Statement of Research Interests:

My research centers on resilient computing systems that maintain correct, efficient operation under constrained and unstable conditions such as limited energy, intermittent power, variable connectivity, and hardware faults. My work contributes core advances in low-power and battery-free computing, embedded and cyber-physical systems, and runtime and system-level techniques for robustness, adaptivity, and efficiency. These approaches enable computing platforms that can be deployed across a wide range of industries, including environmental sensing, healthcare, infrastructure monitoring, robotics, and defense, where reliability, longevity, and resource efficiency are first-order system design requirements.

Statement of Teaching Interests:

My teaching interests focus on core computer systems, with particular emphasis on computer networking at scale. I am especially interested in designing and teaching large-enrollment networking courses that connect foundational theory—such as protocols, performance, and reliability—to real-world systems, helping students understand how networked computing operates in practice across modern applications and infrastructure.
