Ángel Raya

Director of the CMRB

Angel Raya holds an MD and a PhD from the University of Valencia. He pursued postdoctoral training at the Instituto de Investigaciones Citológicas (currently, Centro de Investigación Príncipe Felipe) in Valencia, from 1995 to 2000.

He then was a Research Associate (2000-2004) and a Senior Research Associate (2004-2006) in the Gene Expression Laboratory of the Salk Institute for Biological Studies, La Jolla, CA (USA).

He returned to Spain in 2006 as an ICREA Research Professor. He was CMRB´s Scientific Coordinator until 2009, when he joined the Institute for Bioengineering of Catalonia (IBEC) as group leader of the Control of Stem Cell Potency Group.

In 2014 he was appointed Director at CMRB.

He studies the tissue, cellular and molecular mechanisms that determine the regenerative response in certain species of vertebrates, as well as the genetic and epigenetic mechanisms that control cellular reprogramming.
