Tetiana Obikhod works at the High energy physics department, Kiev Institute for Nuclear Research. Tetiana does research in Computing in Mathematics, High energy physics theory, Cosmology. Using Monte Carlo Computing she studies the properties of new particles predicted by physics beyond the Standard Model: Kaluza-Klein particles, micro black holes, superparticles and Higgs bosons. In the framework of algebraic and toric geometry, the theory of derived category she investigates the properties of space of extra dimensions - Calabi-Yau manifolds. These fundamental researches are of importance for the decision of the problems of Standard Model physics.
