π€ I am Junkai Chen (ιδΏε―), a Ph.D. student at Singapore Management University, advised by π¨βπ« Prof. David Lo. I received my masterβs degree at Zhejiang University, where I was very fortunate π to be advised by Prof. β¨ Xing Hu and Prof. π Xin Xia.
So many exciting and interesting \(β§β½β¦)/ things are happening in the era of AI (especially Large Language Models)!, where code seems to be a promising path from uninterpretable output to grounded actions. I am thrilled to be part of this time, and hope to make meaningful contributions to real world problems, with research at the intersection of Software Engineering and Artificial Intelligence.

[26/9/25] π Check our lastest preprint for evaluating π secure vide coding of code agents! We surprisingly find that, given the historical context of vulnerability introduction, current code agents still fall into human failures, even inducing other security issue!
