Read bio

Andrea Ballabio was born in Naples, Italy on January 27th, 1957. After his graduation in Medicine in 1981 from the University of Naples, Italy, he took residency training in Pediatrics at the same. He has spent several years working in the field of genetic diseases – first in Italy, then in the UK, and subsequently in the USA where he held the positions of Associate Professor of Molecular Genetics and Co-director of the Human Genome Center at the Baylor College of Medicine in Houston, Texas. He is the founder and director of TIGEM in Naples, Italy. He is also Professor of Medical Genetics at the Faculty of Medicine of the University of Naples “Federico II” and Professor of Molecular and Human Genetics at Baylor College of Medicine in Houston, Texas.

Prof. Ballabio’s research interests are the elucidation of the biological mechanisms underlying genetic diseases, using both traditional and state of the art genomic approaches, and the development of innovative therapeutic approaches. Prof. Ballabio’s team has identified numerous genes whose mutations cause human inherited diseases, leading to the unraveling of their pathogenetic mechanisms. His contributions to gene mechanisms in health and disease are found in X-inactivation (XIST), axonal targeting (Kallmann s.), melanosome biogenesis (ocular albinism), mitochondrial biogenesis (hereditary spastic paraplegia), post-translational protein modification (multiple sulfatase deficiency) and the role of autophagy in lysosomal storage diseases.

He coordinated the development of the expression atlas of the human genome. Among his recent and major discoveries is the identification of a gene network regulating lysosomal biogenesis and autophagy and modulating cellular clearance. He has published over 270 papers in prestigious, international scientific journals. Prof. Ballabio was the President of the European Society of Human Genetics and is currently a Council member of the European Molecular Biology Organization().

He is a recipient of an Advanced Investigator Grant from the European Research Council (ERC). He has received numerous national and international awards for research and culture, among them the 2007 Award of the European Society of Human Genetics. In 2007 he was appointed “Commendatore of the Italian Republic” by the President of Italy Giorgio Napolitano.

Dr. Vilageliu obtained her PhD in Genetics from the University of Barcelona in 1981. In 1985 she was named Associate Professor of Genetics at the Department of Genetics, Faculty of Biology, University of Barcelona. In 2003, she was made a Full Professor in Genetics at the same University. She took a sabbatical at the Department of Biochemistry of the University of Oxford (U.K.) from 1990 to 1991.

In 1992, she and Dr. Daniel Grinberg co-founded a research group for the study of the genetic basis of lysosomal storage disorders. The studies included the identification and characterization of mutations for several lysosomal diseases. At present, they are focused on the development of cellular models and different therapeutic approaches for these disorders, in particular, Sanfilippo C syndrome, for which they have established a human neuronal cell model through the generation of iPS cells. The therapeutic strategies are based on the use of siRNAs and shRNAs, chaperones, aminoglycoside antibiotics and antisense oligonunucleotides, depending on the type of mutation to be treated. This research has been acknowledged and supported by several national and international agencies, among them: the Spanish “Ministerio de Educación y Ciencia” and “Ministerio de Ciencia e Innovación”; “Generalitat de Catalunya”; “CIBER de Enfermedades Raras (CIBERER)”; “Fundación Niemann-Pick de España”; “Federación de asociaciones de Mucopolisacaridosis y síndromes relacionados” and the “Jonah’s Just Begun- Fundation to Cure Sanfilippo”.
