Sérgio Laranjo

Docente Professor Auxiliar
Investigador Principal; Diretor Académico do Centro de Conhecimento de IA, RWE & Saúde Digital; e Vice-Diretor do D³@NOVA

Sérgio Laranjo é cardiologista pediátrico consultor e professor assistente na NOVA Medical School, dedicado a transformar a medicina cardiovascular através da inteligência artificial, métodos computacionais e inovação em saúde digital. O seu trabalho clínico e académico centra-se na melhoria da precisão diagnóstica e dos resultados terapêuticos em diversas populações de doentes, com especialização em arritmias cardíacas, disfunção autonómica e cardiologia pediátrica.

No Hospital de Santa Marta, Unidade Local de Saúde São José, lidera serviços clínicos especializados, incluindo a Secção de Arritmologia Clínica Pediátrica, o Programa de Reabilitação Cardíaca e a Unidade de Síncope.

Na NOVA Medical School, é também diretor académico do Centro de Conhecimento em IA, Evidência do Mundo Real e Saúde Digital e Vice-Diretor do Instituto de Design de Dados Digitais (D³@NOVA). O seu programa de investigação integra inteligência artificial para diagnóstico cardiovascular, cardiologia computacional e modelação avançada, imagiologia eletrocardiográfica (ECGi), gémeos digitais para medicina personalizada e metodologias de processamento de sinais para avaliação autonómica. Está empenhado na implementação ética e responsável da IA, abordando o viés algorítmico, garantindo a transparência e priorizando a utilidade clínica através de uma validação rigorosa e do design da interface homem-computador.

O seu trabalho traduz inovações tecnológicas de conceitos de investigação em realidade clínica, com impacto mensurável nos resultados dos pacientes. É autor de mais de 60 publicações revistas por pares e recebeu vários prémios nacionais e internacionais. Além disso, é membro da Sociedade Europeia de Cardiologia (FESC) e do Colégio Americano de Cardiologia (FACC), faz parte do conselho do Grupo de Trabalho da AEPC sobre Genética, Ciência Básica e Doenças Miocárdicas e representa o Centro Nacional de Referência para Cardiopatias Congénitas na rede ERN GUARD-Heart.
