Tematyka badawcza:

Modelowe studia teoretyczne w dziedzinie katalizy heterogenicznej, homogenicznej i enzymatycznej koncentrujące się na badaniu czynników elektronowych (wpływ nośnika oraz domieszek, efekt liganda) i sterycznych (wzajemne ustawienie reagentów) determinujących selektywność i kierunek reakcji w katalizie. Ich strategicznym celem jest określenie korelacji pomiędzy strukturą centrum aktywnego (liczba i rodzaj sąsiadów, sposób łączenia poliedrów metal-tlen) a jego właściwościami katalitycznymi.

Metodyka:

Metody chemii kwantowej oparte na Teorii Funkcjonałów Gęstości (DFT)
