I am an associate professor in the gravity group at UIB - the University of the Balearic Islands, where I carry out research in general relativity - Einstein's theory of gravitation - and teach undergraduate and graduate students.

Coming out of a mathematical relativity background at the University of Vienna, my research focuses is on what I believe is today's most exciting challenge in spacetime physics - to connect the beautiful theory of the strong field regime of general relativity with astrophysical observations. Most of my work concerns applying the methods of computational physics to study gravitational waves from black holes.

I am a member of the international society on general relativity and gravitation and the Spanish society for gravitation and relativity.

Research interests:

Much of the input to gravitational wave data analysis and the astrophysics of black hole binaries has relied on analytical approximations to
solutions  of the Einstein equations, in my research I solve the full Einstein equations with numerical methods, and I investigate how this can improve the science output of astrophysical observations. This aim also calls for further improvements in the understanding of numerical and analytical techniques to solve the Einstein equations.

Some of my current research topics:
  • Accurate numerical evolutions allow to test post-Newtonian approximations, and by matching to post-Newtonian inspiral results, to describe the complete evolution and gravitational wave signal of a black hole binary. Crucial difficulties are in obtaining overall error estimates and requirements for gravitational wave data analysis, and in representing the full parameter  space of precessing binaries.
  • Physically accurate initial data for black hole spacetimes
    • construction of low-eccentricity black hole binaries, which are very common in astrophysical scenarios,
      see e.g. PRD 77:044037, 2008.
    • controlling the radiation content, this requires using non-conformally flat initial data,
      see e.g. CQG. 24:S15-S24,2007.
  • For numerical evolutions it is beneficial to exploit explicitly time-independent slicings of spacetime, in many interesting cases these have however not yet been constructed, and the full implications of available solutions is not yet fully explored,
    see e.g. PRL 99:241102, 2007, PRD 78:064020,2008, CQG 26:175014, 2009.
  • Analytical template banks for gravitational wave signals, which "interpolate" full numerical solutions,
    see  e.g. PRD 77:104017, 2008 arXiv:0909.2867.
  • The NINJA project is a community effort to systematically test codes to search for gravitational waves from binary inspirals by injecting waveforms obtained from numerical solutions of the full Einstein equations into the noise of gravitational wave detectors.
Much of my research is carried out in collaboration with Mark Hannam @University of Vienna, the BAM developers @ University of Jena and Parameswaran Ajith @ Caltech.
