Yucheng Xie, an assistant professor in the Graduate Department of Computer Science and Engineering, aims to develop privacy-preserving smart healthcare solutions through machine learning to enhance daily experiences while addressing security challenges posed by IoT devices. Before joining the Katz School, Dr. Xie was a visiting assistant professor at Purdue University in Indianapolis.
He holds a Ph.D. in electrical and computer engineering from Purdue University and a master鈥檚 degree in computer science from Stevens Institute of Technology. He teaches Advanced Algorithms at Katz School of Science and Health.
Dr. Yucheng Xie, along with a team of computer scientists developed a new way to fight back. Their paper, 鈥淰igilante Defender: A Vaccination-based Defense Against Backdoor Attacks on 3D Point Clouds Using Particle Swarm Optimization,鈥 has been accepted to the prestigious IEEE 34th International Conference on Computer Communications and Networks (ICCCN).
Dr. Yucheng Xie and his team unveiled the DietWatch, a smart, low-effort way to monitor diet using a simple smartwatch at 2025 IEEE/ACM CHASE Conference.
Quotes
鈥淭he integrity of AI isn鈥檛 just a technical issue, it鈥檚 a public trust issue. People need to know that the systems making critical decisions are secure and reliable.鈥
鈥淭echnology shouldn鈥檛 get in the way of living your life,鈥 he said. 鈥淚t should quietly help you live it better.鈥
