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 (MRSA), under the supervision of Ed Feil, at the University of Bath in England. Santiago is Associate Professor in the Evolutionary Genomics Research Program at the CCG. His research focuses on diverse aspects of the micro evolution of bacterial pathogens, including phylogeography and evolutionary genomics. Although his initial work concentrated on the molecular evolution and the phylogeography of MRSA 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 nosocomial pathogen) and closely related species.
To date Santiago has published 46 articles, which have more than 1650 citations and his has an h-index of 20 and i10-index of 28. He is Associate Editor of the journals Plos Neglected Tropical Diseases and Frontiers in Microbiology; he is also member of the editorial board of Applied Environmental Microbiology. He has served as reviewer for over 20 journals, among them PNAS, Genome Research, Molecular Biology and Evolution, and Lancet Infectious Diseases. Additionally, he has acted as a reviewer for grant agencies in Mexico (National Council for Science and Technology), Canada (NSERC Discovery grants) and United Kingdom (Medical Research Council, Fellowships scheme). He has supervised a couple of postdocs, graduated one PhD student and two undergraduate students. At the present time, he supervises one postdoc, one PhD student and one Master student.
Currently, together with Michael Gillings and Timothy Ghaly (from Mcquarie University), we are leading the special issue “One Health & Antimicrobial Drug Resistance” (see link below) for Environmental Microbiology. https://sfamjournals.onlinelibrary.wiley.com/pb-assets/assets/17582229/2020-one-health_EMI-EMIR-1608325039767.pdf
Recently, he was the Lead Editor of the research topic “Genomic Basis of Antibiotic Resistance and Virulence in Acinetobacter” for Frontiers in Microbiology. https://www.frontiersin.org/research-topics/12244/
He has several ongoing international collaborations, listed below:
1) Together with Scott V. Edwards at Harvard University, we are studying the evolutionary dynamics of Mycoplasma gallisepticum.
2) Along with Ben Evans from University of East Anglia, Ayush Kumar (University of Manitoba) and Izhar Kahn (Agriculture and Agri-Food Canada), we are studying environmental isolates of A. baumannii.
3) In collaboration with Gabrielle Margos from the German National Reference Centre for Borrelia, we have been describing the phylogeography of several Borrelia species.
