Mariano A. Garcia-Blanco was born in Puerto Rico, went to Harvard College for his undergraduate education, and received his MD, and PhD in Molecular Biophysics and Biochemistry from Yale University. He completed a fellowship with Dr. Phillip Sharp at the Massachusetts Institute of Technology. In addition to his appointment at Duke-NUS, Dr. Garcia-Blanco was a faculty member at Duke University (1990-2014), where he served as the inaugural Charles D. Watts Professor of Molecular Genetics and Microbiology, Professor of Medicine, and Director of the Center for RNA Biology. Since 2014 he is Professor and Chair of the Department of Biochemistry and Molecular Biology, and the Mildred Hajek Vacek and John Roman Vacek Distinguished Chair in Honor of President Truman G. Blocker, Jr. at the University of Texas Medical Branch.

Dr. Garcia-Blanco has made seminal discoveries to RNA biology and virology.  His studies on mRNA splicing have shed light on the mechanisms of splicing regulation, disease-causing splicing dis-regulation and a new type of RNA therapy.  Recently, he has focused his expertise on pathogenic RNA viruses and on RNA-centric mechanisms of immunity.  The RNA viruses he studies cause dengue, yellow fever and Zika, which threaten global public health.  His studies in immunity have centered on the role of RNA binding proteins on innate immunity, inflammation and autoimmunity.  He has published over 170 articles, reviews and chapters, and has been continuously funded by NIH (USA) since 1991. 

Dr. Garcia-Blanco was a Sackler Foundation Scholar, was elected to the Association of American Physicians (2011), fellow of the AAAS (2011), and fellow of the American Academy of Microbiology (2013). He has served in editorial boards and NIH panels, including the National Advisory Council for NIGMS, and the Council of Scientific Advisers of the International Centre Genetic Engineering and Biotechnology.

Flaviviruses are a major health problem in the tropics and represent an emerging danger to global health. This threat was loudly announced by the North American West Nile virus epidemic and the recent Zika virus pandemic.  Comparatively little is known about the molecular biology of these viruses, and the Garcia-Blanco laboratory is identifying host factors, both insect and human, that impact on the infection with pathogenic flaviviruses using en masse approaches.  Some of these factors, dependency factors, are required for efficient viral replication, while others, restriction factors, are components limit infectivity and are part of the host innate defense against viral pathogens. Given that flaviviruses live in an RNA world, never using DNA as genetic material, many of the newly identified host factors are RNA binding proteins.
