He primarily use and develop geochemical and isotopic techniques to determine age of rocks and their origin. One of his main research fields is evolution of continental collision zones such as the Himalaya or the Carpathians. Geochronology is of my particular interest, especially means of linking isotopic ages with specific geologic events. Prof Anczkiewicz use high resolution Lu-Hf and Sm-Nd garnet geochronology as well as in situ LA ICPMS U-Pb zircon dating to estimate rates of geological processes. 
Recently, he focused on application of isotopes to environmental and archaeological problems.
