Research Interests

Research of my group focuses in the area of theoretical and computational chemistry. We develop, implement and apply novel quantum mechanical and classical methods to study complex chemical problems. Methods developed in our group are applied to study:

1. Valence and core-level spectroscopy

2. Photochemistry in gas and condensed phase

3. Noncovalent interactions 

4. Electron transfer processes in electronic materials
