I am a PhD student of Computer Science Department, Purdue University. My advisor is Suresh Jagannathan. I am working on attack/defense/assurance of deep learning, especially deep reinforcement learning, from the perspective of formal methods. I received my B.Eng. of Software Engineering from University of Electronic Science and Technology of China in 2018.

Although deep neural networks have achieved promising performance in various tasks, they are generally used as black-box functions without any formal guarantee on their properties. For example, without formal analysis, it is unclear whether a neural-network-controlled drone, which is operated in a complex environment, will collide with the ground or not. This line of work provided verifiable safety guarantee for cyber-physical-systems (e.g., robots, UVA) trained with deep reinforcement learning.

Distinguished Paper
Neural network controllers are not robust to adversarial attacks, which exposes them to great threats from malicious attackers. We aim to explore both attack and defense techniques for deep-neural-network controlled systems, thus providing more robust neural network controllers.
