RESEARCH TRACK RECORD

My research focusses on probing the strong-field dynamics of spacetime with gravitational waves, in particular from merging compact binaries composed of neutron stars and/or black holes. Highlights from my early career include: • I helped prove that axisymmetric, but otherwise arbitrarily deformed black holes can be characterised by multipole moments defined at the horizon itself, without reference to even a small neighborhood of it (2004). • As a postdoc, I showed that exploiting the full structure of gravitational waveforms from binaries, including higher harmonics, can dramatically improve parameter estimation (2006). • I helped demonstrate that this in turn would allow for studying the dark energy equation of state with space-based interferometers (2007). I also pioneered studies on cosmology with third-generation ground- based observatories such as Einstein Telescope (2010). • I led the first explorations towards including precessing spins in search pipelines for binary black holes (2006-2009).

At Nikhef, I initiated several lines of research: • I developed the first data analysis pipelines to test the genuinely strong-field dynamics of general relativity (GR) with coalescing binaries. This prompted the establishment of a dedicated LIGO-Virgo working group in 2012, and tests of GR with the first gravitational wave detection led to one of the most cited LIGO-Virgo papers of 2016. • Observations of gravitational waves from binary neutron star mergers will allow us to determine the elusive neutron star equation of state, which is one of the main open problems in astrophysics. With my group I have been spearheading the development of concrete data analysis methods, having set up the first data analysis pipelines for equation of state measurements in 2013. • My group has been playing a key role in using binary coalescences as “standard sirens” for cosmology with LIGO and Virgo, in particular measuring the Hubble constant with or without electromagnetic counterparts to the gravitational wave signals. • Alternatives to black holes (boson stars, dark matter stars, possibly quantum modifications of black holes) will leave a signature in their gravitational wave emission through tidal effects, resonant excitations, violations of the black hole no-hair theorem, and/or gravitational wave “echoes”. I am among the leaders in the development of data analysis methods to search for such anomalies.
