I am an assistant professor in the Department of Systems and Information Engineering at the University of Virginia.

My research interests lie in data analytics for smart & connected systems, where multiple entities/units (e.g., vehicles, wearable devices, etc.) collect data and are connected through Internet of Things (IoT) technologies. My research aims at the design and application of data-driven methods that transform a connected system into an intelligent system. To achieve this goal, I explore collaborative data analytics based on methods like federated learning, multi-task learning, and Bayesian probabilistic modeling, allowing entities/units to collaborate to establish enhanced smart analytics based on their connectivity. I am dedicated to addressing crucial challenges in collaborative data analytics to enable harnessing heterogeneous, real-time, and dynamic data for smart & connected systems. The methods developed have contributed to diverse smart & connected system applications, including smart manufacturing and digital health.

• Methodologies: Federated analytics, Meta-learning, Multi-task learning, and Bayesian probabilistic modeling
• Applications: IoT-enabled systems in healthcare and manufacturing domains
