BIOGRAPHY AND RESEARCH INTERESTS

My research focuses on the formation of the primitive heart tube. Specifically, I am interested in factors controlling the migration of the precardiac mesoderm from bilateral positions to the embryonic midline. I am using two mutations, miles apart and two of hearts, to study this process. miles apart encodes the zebrafish orthologue of the mammalian G protein-coupled receptor S1P2 and seems to function with the, as of yet unidentified, two of hearts locus to regulate precardiac mesoderm migration.
