Hi, I am a 3rd year computer science Ph.D student in Virginia Tech. My advisor is Danfeng (Daphne) Yao. I earned my bachelor and master degree in Beijing University of Posts and Telecommunications (BUPT) in China. My research lies in deep learning applications in programming language, software security, and cryptography, including code embedding, learning-based automatic vulnerabilities detection and repair, neural cryptanalysis.

We design and comprehensively compare the neural-network-based methodologies to model Java security API usage. We design the program-analysis-guided embedding strategies to produce the dependence-aware code embedding. We develop a learning based code suggestion engine to suggest the correct API usage based on multiple data dependence paths extracted by program analysis.

We successfully developed a new functionality, finding cryptographic vulnerabilities, in Oracle’s static code analysis tool Parfait. The detection achieves high precision with good scalability for large codebase.
