Hello you! I am Junkai Chen (陈 俊凯), working as a Research Engineer in the Software Analytics Research Group of Singapore Management University, advised by Prof. David Lo. I am also a master’s student at School of Software Technology, Zhejiang University. I feel very lucky to have Prof. Xing Hu as my supervisor, which makes this journey incredibly rewarding and meaningful to me. I am also grateful for the generous support and guidance from Dr. Xin Xia.

In the era of AI, every detail in software engineering is being revisited and reshaped by novel technologies like large language models. In response, my research aims to build more effective, efficient, and reliable AI systems for software engineering, ultimately moving towards fully automated software engineering and creating a world defined by ubiquitous software.
