Mengdi Huai
I am currently a Ph.D. Student in the Department of Computer Science at the University of Virginia, supervised by Professor Aidong Zhang. My research interests are in the general areas of machine learning and data mining, with an emphasis on developing novel techniques to build trustworthy learning systems that are explainable, robust, private, and fair. I am also interested in designing effective machine learning and data mining algorithms to deal with complex data with both strong empirical performance and theoretical guarantees.
