Research Description:

The mammalian central nervous system (CNS) is composed of thousands of different types of neurons. However, it remains to be determined what cellular and molecular mechanisms are involved in the generation of this neuronal diversity. Fundamental questions of my research are: (1) when or where is the fate of a cell specified? Is it during its progenitor stage, or is it after it has become post-mitotic, or both? (2) What genes or transcription factors are involved in the specification of certain neuronal type? And (3) can we manipulate or change the fate of cells in vivo using genetic techniques?

To answer these questions, my research focuses on the thalamus, a structure in the diencephalon that is important for processing visual, auditory, and somatosensory inputs from the periphery as well as secondary inputs from other brain regions including the cortex. Unlike other brain structures, the thalamus is uniquely organized into clusters of cell aggregates called nuclei, with each nucleus composing of its own neuronal type. How these different neuronal types arise from a single layer of progenitor cells to form multiple nuclei is not understood. The goal of my thesis is to research the genetic cascade involved in cell fate specification and nuclei formation in the developing thalamus in the mouse.

With the degree of neuronal diversity within the thalamus, I believe deciphering this genetic cascade will provide critical insights into how the entire CNS develops.
