My research is founded in the transdisciplinary field of phenomics, where the goal is to develop and validate new methods of measuring phenotypes on animals. We strive to continuously push measurement technology to overcome barriers in 'expensive or difficult to measure traits', by focusing on non-invasive, cost effective, rapid and large-scale measurements. The unifying task is to map the phenome to genome for selective breeding of better animals towards improving food security, animal welfare, sustainable development, and climate change. My research areas span high dimensional data streams such as sensors in time series, NIR and Raman spectroscopy, microbiomics, metabolomics, images and X-rays. Species of particular interest are Atlantic salmon, dairy cattle & sheep. I lead the PhenotypeForge https://garethdifford.com/phenotypeforge
