Research interests

I develop the theory which should describe our universe evolution. My main purpose is to formulate the realistic alternative to Einstein gravity in order to resolve the fundamental puzzle of modern cosmology: why and how the universe accelerates? In fact, I proposed the first modified gravity which may describe the unification of the early-time inflation and late-time acceleration, i.e.consistent universe history. We also proposed a bouncing universe in modified gravity as scenario that is alternative to the inflation. The alternative gravity we develop should describe the whole sequence of the universe eras: inflation, radiation-matter dominance and dark energy era. We also continue the search for exotic intermediate eras like pre-inflationary or exotic reheating era. The study of current universe  clarifies its future: if it will expand eternally or if its evolution will be finished in the future singularity.
