John Welch

Dr. John Welch is an Associate Professor in the Department of Genetics at the University of Cambridge. He retrained as a biologist after initial careers in music and programming, bringing interdisciplinary expertise to his work in mathematical population genetics and evolutionary inference.

• Affiliation: Department of Genetics, University of Cambridge
• Contact: j.j.welch@gen.cam.ac.uk

His research focuses on evolutionary genetics, particularly:

• Evolution of reproductive isolation and hybridization dynamics
• Evolutionary inference from microbial pathogen genomes

He integrates theoretical models with empirical genomic data to study molecular evolution, adaptive responses, and gene interactions across species. The Welch Group website provides further details on ongoing projects.

Dr. Welch takes PhD students and has held postdoctoral positions at University of Sussex, University of Edinburgh, and Université de Montpellier.
