Academic Role: Postdoctoral Researcher
Biography: Marc Mejias (Barcelona, 1978) earned his Bachelor’s of Science degree in Biology from the University of Barcelona in 2003 and his Ph.D. degree in Biology from the University of Barcelona in 2010. He was awarded with a Predoctoral Fellowship from the Spanish Ministry of Science. Furthermore, his doctoral thesis entitled “Role of angiogenesis in the pathophysiology of portal hypertension”, directed by Mercedes Fernandez, received the Excellent Cum Laude qualification and was awarded with the University of Barcelona Extraordinary Doctorate Prize for the academic year 2009/2010. He has also earned the professional Certificate in Training on Experimental Animal Use and Design of Research Projects of the University of Barcelona (2003), the Certificate in Introduction to Flow Cytometry from IDIBAPS (2016), and participates in the oficial IDIBAPS Training Programme for Pre and Postdoctoral Researchers (from 2016). He also participated as a Faculty Member in the Basic School of Hepatology of the European Association for the Study of Liver (Barcelona, October 2018).
