Robert Carreras-Torres is a research fellow at the Bellvitge Biomedical Research Institute (IDIBELL) in Barcelona since 2018, when he received an MSCA Individual Fellowship. He completed his PhD in Human Genetics in 2014 at the Department of Animal Biology – Anthropology of the University of Barcelona. In 2014-2018, he trained as a Postdoctoral Fellow in the Genetic Unit at the International Agency of Research on Cancer (IARC) of the World Health Organization (WHO) in Lyon. Robert’s professional interests involve the integration of multi-omic layers (phenome, genome, transcriptome, metagenome) for a better understanding of complex traits and diseases and their interaction with the microbiome. Also, the identification of causal relationships using novel Mendelian randomization or similar statistical approaches for a better risk prediction assessment at individual and population level.
