Wei Le  Associate Professor CV

Computer Science, Iowa State University

Research interests: trustworthy software and AI


If you are interested in machine learning for code, machine learning for medicine 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

Congratulations, Ben Steenhoek, Mahbubur Rahman and Richard Jiles, for the accepted ICSE23 paper: An Empirical Study of Deep Learning Models for Vulnerability Detection

Congratulations, Jiongchi Yu, Yuechen Wu, Xiaofei Xie and et al. for the accepted ICSE23 paper: GameRTS: A Regression Testing Framework for Video Games

Research Interests


I am interested in trustworthy software and AI engineering, program and AI model analysis, and the intersection of software engineering and machine learning. I work with Program Analysis & AI Lab at Iowa State University on machine learning for code, machine learning for medicine, software and AI model analysis and debugging, and automating software engineering tasks of bug detection, testing, debugging and repair.
