Ralf Konietzka's research focuses on cosmology and extragalactic astronomy, with a specific emphasis on Fast Radio Bursts, a new class of cosmological transients.  
  
Using a combination of numerical simulations, analytic theory, observations, and data science, he investigates how we can use Fast Radio Bursts as cosmological probes to study the evolution of our Universe.
