Ooi Yaw Shin

Assistant Professor


Yaw Shin is an Assistant Professor in the Emerging Infectious Diseases (EID) program at Duke-NUS Medical School. He received his doctorate from Albert Einstein College of Medicine (Mentor: Margaret Kielian), New York, and later pursued his postdoctoral training at Stanford University (Mentor: Jan Carette), California. He has a long-established interest in discovering cellular factors (host dependency factors and restrictions factors) that determine susceptibility and permissivity to virus infections. Host dependency factors are keys hijacked by viruses to penetrate cellular barriers and rewire host cells for promoting viral protein translation, genome replication, assembly, exit, and spread. In contrast, viruses must evade antiviral innate immunity to avoid tolls during the infection process, especially by antagonizing host restriction factors. Currently, his team's focus is centered on mosquito-borne RNA viruses and human respiratory RNA viruses – all pose serious threats to global public health.

Studying one host gene is good; carry along all genes is even better.’ – Jan Carette

Functional genomic approaches such as genome-scale CRISPR editing, Haploid genetic screen, and genome-wide RNAi have continuously driven the discovery of new knowledge about many emerging and re-merging viruses. We leverage the awesome power of functional genomics to unbiasedly uncover host factors essential for infection and pathogenesis of clinically significant RNA viruses. Our discovery will shed light on the underlying molecular mechanisms of viral infections and diseases, and we hope to provide new knowledge for improving vaccine designs and development and innovating antiviral strategies.
