Le An  Ph.D.


About Me

Researcher in the DEEL project, I am studying how machine learning techniques can be applied for safety-critical systems in terms of robustness, explainability, and data privacy. Before joining this project, I received my Maters's and Ph.D. at Polytechnique Montreal. I empirically studied a wide range of software engineering problems, including software release pipeline, bug triaging and prediction, API recommendation, software licensing, design pattern and anti-patterns. Beyond all these topics, I am also interested in software engineering studies on cloud systems, microservice applications, and high-performance computing applications.
