Fiona Nielsen, founder of DNAdigest and Repositive, is a bioinformatics scientist turned entrepreneur. At Illumina she was developing tools for interpretation of next-generation sequencing data and analysing cancer and FFPE samples sequenced on the latest technology. There she realised how difficult it is to find and get access to genomics data for research, which led to DNAdigest being founded as a charity to promote best practices for efficient and ethical data sharing - aligning the interests of patients and researchers. In August 2014 Repositive Ltd was spun out of DNAdigest as a commercial entity to develop and provide a novel software tools and mechanisms for sharing of data. Repositive has since grown to the biggest portal for accessing public genomic data sources, contributing expertise and genomic search functionality to the NIH Data Commons. Repositive is on a mission to fuelling the precision medicine revolution by unlocking access to genomic assets across the world. Fiona was nominated for the 2013 WiSE award for Entrepreneurship and Innovation.
