Research Interests

Research in the Rimer lab centers on the molecular and cellular mechanisms underlying the formation, maintenance and pathology of synapses, the connections between nerve cells and their targets.  Because of its simplicity and experimental accessibility we have used the vertebrate neuromuscular junction (NMJ) as our model system. The NMJ is the synapse between a motor neuron and a skeletal muscle fiber. We address these problems using state-of-the-art mouse molecular genetic techniques in combination with standard molecular, cellular, and immunological approaches.

I participate in graduate training as a member of the faculty in the Interdisciplinary Program in Neuroscience and the Medical Science PhD program in the College of Medicine.
