I trained as a specialist in Infectious Diseases and I have always been interested in the immunological control of persistent viral infections, particularly Hepatitis B (HBV).

During my research career, first in USA (The Scripps Research Institute) and then in Italy (University of Parma), I was the first to characterize hepatitis B virus (HBV)–specific human CD8 T cells in HBV infected patients (Proc. Natl. Acad. Sci. USA 1991 88: 10445), and to define the effect of HBV mutations in HBV-specific CTL function (Nature 1994 369: 407-J. Exp. Med. 1994 180: 933)

I moved to London (University College of London) in 1997, where I pioneered the use of HLA-tetramers in HBV infected subjects and used them to characterize the role of HBV-specific T cells in viral control and disease pathogenesis (J. Exp. Med. 2000, 191: 1269 ,J. Exp. Med, 2002 195: 1089; J. Virol, 2004, 78;5707)

In 2006 I moved to Singapore, motivated by the opportunity to build on our understanding of HBV infection, a worldwide serious health problem that is over-represented in Asia and I became Director of Infection and Immunity Program at the Singapore Institute for Clinical Sciences (A*STAR) until 2013, after which I joined as a Professor in the Emerging Infectious Disease Programme at Duke-NUS Graduate Medical School in the same year.

In my laboratory we characterized the impact of Asian HLA- class I profile and HBV genotypes on on HBV immunopathogenesis (J. Virol. 2008 82: 10986, Gastroenterology 2012, 43 :637; J Clin Invest. 2013 123(9):3766). Our current research focuses on the development of new immunological based therapies (TCR-redirected T cells, HLA-peptide specific antibodies) for the treatment of HBV and Hepatocellular carcinoma (HCC), and the characterization of human intra-sinusoidal hepatic immune system.
