The main activity in the lab is to improve influenza vaccines. Current seasonal flu vaccines are poorly immunogenic and only work if the vaccine strains are closely matched against strains in circulation. The formulation has to be adjusted each season to cope with antigenic drift. We are exploring ways to increase the breadth and magnitude of the immune response to recombinant hemagglutinin using multivalent formulations, nanoparticle delivery vehicles, combination adjuvants (mixtures of TLR agonists) and emulsions. Techniques we use are serological profiling by protein microarrays, cytokine profiling in T cell recall assays, in vitro neutralization assays, and efficacy studies in vivo in the mouse model. Similar approaches are being used for the development broadly reactive vaccines against different ebola virus glycoproteins.
I am an immunologist with a special interest in vaccine development. I earned my Ph.D. at University College London (UCL), where, after a brief post-doc at Texas A&M Entomology Dept., I returned to develop HPV vaccines in the ICRF Human Tumour Immunology Group. I joined the faculty at King’s College London in 1991 where I taught immunology and continued research into HPV vaccines. I came to UCI on sabbatical in 2003, where I helped develop a proteome microarray platform using vaccinia virus as the model pathogen. My main focus at the moment is the development of non-reactogenic alternative vaccines against Q fever, methods for engendering broadly reactive vaccines using single-dose nanoparticle-based strategies, and molecular mechanisms of combination adjuvants.
