RESEARCH INTERESTS

My work is focused on numerical solutions of Einstein's equations, describing processes such as binary black hole and neutron star collisions. The outcome of these kind of simulations is considered to be crucial for the successful detection and interpretation of gravitational waves, expected to be measured by laser interferometers such as LIGO, GEO600, LISA and others. In turn, measurement of gravitational waves will constitute a strong, direct verification of Einstein's theory, and open a new window to the universe. The construction of these numerical solutions requires large scale computations and research on a variety of physical, mathematical, numerical and scientific computing issues, on which I am involved.
