My research aims to address some of the most fundamental questions about our Universe: Why does matter dominate over antimatter? What are the properties of neutrinos? Are there additional neutrino flavors? And what constitutes the invisible universe?

To explore these questions, I develop and utilize cutting-edge detector technologies based on the Liquid Argon Time Projection Chamber (LArTPC). At Brookhaven National Laboratory, I lead efforts in developing advanced neutrino event reconstruction algorithms—most notably the Wire-Cell tomographic imaging technique—used in the MicroBooNE experiment and now being extended to next-generation detectors such as DUNE.

Before joining BNL, I worked on dark matter direct detection with the COSINE-100 experiment at the Yangyang Underground Laboratory and on neutrino interaction studies with the T2K experiment at J-PARC.
