In the last week of May, we welcomed Edgar Beltrán to the School of Dental Sciences, from the Facultad de Odontología at the Universidad El Bosque in Bogotá, Colombia. Edgar is a visiting PhD student, and will be working on a bacteriophage model of dental aerosols, with the Newcastle Bioaerosols Research Group during his two month visit.
