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, or analyzing AI models and code, please send your CV to csadmissions@iastate.edu and cc weile@iastate.edu. I am mostly looking for PhD students, but exceptional master and undergraduate students will also be considered.

Recent Work

Research Interests


I am interested in developing trustworthy and responsible software and AI. My reesarch area is at 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, analyzingn and debugging software and AI, and automating software engineering tasks of bug detection, testing, debugging and repair.
