梦旅人的科研之家

My name is Jianping Cai, an Assistant Professor in Faculty of Data Science at City University of Macau. I hold a Ph.D. from Fuzhou University, awarded in 2024, where I also earned my Master's degree in 2016. My academic journey has been driven by a relentless pursuit of knowledge and innovation in the realm of data science.

My research explores the forefront of modern data science, with a focus on critical areas such as differential privacy, federated learning, matrix analysis and optimization theory, big data technologies, recommender systems, and the mathematical underpinnings of machine learning. These disciplines form the foundation of my commitment to advancing both theoretical and practical understanding in the field.

With a deep passion for bridging theoretical concepts with real-world applications, I am dedicated to fostering innovation that transcends the boundaries of academia and industry alike. For further insights into my work, I invite you to visit my faculty page: City University of Macau.
