   Ten Bird Genomes Project, 2019/2020

      Ten UTSC undergrad honour students each sequenced, assembled and annotated the genome of a different Canadian bird. People from left to right. Front row: POS1, Adam El-Menini, Arsham Javaherdashti, Yahye Abdi, Amanda Nelson, Abdul Afzal, Shawanah Rahman, Vethushan Ramalingam. Back row: POS1, Else Mikkelsen (Project Coordinator), Jason Weir (Project Principal Investigator), Vernon Fong.
