Dr. Chen researches wireless and systems security, mobile wireless networks, sensor networks, cognitive radios, distributed systems, and bioinformatics. She specializes in using machine learning techniques (e.g., clustering analysis and reinforcement learning) and data mining methods (e.g., dynamic Bayesian learning and ensemble learning) to classify and model the network, system, and healthcare related problems.

She is director of the Data Analysis and Information Security (DAISY) Lab, which focuses on both addressing the problems in information security, system privacy, and data integrity using statistical approaches and machine learning techniques, as well as building test beds to facilitate research in these areas.

Her research has resulted in co-authoring of a book entitled, “Securing Emerging Wireless Systems”, contributions to various journals and conference publications, and sponsorship from the National Science Foundation (NSF) and Department of Defense (DoD) Armament Research, Development and Engineering Center (ARDEC).
