About Me

I am working on Dark Matter Model Building!

My Passion

I am a 3rd-Year PhD Student studying theoretical particle phenomenology and astroparticle physics at UCLA. For my research, I use a combination of Quantum Field Theory and Astrophysics to find and better understand the high energy astrophysical phenomena and the nature of dark matters and neutrinos. Broadly speaking, my research draws connections between the model-building of theory beyond the standard model and its astrophysical implications.

Research

Imagine what our universe is composed of ......

  • Extreme Astrophysics

    High energy particle emissions from the active galactic nuclei probe the physics around supermassive black holes and the nature of elementary particle interactions (Image Credit: NASA/JPL)

  • Sogebu Relativity

    We are developing a fully relativistic simulation of electromagnetic fields in a 3D first-person game environment.

  • Gravitational Wave Phenomenology

    Axion-like particles (ALPs) can be detected via future gravitational wave laser interferometry

  • Particle Dark Matters

    Model building for particle dark matter is essential for physics beyond the standard model
