Dr. Garcia-Sastre is Professor in the Department of Microbiology and Director of the Global Health & Emerging Pathogens Institute at Mount Sinai School of Medicine in New York. He is also Principal Investigator for the Center for Research on Influenza Pathogenesis (CRIP), one of five NIAID Centers of Excellence for Influenza Research and Surveillance (CEIRS). Together with Charlie Rice, he is the leader of the basic research component on Viral Therapeutics and Pathogenesis of the North East Biodefense Center proposal, which was funded by NIAID and involves the collaboration of more than 20 academic institutions in New York, Connecticut and New Jersey.
For the past 20 years, his research interest has been focused on the molecular biology of influenza viruses and several other negative strand RNA viruses. During his postdoctoral training in the early 1990s, he developed for the first time, novel strategies for expression of foreign antigens by a negative strand RNA virus, influenza virus. He has made major contributions to the influenza virus field, including 1) the development of reverse genetics techniques allowing the generation of recombinant influenza viruses from plasmid DNA (studies in collaboration with Dr. Palese); 2) the generation and evaluation of influenza virus vectors as potential vaccine candidates against different infectious diseases, including malaria and AIDS; 3) the identification of the biological role of the non structural protein NS1 of influenza virus during infection: the inhibition of the type I interferon (IFN) system; and 4) the reconstruction and characterization of the extinct pandemic influenza virus of 1918. His studies provided the first description and molecular analysis of a viral-encoded IFN antagonist among negative strand RNA viruses. These studies led to the generation of attenuated influenza viruses containing defined mutations in their IFN antagonist protein that might prove to be optimal live vaccines against influenza. His research has resulted in more than 100 scientific publications and reviews. He was among the first members of the Vaccine Study Section of the NIH.
In addition, he is an editor for Journal of Experimental Medicine and PLoS Pathogens and a member of the Editorial Board of Journal of Virology, Virology, Journal of General Virology and Virus Research. He has been a co-organizer of the international course on Viral Vectors (2001), held in Heidelberg, Germany, sponsored by Federation of European Biochemical Societies (FEBS), and of the first Research Conference on Orthomyxoviruses in 2001, held in Teixel, The Netherlands, sponsored by the European Scientific Working Group on Influenza(ESWI).

The Garcia-Sastre Laboratory is focused on exploring virus-host interactions with emphasis on virus regulation of innate and adaptive immune responses. The outcome of these interactions not only determines disease severity but also influences the development of protective immunity resulting from viral infection and/or vaccination. The team has developed several techniques (reverse genetics), which allow for the genetic manipulation of the genomes of several virus families including influenza virus and Newcastle disease virus. Other viruses being studied include Dengue virus, West Nile virus, and Crimean-Congo hemorrhagic fever virus. These techniques are currently being used in several research areas including: i) characterization of virus-encoded virulence factors, ii) identification of virus-encoded antagonists of the interferon system, iii) virus replication and gene expression, iv) immune regulation of influenza replication, and v) vaccine development.
Reverse genetics are also being utilized to generate virus vectors based on influenza virus and Newcastle disease virus. These viruses are effective inducers of humoral and cellular immune responses. Live attenuated influenza virus vaccines are being generated by genetic modification of the influenza virus-encoded interferon antagonist that was originally identified by the laboratory. Also, recombinant viruses can be produced that express protective antigens of other pathogens for which no safe attenuated vaccine strains are available.
