The laboratory focuses on using bioinformatic, optical, and molecular genetic methods to study the mechanisms leading to peripheral neuron cell type diversity. We have a particular interest in populations of peripheral neurons that detect distinct noxious stimuli. The primary efforts of the lab are to (1) understand the signaling pathways that allow for peripheral neuron populations to encode or react to noxious stimuli and (2) mechanistically understand how these populations can lead to or are altered by pathological pain states. We hope to take lessons learned to inspire the identification of new molecular targets for generating novel pharmacological therapeutics for pain-related pathologies.
