5G/ORAN Resiliency
O-RAN resiliency is the ability of an Open Radio Access Network to maintain reliable and predictable service even when parts of the system face failures, overloads, misconfigurations, or other disruptions. It is achieved through a combination of architectural design, redundancy strategies, automation, and intelligent control, rather than a single mechanism. As 5G networks evolve toward 6G, meeting stringent Service Level Agreements (SLAs) becomes increasingly challenging, making fault-tolerant networks more critical than ever. O-RAN’s softwarized architecture enables self-healing capabilities, and the integration of AI and machine learning within Near-Real-Time and Non-Real-Time RAN Intelligent Controllers allows networks to proactively detect issues, optimize performance, and recover from faults with minimal human intervention.

Agentic Systems for O-RAN
An agentic system is a technological framework often powered by artificial intelligence in which an "agent" (such as an AI model or software entity) operates autonomously to pursue complex, multi-step goals on a user's behalf. Unlike standard chatbots that merely generate text, agentic systems can perceive their environment, reason through tasks, make decisions, and execute actions by using external tools and APIs to achieve a specific objective .
LLMs for Networking
A Large Language Model (LLM) is a type of artificial intelligence trained on massive amounts of text data to understand, generate, and manipulate human language. By analyzing patterns, context, and relationships between words, LLMs can perform a wide range of task such as answering questions, writing content, summarizing text, translating languages, and even generating code based on a given prompt or instruction.
Network Security
Network Security remains a fundamental challenge across both traditional and next-generation communication networks. It encompasses an adversary's ability to seize control of, intercept, or disrupt critical network services, either by exploiting architectural design vulnerabilities or by leveraging implementation gaps in deployed systems. Such adversaries range from individual threat actors to sophisticated, state-sponsored organizations that intend to compromise system integrity, availability, or confidentiality.
Networks for XR
Our research focuses on next-generation XR-enabled teleoperation systems that integrate robotics, communication networks, digital twins, and edge computing to enable immersive, ultra-low-latency remote interaction. We investigate the networking challenges associated with meeting the stringent requirements of XR-based teleoperation and explore cross-layer architectures to jointly optimize control stability, network performance, digital twin synchronization, and Quality-of-Interaction (QoI). Our goal is to design scalable and reliable real-time remote manipulation and telepresence systems that deliver enhanced user experience.
