Academic history

Santiago received his PhD in Biological Sciences from the Center for Genomic Sciences (CCG) at the National Autonomous University of Mexico, conducting phylogenomic studies of Alphaproteobacteria. He then pursued postdoctoral research in microevolution and phylogeography of methicillin-resistant Staphylococcus aureus at the University of Bath, under the supervision of Professor Edward J. Feil. Santiago is Associate Professor in the Evolutionary Genomics Research Program at the Center for Genomic Sciences. His research focuses on diverse aspects of the evolution of bacterial pathogens, including phylogeography and evolutionary genomics. Although his initial work concentrated on the molecular evolution and the phylogeography of Staphylococcus aureus and Borrelia burgdoferi, his most recent work employs comparative genomics to study the processes underpinning the genomic variation and the dispersal of Acinetobacter baumannii -an important human pathogen, source of many nosocomial infections. To date Santiago has published over 30 articles and 4 book chapters.

He is Associate Editor of the journal Bioscience Horizons, member of the editorial board of Applied Environmental Microbiology and Review Editor for Frontiers in Microbiology. He has served as reviewer for several journals in bacterial genomics (Applied Environmental Microbiology, Genome Biology and Evolution), molecular evolution (Molecular Biology and Evolution, Molecular Ecology, Infection, Genetics and Evolution) and infectious diseases (Lancet Infectious Diseases). Additionally, he has acted as a reviewer for grant agencies in Mexico (National Council for Science and Technology) and Canada (NSERC Discovery grants).
