About

Preetha Thulasiraman is a leading researcher at the intersection of cybersecurity, robotics, and networked unmanned systems. Her work focuses on fortifying the Robot Operating System (ROS) 2 against network threats while ensuring reliable performance in contested and lossy environments—critical for military-grade and autonomous aerial operations. In her highly cited 2020 study (20 citations), she benchmarked ROS 2’s performance under varying Quality of Service (QoS) and cybersecurity settings, revealing trade-offs essential for secure deployment. Her 2019 assessment (17 citations) exposed the inherent security gaps in ROS’s original design and validated ROS 2’s DDS-based architecture as a robust countermeasure for aerial networks. A third influential paper (9 citations) evaluated ROS 2 in lossy, small-node networks, simulating realistic group operations. Collectively, her work has shaped how defense and robotics engineers approach secure middleware for unmanned systems, earning her recognition as a key voice in resilient, real-time robotic communications.
