Experimental Sciences & Mathematics

Dr. Alexander Voityuk leads the group "Electron transfer in biomolecules" in the Departament de Química & Institut de Química Computacional. He obtained his PhD in Physical Chemistry (Institute of Inorganic Chemistry, Academy of Sciences, USSR ) in 1983. 1985-1992 he was Associate Professor of Physical Chemistry and led the Quantum Chemistry group at the Institute of Bioorganic Chemistry (Novosibirsk, Russia). Before obtaining his ICREA position in 2004, he was a senior research associate at the University of Zurich, Switzerland (1992-1995), Technical University of Munich (1995-2000) and Max-Planck-Institute of Quantum Optics, Garching, Germany (2000-2004). He has published >150  articles with more than 2000 citations in the field of quantum chemistry and computational modeling of charge transfer in biomolecules.

Research interests

Electron transfer (ET) and excitation energy transfer (EET) are very important processes in biochemistry and material science. The main area of my research is the development of theoretical and computational tools to explore ET and EET in biomolecules and organic materials and the use of the elaborated techniques to understand the underlying mechanisms that control charge and exciton migration in the molecular systems. The effects of structural fluctuations on the ET and EET properties of DNA are of special interest.
