About
SPRAI Lab focuses on the research of Trustworthy AI Systems
SPRAI Lab is led by Dr. Ning Wang, an assistant professor in the Bellini College of Artificial Intelligence, Cybersecurity, and Computing at the University of South Florida (USF). Our mission is to enhance the security and privacy of AI systems, applying advanced machine learning and deep learning methods to solve pressing problems in cybersecurity.
Dr. Wang's research interests include federated learning, network intrusion detection, adversarial machine learning, differential privacy, and the application of large language models (LLMs) in cybersecurity. Under her guidance, the lab explores innovative approaches to trustworthy and robust AI.
The SPRAI Lab welcomes students and collaborators passionate about advancing these fields and making AI systems safer and more reliable for everyone.
Openings
Multiple PhD Openings (with assistantship)
I am looking for self-motivated students with research interests in any area of cybersecurity or the intersection of AI and security. If this opportunity interests you, reach out with your resume and any supplementary material that helps convey your academic background and research expertise.
