Experience

  • August 2019 – January 2021: DST INSPIRE Faculty Fellow – Indian Institute of Science, Bengaluru, India.
  • Decenber 2016 – July 2019: Postdoctoral Fellow – High Energy Accelerator Research Organization (KEK), Tsukuba, Japan.
  • November 2014 – December 2016: Postdoctoral Fellow – Tata Institute of Fundamental Research, Mumbai, India.

Research Interest

  • My broad research interest is to study the phenomenology of physics beyond the Standard Model (BSM) - in particular, collider search strategies and prospects of different BSM models at the Large Hadron Collider and future proposed collider experiments. The aim is to build new theoretical models/frameworks and device new search strategies in order to improve our knowledge of the SM Physics processes as well as BSM physics signatures.

    A few topics of my current and future research interests include:

    - Standard Model and Beyond Standard Model Physics
    - Higgs Boson Physics and Phenomenology of Multi-Higgs models
    - Flavour Physics and Dark Matter at the Colliders
    - Jet-substructure and Machine Learning techniques in Jet Physics.
    - Ultra-light particles and Physics Beyond the Colliders
