Dr. Margareta Pecovska Gjorgjevikj was born in Skopje on 28.2.1963. She completed primary and secondary education with continuous excellent success, as the top student in her generation. She enrolled at the Faculty of Physics in the academic year 1981/82, and graduated in the applied direction, as an engineer of physics at the Institute of Physics at the Faculty of Natural Sciences and Mathematics. In 1987 she was employed as a junior assistant at the Institute. In 1994, she defended her master's thesis in the field of Solar Energy at the Faculty of Physics, entitled: "Influence of the conditions for obtaining Cu­2O thin films by the method of chemical deposition on their structure and some physical properties" and was elected as an assistant at the Faculty. She obtained her doctoral degree in 2002 with the defense of her doctoral dissertation entitled "Electrical characterization of thin films of Ta2O5 for application in microelectronics". She was elected as an assistant professor in 2003, and as an associate professor in 2008. She became a full professor in 2012, and was re-elected in 2017. Since then, she has been a teacher of a number of subjects, such as at the Institute of Physics (Mechanics, Molecular Physics for double major studies in mathematics-physics, Biophysics, Fundamentals of Biophysics, Introduction to Biophysics, Electron Microscopy, Physics of Information Records, Physics of Solar Radiation, Renewable Energy Sources, Modern Microscopic Techniques, Medical Physics, Selected Chapters of Biophysics), at other Institutes at the Faculty (General Physics 1 and 2 for analytical biochemistry, chemistry, Physics for computer scientists, Physics for double major studies in biology-chemistry), as well as at UKIM (three-year studies for physiotherapists, X-ray technicians and speech therapists at the Faculty of Medicine). She prepared appropriate teaching aids for lectures and exercises for all subjects. She is a co-author of a physics textbook for the third year of secondary vocational education. She has been a mentor to several students in the preparation of their diploma theses, as well as a member of the defense committee for several master's and doctoral candidates. She works in the scientific field of experimental physics of organic and inorganic materials for application in solar cell technology, condensed matter physics, electrical characterization of semiconductors and dielectrics, biophysics, etc. She was a member of 12 national, bilateral, international scientific research projects, projects in the field of education and two applied projects for technological development. She was a member of the Editorial Board of the scientific journal Physica Macedonica, a member of the Editorial Board of the Bulletin of Physicists of the Republic of Macedonia, a member of the Scientific Board of several Conferences of the Society of Physicists of the Republic of Macedonia, as well as a member of the Scientific Board of the 12th Conference of the Balkan Physical Union. She is a reviewer of scientific papers in several international journals. She was active in c She was a member of the Self-Evaluation Committee of the Faculty (2019-2023), as well as a member of the Commission for Accreditation of Study Programs for Double-Degree Studies in Mathematics-Physics (2023). For many years, she was actively involved in physics competitions for primary and secondary education, as well as in scientific engineering comp She also held many seminars and lectures for high school teachers and was actively involved in promotion activities for studying physics. Other activities include Secretary of the Society of Physicists oetitions.f the Republic of Macedonia, Secretary of the School "Young Physicists", Head of the Institute's Condensed Matter Department, Head of the Mathematics-Physics double major, reviewer for appointment to a position, reviewer of faculty textbooks.
