About

Nirupam Roy is a leading researcher at the intersection of cybersecurity, embedded systems, and robotics, with a focus on privacy vulnerabilities and novel sensing modalities. His most impactful work, "Spying with your robot vacuum cleaner" (83 citations), introduces LidarPhone, a side-channel attack that exploits a robot vacuum’s lidar sensor to eavesdrop on private conversations—revealing how seemingly innocuous smart devices can become surveillance tools. This work, alongside a companion paper (11 citations), has reshaped understanding of acoustic side-channels in ubiquitous computing. Roy also advances low-power robotics: his SPiDR system (31 citations) enables miniature mobile robots to generate spatial maps using a single speaker-microphone pair, while "Enabling Self-defense in Small Drones" (19 citations) pioneers midair collision avoidance for vulnerable drones. His Owlet project explores insect-scale sensing, and his recent work on synthetic aperture sonar (2025) accelerates underwater imaging for autonomous vehicles. With over 140 total citations, Roy’s research bridges security, sensing, and autonomy, earning recognition for exposing hidden privacy risks and creating resilient, miniaturized robotic systems.
