In the Siegrist Lab, we are working to understand how the immense number of molecularly and functionally distinct neuron types are produced during development and importantly, how natural environments impact generation of neuron number and diversity in animals living in the real world. Research in the Siegrist lab is focused on the following fundamental themes.
1) Nutrient-dependent control of neural stem cells in their niche
2) Intrinsic genetic programs and temporal identity factors that control neural stem cell proliferation timing and neuronal diversity
3) Neural circuits involved in nutrient sensing and brain growth control
