Gábor started out by writing about photography. Later, Gábor Kopek recommended that he start teaching courses at the foundation fotografus.hu, which was established by Miklós Gulyás. He joined MOME in the autumn of 2005, teaching courses to photography major students and then to first-year Media Institute students. Since 2019, he has focused primarily on theoretical-historical and art theory issues related to photography.
As a full-time instructor at the Budapest Metropolitan University (METU, formerly the Budapest College of Communication and Business), he delivers courses at the Media Art Institute. He also holds courses and occasional lectures as a guest instructor, temporary instructor and lecturer at the Moholy-Nagy University of Art and Design, the Art Theory and Media Research Institute of the ELTE Faculty of Humanities, the Art History Institute of the ELTE Faculty of Humanities, the Sociology and Communications Department of the Budapest University of Technology, and the Intermedia Department of the University of Fine Arts.
These courses and lectures deal with the history of photography, questions of photography theory, the photograph as a medium in contemporary art, the relationship between photography and architecture and key questions in photography pertaining to social and cultural issues.
He has also served as a lecturer at the MÚOSZ György Bálint Academy of Journalism, teaching photography skills and planning.
He has been invited to give lectures at the Robert Capa Contemporary Photography Centre, the Hungarian House of Photography (Mai Mano House), the Dunaújváros Photo Biennale and the Ludwig Museum of Contemporary Art, focusing on image theory, contemporary photography, the relationship between the press and photography, and the relationship between advertising, fashion and photography between the two world wars.
Gábor regularly publishes critiques, essays and exhibition reviews in the periodicals Fotóművészet and Balkon, and his writings have also appeared in Disegno and the magazines Új Művészet, Műértő, Oktogon and Atrium.
