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 DeepMind (2021), working with Yujia Li; a research intern at Google Brain (2019, 2020), working with Denny Zhou, Rishabh Singh, Petros Maniatis, and Charles Sutton; a research intern at Facebook AI Research (2018), working with Yuandong Tian; and a visiting student at National Institute of Informatics (2015), working with Prof. Helmut Prendinger. My research lies at the intersection of deep learning, programming languages, and security. Currently, I mainly focus on neural program synthesis and adversarial machine learning. I received the Facebook Fellowship in 2020 (blog spotlight).   Publications [Google Scholar] | Awards | Education | Talks | Services | Teaching | Misc.

I am on the job market, and I am looking for both academic and industrial job opportunities starting from Summer/Fall 2022. Feel free to connect!

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.
