Asen Dotsinski
About me:
I am Asen Dotsinski, a PhD student at INSAIT since August 2026, where I am supervised by Dr. Yuxia Wang.
My research is on the security of open-weight large language models. I am driven by the goal of keeping increasingly capable AI safe as it proliferates, and I currently work on adversarial robustness against jailbreaking. I am also interested in tamper resistance and categorical unlearning, as complementary approaches to defence-in-depth.
