Speaker: Alvin X. Han. BIO: Alvin X. Han, PhD is a bioinformatician and infectious disease modeller with broad interests in virus evolution and epidemiology. He is currently based in the Department of Medical Microbiology and Infection Prevention at Amsterdam University Medical Center in The Netherlands. He has worked with a variety of viral pathogens but his core interests mostly center around influenza viruses and more recently, SARS-CoV-2. He analyse viral genomes using phylogenetic methods, build mathematical models as well as other computational tools to elucidate the processes underlying how viral pathogens evolve and spread through the human population. Since 2021, he has also been one of the key modelling contributors to the World Health Organization and Foundation for Innovative New Diagnostics (FIND)’s Access to COVID-19 Tools Accelerator (ACT-A) SARS-CoV-2 diagnostics modelling consortium that focuses on quantifying the impact and optimising the use of COVID-19 rapid antigenic diagnostic tests in low and middle income countries. His work has been published in Nature Ecology & Evolution, Molecular Biology and Evolution, and eLIfe, among others.
