Tamás Arányi, MD, PhD, obtained his medical degree at the Semmelweis University, Budapest, Hungary in 1998. He followed his studies in Paris, France at the University Pierre et Marie Curie and obtained his PhD degree in 2003 in molecular neuroscience. He then joined professor András Váradi’s laboratory at the Institute of Enzymology, Hungarian Academy of Sciences as a postdoctoral fellow. Since then he has been interested in the transcriptional and epigenetic regulation and evolution of the human ABCC6 gene as well as its association with clinical phenotypes. He published several papers in the field, presented his data at the PXE research meeting in 2004, twice at the Annual North American ABC Research Meeting and three times at the biannual FEBS ABC Special meeting. He attended some of these meetings with a PXE fellowship and was a PXE fellow in 2004-2005. Currently he is a senior research fellow and supervises the PhD studies of Hugues de Boussac and the work of Dr. Caroline Bacquet, postdoctoral fellow in professor András Váradi’s laboratory.
