When I was a schoolgirl my parents and I would go hiking all over Russia. Traipsing through the middle of the untamed nature I realized that the most intriguing and complicated objects in our world are living creatures. Now, having studied for four and a half years at Moscow Institute of Physics and Technology and having broad research experience, I am sure that improvement of our understanding of living world is essential for successful existence of our civilization and is the most important thing one can accomplish during his or her life.
