João Pedro Casanova Prazeres concluiu a Licenciatura em Engenharia Eletrotécnica e de Computadores em 2018/07 e o Mestrado em Engenharia Eletrotécnica e de Computadores em 2020 pela Universidade da Beira Interior. A defesa da sua tese "Static Point Clouds Compression efficiency of MPEG point clouds coding standards: A practical comparisonbetween two powerful PCC codec's" foi avaliada com 19 valores. Participou em várias conferências internacionais como ICASSP, ICIP e ACM. Recebeu 1 prémio para melhor artigo na conferência EI 2022. Participou como Bolseiro de Doutoramento no projeto interno do Instituto de Telecomunicações PLIVE. Atualmente encontra-se bastante envolvido na JPEG, nomeadamente na atividade JPEG Pleno Learning Based Point Cloud Coding, onde apresenta frequentemente contribuições relacionadas com avaliação de qualidade.
