I am currently a second-year Ph.D. student in the Department of Computer Science at North Carolina State University, advised by Prof. Xipeng Shen. I also collaborate closely with Oak Ridge National Laboratory, under the supervision of Dr. M.A.H. Monil and Dr. Seyong Lee. I received my Bachelor’s degree in Computer Science and Engineering from Huazhong University of Science and Technology in 2023. During my undergraduate studies, I was an exchange student at the University of California, Santa Barbara (2022–2023), supervised by Prof. Zheng Zhang.
