My research activity is primarily devoted to the experimental study of thermal properties of the condensed matter physics at low temperatures. In particular

¨ Heat transport in glasses and impurity crystals
¨ Dynamic of quantum molecular rotor in ordered and disordered lattices
¨ Phonon-rotational coupling and tunnel phenomena in molecular solids
¨ Heat capacity of disordered molecular solids
¨ Cryogenics, calorimetry and automation of measurements

My last publications for 1998-2009 years.
