Hai Qi Ph.D.

Main Research Fields

Using a variety of genetic, biochemical, cell biological, and imaging approaches, we ask following questions: (1) how cellular interactions critical for GC formation are molecularly orchestrated, (2) how qualitative and quantitative properties of such interactions are translated into cell fate decisions, (3) how lymphoid tissues and GC micro-domains are spatiotemporally patterned, (4) how such patterns facilitate productive while prevent unwanted immune activation at the same time, (5) how do memory B cells and long-lived plasma cells develop from GC and persist, and (6) how the central nervous system regulates these processes via physical neural circuits.
