Dr. Jelena Nedjic

Jelena Nedjic is a Principal with Catenion and lives in Berlin.

The cloning of sheep Dolly changed Jelena’s path forever, as this accomplishment of human kind awoke her interest in biology. Thus, she left her country of origin to gain deep insights into modern science that involved living in four different countries on two continents. After completing her Diploma studies she moved to Vienna, where she enrolled in a PhD program at the prestigious Institute of Molecular Pathology, under the supervision of Prof. Dr. Ludger Klein. There she studied the mechanism of T cell development and tolerance induction, which sparked her interest in the immune system. Jelena’s scientific quest led her to Munich, New York City and Biberach an der Riss. Supported by the Damon Ranyon Cancer Research Foundation and the Marie Curie Program of the European Union, she learned about the intricacies of this powerful cell type and its ability to heal various diseases. Prior to joining Catenion she held the position of Research Laboratory Head in the Cancer Immunology and Immuno-modulation department at Boehringer Ingelheim. She authored and co-authored scientific papers that shed light on long-standing mysteries in biology of T cell education in the thymus.

In her spare time she is trying to understand how evolution has shaped the immune system as we know it today. Apart from that, she was involved with non-governmental organizations with the mission of supporting science and technology, and along the way she made significant contributions to establishing the first ever Science Television Program in Serbia.


Jelena studied Molecular Biology and Physiology at the University of Belgrade. Following that she gained a Dr.rer.nat from the University of Vienna, and further specialized as a Postdoctoral Fellow at the New York City School of Medicine and the Institute of Immunology, Ludwig Maximilans University in Munich. She is grateful that she met giants of immunology on her journey from whom she had a valuable opportunity to learn along the way, and she will be forever grateful to her mentors.
