About me

I am currently a fourth-year Ph.D. candidate with the Cybersecurity group at Delft University of Technology under the supervision of Dr. Stjepan Picek. My research interests include the security concern in GNNs, applications of GNNs, and explainable artificial intelligence.

Prior to that, I obtained my master’s degree in Optical Engineering from Beihang University (BUAA) in 2019. My master’s work was about information fusion based on factor graph. Before joining BUAA, I received my bachelor’s degree in Engineering from Shanghai University in 2016. During my bachelor’s study, I worked on machine vision and image processing.
