Biographic notes
I conduct a wide range of observations and use different telescopes (e.g. VLT, Subaru, CFHT, UKIRT, INT, WHT) in order to understand how galaxies like our own formed and evolved from the primitive Universe till today. I have conducted by far the largest H-alpha surveys (and recently Lyman-alpha) spanning the bulk of the history of the Universe. I'm particularly interested in star-forming galaxies. In 2012 I was awarded a 3-year, 250k EUR Veni fellowship/grant by NWO, followed by a FCT Investigator (2012) 5-year Starting Grant at CAAUL/FCUL in late 2013.
