First German-Serbian Knowledge Exchange at ISAS In June, ISAS welcomed Dr Jasmina Živanović and her colleague Dr Marko Miler from the Serbian Institute for Biological Research »Sinisa Stankovic« as guests. Biologist Živanović took part in the »Serbian Science and Diaspora Collaboration Program«. The aim of the EU-funded project is to promote collaboration between Serbian scientists in their homeland and those living abroad. At ISAS, Živanović collaborated with Dr habil. Miloš Filipović, who has been leading the Sulfaging research group since 2020. They wanted to integrate his research findings on persulfidation into her project. Živanović’s and Miler’s goal for their stay in Dortmund was to integrate Filipović’s results from his research on persulfidation (p. 20) into their project.
