In my Ph.D. research I develop numerical techniques to simulate strongly relativistic spacetimes with a particular focus on spinning black holes and neutron stars in binary configurations for detection by current and future gravitational wave observatories. To this end, I work with the [Simulating eXtreme Spacetimes (SXS) collaboration] on the next-generation pseudo-spectral numerical relativity code [SpECTRE]. It incorporates nodal discontinuous Galerkin methods, task-based parallelism and adaptive mesh refinement to dynamically resolve neutron star matter and distribute computation to supercomputers with thousands of CPUs and more. Currently, my main area of research is the development of numerical schemes to solve the elliptic partial differential equations that appear in general relativistic initial data problems.

My Ph.D. supervisor is Prof. Dr. Harald Pfeiffer.
