Vuk Mandic is involved in searches for gravitational waves with LIGO. He co-chairs the LIGO group searching for the stochastic background of gravitational waves, which could be cosmological or astrophysical in origin. He is also involved in the studies of different noise sources that limit the performance of gravitational-wave detectors, and is leading a collaboration studying the possibility of building such a detector underground.

Welcome to the Cosmology Group at the University of Minnesota! We are a diverse but cohesive group of Physics and Astronomy faculty, post-docs and graduate students engaged in research work in Cosmology, Gravitation and related fields. Our research interests span a wide range of topics in the experimental, theoretical and observational Cosmology.
On the experimental side we are involved in all aspects of the Cryogenic Dark Matter Search (CDMS) experiment, in the building of balloon-borne instruments to detect minute signals from the Big Bang as imprinted on the Cosmic Microwave Background, and in the Laser Interferometer Gravitational-wave Observatory (LIGO), a network of multi-kilometer interferometers designed to search for gravitational waves. On the theoretical side we investigate the earliest moments of the Universe, the inflationary epoch whose outcome sets the stage for the later evolution of galaxies and clusters. We map the mass distribution in these structures in order to reveal the properties of dark matter. We also study the origin and evolution of the chemical elements from their production during the Big Bang Nucleosynthesis and in the interiors of stars, to their dispersal by supernova and mixing into the interstellar medium. We carry out observational programs to test theoretical predictions of the chemical evolution models and to uncover new properties of stars and galaxies.
Our weekly Monday lunchtime seminars cover a variety of cosmology and
related topics and are generally accompanied by lively discussions. With
the generous help from the Fine Theoretical Physics Institute we organize
yearly workshops that attract international experts.
