Regular biography
John Welch is a Fellow at the University of Cambridge, affiliated with the School of Biological Sciences. His research focuses on evolution, population genetics, quantitative genetics, phylogenetic comparative methods, and speciation. He employs phylogenetic and comparative methods to infer past evolutionary events from genomic sequence data, aiming to understand the processes shaping DNA sequence variation within and between populations. His work integrates mathematical modelling and phylogenetic comparative methods to explore evolutionary mechanisms.
Scholar-generated biography
John Welch is a Lecturer in the Department of Genetics at the University of Cambridge, specializing in evolutionary biology and population genetics. His research explores the genetic mechanisms underlying evolutionary processes, including the dynamics of molecular evolution, adaptive evolution, and the role of population structure in shaping genetic diversity. Welch's work often integrates genomic data with phylogenetic and population genetic methods to investigate topics such as host-parasite interactions, hybridization, and the evolution of microbial symbionts. His studies have contributed to understanding the genetic basis of adaptation, the spread of antibiotic resistance, and the evolutionary history of species through environmental DNA analysis.
