About Me

 

     

I joined the Dean's office at the Harvard John A. Paulson School of Engineering and Applied Sciences as the Executive Director for Education and Research in July 2014.  As of 2016, I am also serving currently as the Executive Vice Provost for Strategic Initiatives at the Universidad de Ingenieria y Tecnologia in Peru.

Between 2005-2014, I was a professor in the Harvard Astronomy Department (Associate Professor 2009-2014; Assistant Professor 2005-2009) which is part of the Harvard-Smithsonian Center for Astrophysics.  I did my postdoctoral work at MIT under the auspices of the NASA-Chandra Postdoctoral Prize Fellowship.  I hold a Ph.D in Astrophysics from Cambridge University, U.K. (1996-2000) and B.S. degrees in Mathematics and Astrophysics (1990-1994) from UCLA.  I also spent two years prior to graduate school as a core member of the Supernova Cosmology Project research team at the Lawrence Berkeley National Laboratory Institute for Nuclear and Particle Astrophysics. Continuing collaborations with this group ultimately led to a co-authorship on the discovery paper for cosmic acceleration (by a dark energy force) for which the 2011 Nobel prize in Physics was awarded to the team leads.   Along with other team members, I shared in the 2007 Gruber Cosmology Prize and the 2015 Breakthrough Prize in Fundamental Physics.

My current research primarily makes use of X-ray spectral diagnostics to study plasma conditions in space under extreme temperature and density conditions. My research program uses a combination of laboratory experiments at (inter)national synchrotron facilities and multi-wavelength space-based observations to study the range of topics from black hole dynamics to the composition and distribution of cosmic dust.
