Cosmology is on a verge of a big discovery. We know that dark energy and dark matter exist but do not know their true nature. No matter what it turns out to be it will revolutionize our understanding of nature at the fundamental level. A number of high profile ground and space based experiments are scheduled to start within next few years with the aim of studying dark energy and dark matter with a high precision. In my talk I will overview research activities of KSU ''cosmic frontier'' group. Our group is involved in three big experiments: DESI, WFIRST, and Euclid. We work on cleaning data from observational systematic effects, coming up with improved statistical methods of extracting useful information from observations, and linking theory to measurements.
