I'm a security researcher and PhD student in computer science at Purdue University under the direction of Prof. Xiangyu Zhang since Spring 2018. I previously obtained my B.Sc. degree from Sun Yat-sen University (SYSU) in 2017.
My research interest is security forensics. Currently, I'm working to solve dependency explosion problem during attack investigation phase.
