Dr. Yongxin (Jack) Liu is currently an assistant professor of data science at Embry-Riddle Aeronautical University. Dr. Liu joined the Security and Optimization for Networked Globe Laboratory (SONG Lab) in 2017. His research focuses on Explainable AI for aviation and particularly for signal intelligence. He's the creator of zero-bias deep learning, which is applied in explainable AI and anomaly detection. He's also the creator of the Channel Separation Incremental Learning algorithm, which harnesses the catastrophic forgetting issues in deep learning with mathematical assurance and applied in ADS-B signal identification systems. Other than that, his early work in unauthorized drone detection has resulted in two patents and was cited as first reference by the Department of Defense in August 2021.
