Hi, welcome to my webpage. I am a researcher of particle physics, also known as high energy physics. I mainly work on the theoretical aspects of physics beyond the Standard Model.

Big picture

Despite the established frameworks provided by the Standard Model of particle physics for fundamental forces and matter, and the Lambda CDM model for cosmic evolution, overwhelming observational evidence suggests we must develop theories beyond these models. Physics in the particle world is deeply connected to the mysteries of the universe, and finding new physics is crucial for understanding our universe!
As a researcher specializing in particle physics, I focus on theoretical aspects of physics beyond the Standard Model while looking for hints through various cutting-edge experiments; from underground to outer space, from the extremely precise machines to the gigantic colliders.

Recently, I have been using Big Bang Nucleosynthesis and other cosmological probes to study new physics. One example is the boundary between the early universe and particle and hadron physics, where we derived new bounds on heavy QCD axions. I am now extending this direction to dark matter and neutrinos. I am also interested in applying condensed matter systems and machine learning to particle physics research.

I regularly give outreach lectures at my university through Saturday Morning Physics and also am open to speaking at local schools.

Research Interests

1. Physics Beyond the Standard Model
2. Phenomenology of particle physics and cosmology

Topics I work on

• Early universe: long-lived particles, dark matter, and neutrinos through Big Bang Nucleosynthesis and other cosmological probes
• Flavor physics from kaon and B-meson experiments
• Collider physics: the Higgs boson and future colliders
• New approaches: applications of condensed matter systems and machine learning to particle physics
