This is a temporary, full-time one (1) year position with the possibility of extension based on satisfactory performance, availability of work, and departmental funding.
Neuro Immuno Interface lab studies the interaction between sensory neurons, epithelial cells, and the immune system, and circadian rhythm roles in this interaction. Our lab has discovered cutaneous neurotransmitter and light receptors and their crucial function in skin sensation (itch and pain) , homeostasis and their relation to circadian rhythm. Using human primary keratinocytes, fibroblast culture, knock-out mice model with molecular and cellular techniques, we have characterized inter-cellular, cellular-matrix, skin cell, peripheral nerve fibers interaction and the receptor signaling pathways.
The incubant will conduct experiments and develop further the molecular biology related projects in the lab using epigenetic and transcriptomic analysis and molecular biochemical technique dissecting signaling pathway and transcriptional regulatory mechanism in the interaction between epithelial, immune, and nerve cells, and the effects of cytokines and neurotransmitters on epithelial circadian rhythms and the downstream effects of the circadian genes to the cellular DNA. Our lab mainly use human skin biopsies, primary keratinocyte, iPSC derived sensory neurons, and 2D and 3D model system as tools.
