Wei Le  Associate Professor CV

Computer Science, Iowa State University

Research interests: trustworthy software and AI


If you are interested in finding/fixing vulnerabilities, machine learning for code and/or analyzing deep learning systems, please send your CV to weile@iastate.edu. I am mostly looking for PhD students, but exceptional master and undergraduate students will also be considered.

Recent Work and News

We thank CERT and SEI@CMU for the collaboration and grant on managing security vulnerabilities in the continuous integration

Congratulations Mohammad Wardat for the accepted ICSE21 paper: DeepLocalize: Fault Localization for Deep Neural Networks

Please check out our open source tool: Hydrogen is a program analysis tool that can compare and analyze software versions and evolution. It has been used in our program analysis class

Research Interests


I am interested in software engineering, program analysis, and the intersection of software engineering and machine learning. I work with Program Analysis Lab at Iowa State University on the topics of automating software engineering tasks of bug detection, testing, debugging and repair as well as big code analysis and safe AI.
