Research Interests

  • Physical and Observational Cosmology
  • Structure Formation in the Universe
  • Dark Matter
  • Clusters of Galaxies
  • Gravitational Lensing
  • Sunyaev-Zel'dovich Effects
  • Cosmic Microwave Background
  • Plasma Physics
  • Statistical Methods: Bayesian and Frequentist Approaches
  • Backward and Forward Modeling
  • Radio Interferometry

My research interests and experience encompass the fields of observational cosmology and astrophysics, with the goal of understanding the nature of dark matter and its role in cosmic structure formation. To this end, my research is primarily centered on galaxy clusters, the largest class of cosmic objects to have formed in the universe, and their surrounding large scale structure by using gravitational lensing in combination with theoretical modeling and complementary data sets from Sunyaev–Zel’dovich effects, X-ray, and dynamical observations.
