Dr Javier Caceres is a Principal Investigator at the MRC Human Genetics Unit (MRC HGU) in Edinburgh. He studied for both his BSc and PhD in Molecular Biology at the University of Buenos Aires in Argentina. In 1989, he moved to the USA to carry out postdoctoral research in the laboratory of Jim Dahlberg (University of Wisconsin-Madison), where he studied transcriptional control. In 1991, he joined Adrian Krainer’s laboratory at Cold Spring Harbor, where he worked on alternative splicing regulation. He joined the MRC HGU in 1997, where his laboratory has focused on different aspects of RNA processing, including alternative splicing regulation, nonsense-mediated decay and microRNA biogenesis. He has served on numerous international reviewing panels and editorial boards. He was elected as a member of the European Molecular Biology Organization (EMBO) in 2008.
