The Faculty of Natural Sciences was established in 1971 and started with three majors - Physics, Chemistry and Biology. In 1991 The Faculty of Natural Sciences added a new major to its profile – Geography. The faculty structures that offered education to students in the above mentioned majors had different names during the years. These were called departments, faculties and institutions. Since 2001 these structures have been transformed into departments in compliance with the requirements stated in the Law on Higher Education. There are 8 departments within the Faculty of Natural Sciences: Theoretical and Applied Physics, Experimental Physics and Methods of Teaching Physics, Organic Chemistry and Technology, General Chemistry, Biology, Agrarian Studies and Plant Protection, Tourism and Geography.      

The educational process at the Faculty of Natural Sciences is performed by highly qualified academic staff comprised by 76 lecturers. There are 37 habilitated lecturers - 6 Professors and 31 Associated Professors. There are also 12 non-habilitated Doctors. The educational process within the Faculty is also performed by leading scholars from the BulgarianAcademy of Sciences and visiting professors from other Bulgarian universities.
