Welcome to the Turak Research Group!


My research is focused on interfacial engineering in organic optoelectronic devices (OLED, OPVs). We tune the morphology, chemistry, electronic states, and structure at electrode and donor-acceptor interfaces, and study order disorder transitions in semiconducting organic thin films.
