Nicolas Julien Fossat

Nicolas Julien Fossat serves as an Associate Professor in the Department of Immunology and Microbiology at the Faculty of Health and Medical Sciences, University of Copenhagen. His research spans virology, RNA biology, and developmental biology with a particular focus on viral-host interactions and molecular mechanisms of disease.

His research interests primarily focus on RNA biology and virology, with significant contributions to understanding viral RNA modifications, microRNA interactions in viral infections, and the molecular mechanisms of viral replication. His work on Hepatitis C virus RNA capping with flavin adenine dinucleotide represents a major discovery in the field of virology. Additionally, his research extends to developmental biology, particularly in understanding transcription factor networks like TWIST1 in cell differentiation processes.

Analysis of his recent publications reveals a strong emphasis on RNA-virus interactions, particularly with flaviviruses including Hepatitis C, yellow fever, and tick-borne encephalitis viruses. His work on SARS-CoV-2 microRNA interactomes during the pandemic demonstrates his ability to pivot research toward emerging health threats. His publications in high-impact journals including Nature, Nature Communications, and Cell Reports highlight the significance of his contributions to the field.

Fossat has established productive collaborations with prominent researchers including Bukh, Scheel, and Ramirez, resulting in multiple high-impact publications. His work has received substantial attention, with several papers being highlighted in news outlets and social media platforms, indicating the broader impact of his research.
