My name is Thomas Walsh and I’m a bioinformatician in the CNIO Bioinformatics Unit. My main focus is on maintenance and further development of the APPRIS system for identifying principal gene transcripts in human, mouse and a range of organisms.

Before arriving at the CNIO, I spent some time working at Ares Genetics GmbH in Vienna, Austria. While there, I worked on tools and techniques to support the battle against antibiotic resistance.

Prior to that, while working at the Centre for Genetic Architecture of Complex Traits (GACT) at the University of Leicester, I focused on QTL analysis in S. cerevisiae with individual or pooled samples, as well as genotyping of single‐nucleotide variants using next‐generation sequencing data.

My formative period in bioinformatics was in the O’Connell lab while at Dublin City University, where I investigated the evolution of placenta‐specific genes in Eutheria, identifying genes specific to placenta that were either under selective pressure in their coding sequence or contained microRNA target sequences in their untranslated regions.
