About Me

We work in the field of theoretical and computational chemistry with our main focus on multiscale method development and application to technologically and industrially important soft materials e.g. polymers, biopolymers, biomolecules etc.

Computational chemistry emerges as an important tool to predict new properties of matters and complements experimental finding.

We use and develop quantun chemical calculations (DFT, ab-initio HF, Semiemprical methods), classical molecular dyanamics, coarse graining and mesoscale simualtions to solve chemical, biological and material science related problems.
