Yunjuan Wang / 汪云娟

I'm a theoretical Machine Learning Ph.D. at Department of Computer Science, Johns Hopkins University. I am fortunate to be advised by Raman Arora.

My research interest focuses on Robust Adversarial Learning, Deep Learning Theory. I'm passionate about understanding the fundamental question of machine learning and deep learning, as well as using ML algorithms and data-driven techniques to solve real-world problems.
