Xinyun Chen (陈 昕昀) Email: xinyun.chen at berkeley dot edu   Hi! I am a Ph.D. candidate at UC Berkeley, advised by Prof. Dawn Song. I received my B.S. degree in Computer Science from ACM Honored Class, Shanghai Jiao Tong University. I was a research intern at Google Brain, working with Denny Zhou and Chen Liang; a research intern at Facebook AI Research (FAIR), working with Yuandong Tian; a research intern at UC Berkeley, working with Prof. Dawn Song; and a visiting student at National Institute of Informatics, working with Prof. Helmut Prendinger. My research lies at the intersection of deep learning, programming language, and security. Currently, I mainly focus on neural program synthesis and adversarial machine learning.   Publications [Google Scholar] | Awards | Education | Talks | Services | Misc.

[Call for Papers] I am co-organizing the Workshop on Adversarial Machine Learning in Computer Vision in CVPR 2020. Please submit your paper here!

Miscellaneous

In my spare time, I enjoy listening to all kinds of music. I have played the piano since kindergarten, and received the highest-level certificates of piano and music theory in China. I used to play some other instruments, including recorder and harmonica.
