Gubenšek"s research focused on neurotoxic phospholipases. In later years, he studied the molecular evolution of snake venom toxins. He co-discovered a novel mobile element of deoxyribonucleic acid and demonstrated horizontal gene transfer of this element between snakes and ruminants in evolutionary history which attracted significant attention of the scientific community.
Apart from his scientific work, Gubenšek chaired the biochemistry department at the Faculty of Chemistry and Chemical Technology (University of Ljubljana), organized several scientific conferences and served in the editorial boards of the journals Acta Chimica Slovenica and Toxicon.
