About me

Hi there! I am an assistant physicist at Brookhaven National Laboratory in Upton, NY.

At BNL, I work in Electronic Detector Group, focusing on answering fundamental questions about our Universe: Why is matter dominating antimatter? Can the proton decay? How do core-collapse supernovae happen? Are there additional neutrino flavors? What is dark matter?

In order to answer these questions, I spend most of my time on the development of new and powerful detector technology, Liquid Argon Projection Chamber (LArTPC). Collaborating with my colleagues here at BNL, I work developing a novel neutrino event reconstruction algorithm, known as Wire-Cell tomographic imaging.

This is me in Bologna, being excited to enjoy pasta and wine!

Before joining BNL, I received a Ph.D. in physics from Stony Brook University in 2015 and a B.S. degree in physics from Seoul National University in 2009. My doctoral thesis was on the measurement of electron neutrino interaction rate on water using Pi0 detector in the T2K experiment, and a paper based on my thesis work can be found here. After my Ph.D. I joined Wright Lab at Yale University as a postdoctoral associate and an associate research scientist in Prof. Bonnie Fleming's group to work on the MicroBooNE experiment at Fermi National Accelerator Laboratory, a liquid argon time rojection chamber (LArTPC) neutrino experiment that investigated the low energy excess events observed by the MiniBooNE experiment, which could be an indication of an existence of a new type of “sterile” neutrino. At Yale, I also worked in the Maruyama group on a dark matter experiment, COSINE-100, a NaI(Tl) direct detection dark matter experiment to test DAMA’s assertion that the observed annual modulation is due to dark matter.

In my spare time, I love to read books and play/listen to music. I’m also an avid fan of New York Yankees.
