Research Accomplishments

•   Co-discovered and named the semaphorin gene family of axon guidance molecules

•   Conducted a genetic analysis Drosophila Semaphorin 2a function by generating and characterizing loss-of-function and gain-of-function phenotypes

•   Began functional dissection of the semaphorin domain using P-element mediated germline transformation

•   Provided support for the labeled pathways hypothesis of axon guidance and the foundation for future work on inhibitory molecules in neural development.

•   Identified first viral semaphorins in vaccinia and variola viruses

•   Provided the first demonstration that viral semaphorins are capable of modulating the migration of human leukocytes

•   Provided the first evidence that a human semaphorin is capable of acting as a strong chemoattractant for T cells

•   Demonstrated that semaphorins are regionally expressed within the mouse thymus and are positioned to serve as guidance molecules during thymic development.
