My lab studies the sensory neurobiology of pain with a focus on calcium-mediated signaling. Transient receptor potential (TRP) ion channels have been implicated in the pathophysiology of migraine, a neurological disorder with incapacitating episodic headaches. Ca2+-permeable TRP ion channels have been shown to function in many diverse physiological processes including inflammation and pain. TRP ion channels are expressed and function in trigeminal (TG) sensory neurons, in keratinocytes (KCs) and in mast cells. My research agenda include how TRP ion channels in skin keratinocytes and mast cells regulate the secretion of inflammatory mediators onto nerve cells resulting in inflammation and pain. The underappreciated cross-talk between TG neurons and innervated non-neural cells, skin KCs and meningeal mast cells will benefit from increased scrutiny.

To better understand chronic, pathological pain at the organismal level, we use genetic rodent models. Our approaches include behavioral, structural, and molecular studies and advanced imaging. Migraine is the most common neurological disorder and affects >20% of women and 3-5% of men. For a significant number of migraineurs the onset occurs during their teenage years, and they continue to suffer thereafter, so that migraine’s impact affects migraineurs during their peak productive years and during a decisive period of their lives.

Widespread therapeutic use of onabotulinum toxin-A (botox) has exerted a powerful impact on migraine. However, botox’s mechanism of action on the trigeminal sensory system remains elusive.  In relation to migraine we study how Botox work in the regulation of TRP channels in trigeminal sensory neurons to prevent/treat migraine.
