Ph.D. Graduation Ceremony ("Promovering") for Radosveta Gencheva
We are proud to celebrate the Ph.D. graduation of Radosveta Gencheva. The ceremony took place on 16 June 2025 at the iconic Stockholm City Hall, marking a significant milestone in her academic journey.
Radosveta successfully defended her doctoral thesis titled “Mechanisms of Action of Thioredoxin Reductase Inhibitors in The Context of Cancer” on 6 December 2024 at Karolinska Institutet. Her research has contributed important insights into the molecular mechanisms of cancer therapy, advancing our understanding of redox biology and its therapeutic potential.
We warmly congratulate Dr. Gencheva on her achievement and wish her continued success in her scientific career!
