Today is a discussion of virus evolution with biologist Justin Meyer.
Justin Meyer is associate professor of biology at UC San Diuego.  He received his Ph.D. from Michigan State University and was a Systems Biology Departmental Fellow at Harvard Medical School, where he was awarded the James S. McDonnell Foundation Fellowship for Studying Complex Systems. He joined the faculty of Ecology Behavior and Evolution and the Quantitative Biology Initiative in 2014.  His lab studies changes to viral genomes which allow them to infect new species--And, the natural processes – mutation, recombination, and natural selection – that permit their evolution.
