This is Xianhao Jin’s personal website. I was a Ph.D. student at Virgina Tech, under the supervision of Dr. Francisco Servant. I pursued my Ph.D. degree in May 2022 and became a software engineer of backend and infrastructure. My main research interest focuses on mining software repositories and software engineering empirical studies. Check out my CV here.
