universe in the present-day astronomical observations, applying various methods to learn about the universe moments after the Big Bang.
