About Me
About Me
I am a sixth-year PhD candidate in the Wireless Communication and Sensornets Laboratory (WCSL) at UC Santa Barbara, advised by Professor Upamanyu Madhow. My expertise lies in signal processing for wireless communications and radar systems, with research spanning mmWave and Tera-Hertz communication systems, Line-of-Sight (LoS) MIMO, and distributed MIMO radar networks.
My doctoral work focuses on designing robust and efficient short-range and long-range LoS MIMO communication systems, with particular attention to system-level challenges such as transceiver panel misalignment and link-range mismatch. More recently, I have expanded my focus into integrated communication and sensing, developing self-calibrating distributed MIMO radar networks for real-time detection and tracking of moving targets.
Alongside my academic research, I have gained industry experience that deepened my understanding of practical system constraints and collaborative development. This perspective enables me to bridge advanced signal processing with real-world implementation and contribute effectively in applied environments.
I am actively pursuing full-time opportunities in industry where I can apply my expertise in signal processing for communications and sensing to address system-level challenges. While I am eager to contribute in areas aligned with my training, I am equally excited to explore opportunities that push me to grow and learn in new technical domains.
