About Me

I am a PhD candidate at University of Amsterdam (opens new window), supervised by Prof. dr. Theo Gevers (opens new window) and co-supervised by Dr. ret. nat. Martin R. Oswald (opens new window). Also, I regularly discuss research problems with Dr. Fatemeh Karimi Nejadasl (opens new window). Prior to that, I obtained my Master's degree under the supervision of Prof. dr. Zhi Liu (opens new window) at Shanghai University (opens new window).

My research interests include 3D perception, self-supervised learning and open-ended recognition. I also have experience with visual attention modeling, saliency prediction and gaze-based object segmentation during my master.
