Research work on photocatalysis by Prof. Anna Zielinska-Jurek started in 2006 at Gdansk University of Technology (Poland), including 3-month research stay at Hokkaido University, Training School “Environmental Applications of TiO₂ Photocatalysis” at the University of Oulu in Finland granted by COST Program and Training School “NanoBiophotonics” at the Beckmann Institute, Urbana-Champaign in the USA granted by University of Illinois. At present, her research focuses on the synthesis of functional materials and their characterization, application of photocatalysis in environmental technologies, separation of nanoparticles, magnetic materials synthesis and applications, photoreactor design and development, water and air treatment and nanotechnology.
