I received my B.S. degree in 2016 from Hanyang University and my M.S. and Ph.D. degrees in 2018 and 2022, respectively, from MIRLAB at KAIST. I then conducted postdoctoral research at KU Lab at Johns Hopkins University. I am currently working in the Department of Radiology at the University of Pennsylvania.

My research has been guided by a fundamental question: How can we visualize the internal structure of objects more reliably and quantitatively? I believe that imaging systems should do more than produce visually appealing images; they should provide reliable, safe, and quantitatively accurate information that people can trust. From this perspective, I have been particularly interested in computed tomography (CT), whose physical principles and measurement models provide a strong foundation for quantitative imaging.

My research focuses on X-ray imaging and CT technologies. During my Ph.D., I developed a strong interest in spectral CT and proposed several new approaches for dual-energy CT reconstruction and material decomposition. One of these research outcomes was later adopted by a startup company and applied in practice (News Outlet 1, News Outlet 2). Currently, my research centers on photon-counting CT, a next-generation CT technology with energy-resolving capabilities, with particular interests in detector modeling, spectral imaging, and quantitative imaging.

My research philosophy is:

Looking ahead, I aim to develop next-generation imaging systems and technologies by integrating imaging physics, computational methods, and advanced detector technologies, ultimately making CT more accurate, quantitative, and informative.
