Teaching Activity

A. Marcello is co-organizer of the ICGEB Workshop on Human RNA Viruses held bi-annually around the world (2008, Trieste – Italy; 2010, New Delhi – India; 2012 Buenos Aires – Argentina). He is Professor of Molecular Biology at the University of Nova Gorica, Slovenia, since 2010. His teaching activity is focused on Virology, Microbiology, Molecular Biology and Functional Genomics through courses or seminars at various universities and institutions. He regularly trains PhD students in the laboratory and is an external member of the Doctorate of Molecular Biomedicine of the University of Trieste. During his career he was nominated in several national and international PhD examination panels.

Scientific Activity

A long-standing interest in host-virus interactions has driven A. Marcello's research. He strongly believes that the molecular dissection of virus-host interactions is not only relevant to the understanding of viral pathogenesis, but it is also extremely useful for the characterization of fundamental cellular processes that are exploited by the virus. Current research in the lab aims at identifying the key cellular and viral factors that control infection of viruses such as the human immunodeficiency virus (HIV), the tick-borne encephalitis virus (TBEV) and hepatitis C virus (HCV). A wide array of molecular biology techniques are being implemented in the laboratory, including highly innovative fluorescent optical tools to visualize intra-cellular processes that control the virus life cycle in living cells. Work in the lab also focuses on virus diagnosis and antivirals through collaboration with industrial partners and various laboratories also in developing countries. Research activity is funded through grants from various public and private bodies, including the Human Frontiers Science Program, the European Commission and the Italian institute of Health among others, as well as through collaborations with companies.

A. Marcello is member of the editorial board of Retrovirology and PLOS One and reviews scientific manuscripts for international journals in the fields of virology and grant applications in the context of calls from various granting bodies in Europe. He presents regularly his research activity at international meetings and seminars.
