My research probes the most fundamental aspects of the nature of matter and energy. In particular, I am engaged in the study of neutrino flavour oscillation, which is the first discovery that lies outside the current predictions of the standard model of particle physics. I work on accelerator neutrino experiments, currently the T2K experiment in Japan as well as the future DUNE experiment in the USA.
I am a proud member of the T2K collaboration, which is the world's leading neutrino oscillation experiment. In 2015–19, I served as International Co-Spokesperson, which means I was one of the scientific leaders of the collaboration of 500 scientists. We send a beam of muon neutrinos from the J-PARC facility in Tokai across the main island of Japan to the Super-Kamiokande detector deep within the Kamioka mine. We are making the world's most precise measurements of the neutrino mass splittings and mixings first observed with atmospheric neutrinos. We have also recently published a stunningly large excess of electron neutrino events allowing us to measure the heretofore unobserved subdominant oscillation and its mixing angle, theta_1-3. These are the next steps toward the goal of searching for CP violation with neutrinos.

I am a member of the DUNE collaboration, which is working to build a new long baseline accelerator neutrino experiment in the USA. This experiment would provide exquisite sensitivity to the search for violation of charge-parity symmetry in neutrinos, which could explain why the universe is made of matter and not antimatter. I am working on the DUNE near detector, specifically the high pressure gas time projection chamber (HPgTPC).

I founded the SciBooNE experiment at Fermilab and served as Co-Spokesperson. We ran a fine-grained tracking neutrino detector in the Booster Neutrino Beam, and have published 12 papers on neutrino oscillation (jointly with MiniBooNE) and measurements of neutrino and antineutrino cross sections near 1 GeV neutrino energy.

I spent 10 years working on the MiniBooNE experiment at Fermilab. MiniBooNE ruled out the discovery of sterile neutrinos by the LSND collaboration in the late 1990s, but found an excess of low energy electron-like events in neutrino and antineutrino data.
