About Me

I am a final-year PhD candidate at Radboud University in the Netherlands, supervised by Prof. Martha Larson. I will be joining CISPA Helmholtz Center for Information Security in Germany as a postdoc, working with Prof. Michael Backes. My general research goal is to develop trustworthy computer vision systems. Much of my experience has concentrated on adversarial image examples. I also have a background in image forensics and scene recognition.

News

- [09/2021] I have finally submitted my PhD thesis after a long journey of four years.
- [05/2021] I am honored to participate in the Doctoral Consortium of CVPR 2021.
- [08/2020] I am an Outstanding Reviewer of BMVC 2020.
- [07/2020] We are organizing the 3rd edition of Pixel Privacy Task at MediaEval Benchmark 2020. The task will be focused on deceiving the Blind Image Quality Assessment (BIQA) model by adversarially modifying images.
