I qualified as veterinarian in 1991. Since then, I have done an MSc in Laboratory Animal Science at The Royal Veterinary College (RVC), a PhD in Molecular Biology working with Coronaviruses at the Autonoma University in Madrid, and a residency in Laboratory Animal Medicine at GSK-UK. In 2005, I passed my Boards and became Diplomate of the European College of Laboratory Animal Medicine (ECLAM). I am also a RCVS Recognised Specialist in Laboratory Animal Science. Early in my career, I had managed a mini pig breeding herd homozygous for SLA (Swine Lymphocyte Antigen). Then, I worked for The RVC and the Medical Research Council National Institute for Medical Research (MRC-NIMR) as Named Veterinary Surgeon (NVS). Later, I have run three laboratory animal care and user programs: at the National Centre for Cardiovascular Research (CNIC) in Madrid, at Trinity College Dublin (TCD), and at the University of Edinburgh. During all these years, I have done some research. In 2003, I described the first case of a non-human primate intersex in the literature. The following year, I published a study on a virulent strain of canine coronavirus (CCoV) describing an important part of the coronavirus genome involved in virulence. During 2009, I published the infection of Xenopus frogs with Mycobacterium gordonae, a zoonotic Mycobacterium. The same year, I published another paper in which I described discrepancies in the diagnosis of Helicobacter spp., a common rodent pathogen, by different laboratories and described for the first time the different constant and variable regions in the 16S ribosomal gene of the genus, providing a new diagnostic assay. I have also been part of the Irish Coronavirus Sequencing Consortium for the recent SARS CoV 2 outbreak (https://doi.org/10.2807/1560-7917.ES.2021.26.16.2100348). I run an ECLAM Laboratory Animal Medicine residency programme from 2011 to 2013. I have also set up the ESLAV's Summer school and Winter school programmes, and a webinar series to act as continuous professional development during 2016 and 2017. I was also part of the Laboratory Animals Editorial Board from June 2014 till October 2020. Since November 2021, I am now one of the five Editors in Chief of the journal. I am series editor for a five-volume monograph on laboratory animal science and medicine published by Springer Nature. I have recently published, as editor and author, the first book of the series on reproducibility of animal research. I am currently Director of Bioresearch and Veterinary Services at the University of Edinburgh.
