My name is Jay Hyun Jo, and I am a postdoctoral associate working on neutrino and dark matter physics at Wright Laboratory, Yale University in New Haven, CT.

Before joining Yale University, I received Ph.D. in physics from Stony Brook University in 2015, and B.S. degree in physics from Seoul National University in 2009. My doctoral thesis was on measurement of electron neutrino interaction rate on water using Pi0 detector in T2K experiment. The paper based on my thesis work can be found here.

I’m now working in the Maruyama Group on dark matter experiment, DM-Ice. DM-Ice is a NaI(Tl) direct detection dark matter experiment to test DAMA’s assertion that the observed annual modulation is due to dark matter. The collaboration has deployed ~100 kg of NaI detectors at Yangyang Laboratory in South Korea, together with KIMS-NaI group under the name of COSINE-100 experiment. These detectors started taking data in September 2016, and many physics analyses are very actively on-going. I played a key role in every facet of the detector commissioning, data production, and physics analyses. I’m currently leading the modulation analysis working group to produce COSINE-100’s primary physics result, a measurement of the dark matter signal induced by annual modulation.

I also recently joined Prof. Bonnie Fleming’s group to work on the MicroBooNE experiment at Fermi National Accelerator Laboratory, a liquid argon time projection chamber (LArTPC) neutrino experiment that will investigate 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. I’m working with a team at Brookhaven National Laboratory to develop a novel track reconstruction algorithm, known as Wire-Cell tomographic imaging.

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