Paweł Świt, a recent graduate from analytical chemistry at Jagiellonian University in Kraków and chemical technology at AGH University of Science and Technology in Kraków. He is currently a PhD student at Faculty of Chemistry at Jagiellonian University. His research focus on development of new calibration method in flow techniques, especially on generalized calibration strategy in chemical analysis. In the previous year, he held a research internship at the Charles University in Prague, during which dealt with the development of two component method for the simultaneously determination of paracetamol and caffeine in pharmaceuticals. His project at DCU involved the development of an ultra-sonication method of sample preparation for polycyclic aromatic hydrocarbons (PAHs) and pesticides in the surface water samples.
