Barton's research is focused on the development and application of computational tools for the analysis of protein sequences and their three-dimensional structures in the context of
evolution to infer structure and function. His work focuses on understanding how
DNA changes impact proteins' three-dimensional structure, function, and role in disease. He developed methods for protein
multiple sequence alignment, and was an early advocate of benchmarks to assess the accuracy and biological relevance of sequence alignment methods through comparison with alignments based on three-dimensional structures. and protein
ligand binding site prediction. His group has developed widely cited software tools and techniques: Jalview (data integration and visualisation workbench on multiple sequence alignments),
JPred (
protein secondary structure prediction), STAMP (alignment of multiple protein three-dimensional structures), and JABAWS (remote execution of software). Barton established the High Performance Computing facility at the University of Dundee in 2001 and the Division of Computational Biology. He is also an amateur
meteorologist and has maintained the Dundee West End Weather Station since 2002. He was interviewed about the link between bioinformatics and weather forecasting by weather presenter
