Arsénio M. Fialho

Associate Professor with Habilitation


Research Activities

His research is focused on the study of bacterial proteins as novel anticancer agents. Studies aiming to elucidate the cellular and molecular effects of treating cancer cells with azurin, a cupredoxin produced by P. aeruginosa. His research interests also include the study of trimeric autotransporter adhesins as key virulence determinants in members of the Burkholderia cepacia complex, a group of bacteria that have emerged as opportunistic pathogens among individuals with cystic fibrosis.
