I generate mouse models to test HIV-1 vaccine candidates.  The goal of HIV-1 vaccine development is to design immunization methods that can elicit broadly neutralizing antibodies against diverse viral strains.  Our mouse models express precursors of broadly neutralizing antibodies. Immunization of these mouse models can evaluate the ability of the vaccine candidate to mature the precursor antibody into broadly neutralizing antibodies.

I work as a postdoctoral researcher, doing bioinformatic analysis, biostatistics testing and modeling for V(D)J recombination, somatic hypermutation and class switching recombination during B cell development, mainly based on high-throughput genome-wide translocation sequencing (HTGTS) and repertoire sequencing data.

Postdoctoral Fellows

My research is focused on elucidating the mechanism of chromatin loop extrusion-mediated class switch recombination.

Graduate Students

PhD student in Biological and Biomedical Sciences (BBS), Harvard University. 

I am interested in identifying mechanisms in brain neural progenitor cells that contribute to recurrent DNA breaks in a set of genes implicated in neuropsychiatric diseases and cancer.
