Education

I obtained my Licenciatura in Physics in 1993 at the National University of Cordoba (Argentina). In 1994 I moved to the University of Pittsburgh (USA) where I obtained my PhD in February 1998. I then held postdoctoral fellowship positions at the University of Texas at Austin (1998-2000) and the University of British Columbia (2000-2002)

Professional Experience

I joined Louisiana State University in 2002 as an Assistant Professor and was promoted to Associate Professor in 2006. In 2009 I moved to southern Ontario to a joint Associate Professor position at the University of Guelph and an Associate Faculty position at the Perimeter Institute for Theoretical Physics.

Professional Activities & Awards

Since 1998 I have acted as reviwers of publications at several of the most prestigious journals in theoretical physics. I have also acted as external and panel reviews for diverse funding agencies (USA, Canada, Israel, Austria) and been PhD defense committees in the USA, India and Australia. Since 2003 I have been a member of the Editorial Board of Classical & Quantum Gravity (one of the most prestigious journals in Gravitational theory); have served since 2007 as a member of the Science Advisory Board to the NSF-Teragrid (USA) and Committee Member for electing the Nicholas Metropolis Awardee since 2008. I was elected as Member at Large to represent the Topical Group of Gravitation (2009). I am a Fellow of the Institute of Physics (UK), was a Sloan Fellow (2005-2007) and Kavli-National Science Foundation Fellow (2008).

I am recipient of several distinctions: Honor Prize (National University of Cordoba, 1993), Council of Graduate Schools Distinguished Dissertation Award (1998); American Physical Society Nicholas Metropolis Award (1999); Phi Kappa Phi Non-Tenured Faculty Award in Natural and Physical Sciences (Louisiana State University, 2004); was named one of Baton Rouge Business Re­ports’ “Top Forty Under Forty” in 2007 and one of Louisiana State University’s “Rainmakers” in 2008.

Research Activities

My field of research is General Relativity and my work concentrates on describing strongly gravitating/highly dynamical systems like those containing black holes or neutron stars. These systems are copious producers of so far elusive gravitational waves. These waves predicted to exist by General Relativity are extremely difficult to detect due to their weak character when they reach earth or its vicinity. Recently, a number of highly sensitive detectors in the USA, Germany and Italy have been built to detect such waves and interpret their physical significance. Since gravitational waves travel unscattered through space, they provide pristine information of the source that produced them. Furthermore, future detectors will be able to detect waves produced close to the beginning of our universe. Decoding the information carried out by these waves, will likely have a profound influence in our understanding of fundamental physics and the cosmos. My research focuses on providing the link between signatures of these waves and the source that produced them. This information is used to understand the system that produced but also to enhance the likelihood of detection of their signals.
