Research Interests
My research interest in virology started with the numerous of mechanisms for exploiting normal host cell functions. This viral manipulation is associated with damage to the host cell which may be one of the major factors in the pathology and disease caused by viruses. I am interested in implementing research experiments based on virus-host interactions in influenza and dengue virus, to identify host factors that could regulate viral infection in susceptible cells.
In the present year, the appearance of new respiratory viruses as SARS-Cov2 has impacted radically the human world population. The interactions of the SARS-Cov2 viral proteins with cellular proteins are increasingly interesting to discover from new antivirals to understanding how this virus produces the pathogenesis in the COVID19 disease.
