I’m a Ph.D. student in Electrical and Computer Engineering at Purdue University, advised by Prof. Zubin Jacob (2022–present). My research focuses on physics-informed computational imaging under photon-limited regimes. By bridging optical system design, estimation theory, and information-theoretic analysis, my work aims to push imaging performance beyond conventional resolution limits, with a focus on challenging problems in astronomical and semiconductor imaging.

My early training was in mechanical engineering, where I received both my B.S. and M.S. degrees from Institute of Science Tokyo (formerly Tokyo Institute of Technology). I then worked as a research associate at KAIST while fulfilling my military service, under the supervision of Prof. Seung-Woo Kim and Prof. Young-Jin Kim. During this period, I gained extensive hands-on experience in semiconductor manufacturing, EUV generation, and coherent diffraction imaging, forming the foundation of my current research.
