Research interests: My work is focused on understanding the molecular mechanisms underlying left-right identities in the dorsal diencephalon of zebrafish.

The zebrafish dorsal diencephalon is composed of the medially positioned pineal organ, the left-sided parapineal nucleus and the bilateral habenulae. Moreover, the habenular nuclei are comprised of multiple subnuclei and display conspicuous left-right asymmetries in cytoarchitecture, neurotransmitter expression and connectivity.

Establishment of asymmetries in the dorsal diencephalon is thought to occur concordantly and in a stepwise mechanism not fully understood. It is known that parapineal migration is crucial to the development of left habenula (LHb) identity but the molecular and cellular nature of parapineal-LHb progenitors communication remains unknown.

In order to understand how left and right identities arise and are maintained within habenular nuclei, a forward genetic screen was performed to identify phenotypes in which a parapineal is present but the elaboration of habenular asymmetry is disturbed. I am currently studying two novel mutants - rorschach and narcissus - in which the body asymmetry is normal but the epithalamus displays left-sided isomerism. These novel asymmetry mutants can be used as a valuable tool to understand the decoupling of parapineal migration and habenular asymmetry and to further our understanding of the development pathway of the habenulae nuclei.
