Xinjian Luo（罗欣剑）

Ph.D. Candidate School of Computing National University of Singapore Advisor: Prof. Xiaokui Xiao

Bio

I am a fifth-year Ph.D. candidate at the School of Computing, National University of Singapore, fortunate to be under the guidance of Prof. Xiaokui Xiao.

In 2019, I received my master's degree in Computer Science from Shanghai Jiao Tong University (SJTU), where I worked with Prof. Xiaofeng Gao on my master's thesis. Additionally, I collaborated with Prof. Xiaochun Yang on distributed metadata management and Prof. Qianni Deng on designing two-stage exams to enhance student performance. Prior to joining SJTU, I earned my bachelor's degree in Software Engineering from Dalian University of Technology in 2016, where I worked with Prof. Bin Liu on computer-assisted surgeries and Prof. Cheng Guo on secret image sharing. These experiences have enabled me to accumulate valuable insights, hone my technical skills, and gain a better understanding of the computer science landscape.
