My research centers in the observational study of the high-redshift universe,
including topics like galaxy formation and evolution and the analysis
of the properties of the intergalactic medium. I have developed
techniques for the estimation of photometric redshifts, and
applied them to deep photometric surveys like the Hubble Deep Fields,
and large area surveys like ALHAMBRA. The application of those same
techniques to Gamma-Ray Burst afterglows has led to the discovery of
some of the most distant objects in the Universe.
