Scientific research on structural aspects of the replication, transcription and immune response evasion in filoviruses (Ebola and Marburg viruses), SARS-related coronaviruses and other highly pathogenic RNA viruses. OSINT analysis on biological threats related to highly pathogenic RNA viruses.- Structural characterization of viral proteins and virus macromolecular complexes by means of transmission electron microscopy (cryo-EM and negative stain) and X-ray crystallography.- Biophysical characterization of recombinant viral proteins expressed in and purified from heterologous systems. - In vitro biochemical assays for the characterization of protein:protein and RNA:protein interactions.- Analysis and consulting on topics related to the emergence of highly pathogenic RNA viruses as global health threats, as well as on biological warfare, bioterrorism, biodefense and counterproliferation of bioweapons that involve dual-use technologies on highly pathogenic RNA viruses.
