A few words about myself

I am a Postdoctoral Researcher at the Singapore Institute of Technology (SIT), where my current research focuses on quantum communication and quantum key distribution (QKD) networks, with an emphasis on reliable, scalable, and optimization-driven quantum networking.

I received my Ph.D. in Electrical Engineering from the Indian Institute of Technology Palakkad, where my research focused on state estimation and control of networked control systems under uncertain and communication-constrained environments. My doctoral work brought together control theory, wireless communication, estimation, robotics, and cyber-physical systems, with particular emphasis on channel uncertainties, packet losses, distributed estimation, and resilient control. I also developed a real-time hardware-in-the-loop (HIL) platform using software-defined radios and robotic hardware to bridge theoretical developments with experimental validation.

Following my Ph.D., I worked as an IoT Algorithm Developer at a Canada-based technology company, where I contributed to indoor positioning and navigation systems involving Wi-Fi and Bluetooth sensing, localization, signal processing, and learning-based algorithms. This experience strengthened my interest in translating research concepts into practical, deployable intelligent systems.

My broader research interests span artificial intelligence, deep learning, reinforcement learning, networked and autonomous systems, robotics, wireless communication, estimation and control, and quantum communications. I am particularly interested in developing intelligent and resilient algorithms that enable autonomous systems and communication networks to operate reliably under uncertainty, limited information, imperfect channels, and dynamically changing environments.

My research philosophy is centered on connecting theory, learning, and experimentation—developing mathematically grounded methods and validating them on real-world and hardware-based platforms. Going forward, I aim to work at the intersection of AI, autonomous systems, networked control, and emerging communication technologies to develop dependable, adaptive, and scalable intelligent systems for complex real-world applications.
