- PhD Student
I am a PhD student supervised by Professor Robert Mullins and co-supervised by Dr. Yiren Zhao and part of the Computer Architecture Group and the Security Group. I am funded by the Tazaki Cambridge Studentship and a member of Downing College. My research interest is in Machine Learning Security. I am currently (summer 2025) doing a research internship at the Vector Institute under Dr. Nicolas Papernot.
Biography
I finished my MPhil in Advanced Computer Science under supervision of Professor Ross Anderson, Professor Robert Mullins and Dr. Ilia Shumailov in June 2024. During the summer 2024 I was a research intern under Professor Ahmad-Reza Sadeghi. Furthermore, I graduated with a BSc in Natural Sciences (Computer Science, Mathematics) from Durham University under supervision of Dr. Ehsan Toreini and Dr. Gagangeet Aujla in 2023. During this time I also studied abroad for one year from 2021-2022 at the Computer Science and Engineering Department of Seoul National University in South Korea.
