Started in 1994 and being inspired by the realisations of the Romanian bryologist Simeon Ștefan Radian, my bryological studies were focused especially on hornworts and liverworts, under the guidance of professors Ioan Cristurean, Simona Mărgăritescu and Gheorghe Dihoru, and continued with the doctoral thesis "Taxonomical and ecological research on the liverworts (Marchantiophyta) from Romania", supervised by Mircea Oltean and Marin Falcă, resulting in a large volume of field data regarding the distribution of these species in Romania, included in the present Atlas.
