My interests in physics started at a very young age and astroparticle physics grew to be of particularly fasinating. The origins and acceleration mechanisims of the highest energy particles in the Universe are among the most enduring mysteries of modern physics.

During PhD I was at the University of Leeds (United Kingdom) and University of Wuppertal (Germany) to search for ultra-high energy photons using data from the Pierre Auger Observatory.

I am now a postdoc researcher and working for the IceCube Neutrino Telescope.

A list of topics I have been working on

  • Search for ultra-high energy photons using timing information from surface detectors at the Pierre Auger Observatory
  • PeV energy Partially-contained Events (PEPE) search with IceCube
  • Extremely High Energy (EHE) neutrino online alert for IceCube
  • In-ice hadronic cascade searches and reconstructions
  • Dual-PMT optical module (D-Egg) for IceCube Gen2

Research Interests

Where are the highest energy particles from?
γ

Photons

From X-ray, gamma-ray to UHE photons, they carry key information on the UHE sources. Difficulty: Universe is opaque and there are leptonic sources.

ν

Neutrinos

Neutrinos are weakly interactive and ideal for astronomy. My prime interests are PeV astrophysical neutrinos and EeV cosmogenic neutrinos.

CR

UHECR

A more than 100-year mystery but hard to solve because the charged particles bend in B fields. Mass composition unknown and highly diffused.

Multi-Messenger-Astronomy

The most promising way to find the first UHE sources.
