Mengnan Du

Ph.D. Student
Department of Computer Science & Engineering


I am currently a 3rd year Ph.D. student in Computer Science at the CSE department of Texas A&M University. My advisor is Dr. Xia Hu. Before that, I received the Master degree  from Beihang University (Beijing, China) in 2017 and the Bachelor degree from North China Electric Power University (Beijing, China) in 2014.

My research is on interpretable machine learning, with a particular interest in the areas of DNN interpretability. I am also interested in areas of adversarial detection, fake news detection, fairness in deep learning, and medical diagnosis.
