My studies are focused on the ecology and taxonomy of freshwater, mostly river diatoms. Examination of diatom samples from various parts of the world inspired my interest on biogeography of microbes. I am also interested in systematics and evolutionary history of monoraphid diatoms that are adapted to life in unstable and high-energy environments. I hope that this site will be helpful for those who work with diatoms, but also for anyone who wants to learn more about these fascinating microorganisms.
