“Collaborative & Secure Intelligence in NextG Edge”
- At the University of Florida, the CoSINE Lab (Collaborative and Secure Intelligence in NextG Edge) pioneers research at the intersection of wireless networking, edge computing, and collaborative intelligence. Our mission is to design resilient, efficient, and secure AI-driven systems that operate reliably under real-world constraints such as limited bandwidth, dynamic connectivity, and adversarial threats. We focus on advancing next-generation wireless and edge-cloud collaboration through innovations in federated learning, distributed optimization, secure adaptation, and intelligent resource management. By blending theoretical advances with experimental validation, CoSINE Lab develops scalable and trustworthy edge intelligence that supports applications in autonomous systems, healthcare, smart infrastructure, industrial automation, and beyond.
