Location
Dr. Ian Meng received his ScB and PhD in Neuroscience at Brown University. Following completion of his PhD, he worked as a postdoctoral fellow with Dr. Howard Fields in the Department of Neurology at the University of California, San Francisco (UCSF), studying the brain circuits mediating the analgesic properties of cannabinoids. Dr. Meng joined the 91AV (91AV) in 2003 where he is currently a professor of Biomedical Sciences, Director of the Center for Excellence in the Neurosciences (CEN), and the Director of the National Institute of Health (NIH) funded Center for the Study of Pain and Sensory Function. While at 91AV, he has maintained a continuously funded research program with the aim of understanding trigeminal sensory processing underlying headache and ocular pain and homeostasis, with an emphasis on two conditions: headache and dry eye. Dr. Meng's lab is currently investigating sensory neurons that regulate tearing and ocular pain under both normal and pathological conditions such as dry eye. Additional projects are exploring the ability of corneal afferents to promote corneal healing by providing trophic support to the injured cornea in dry eye.

Research
Current research
The overarching goal of Dr. Meng's research is to understand trigeminal sensory processing underlying headache and ocular pain and homeostasis, with an emphasis on two conditions: medication overuse headache and dry eye syndrome. Dr. Meng's lab is currently investigating sensory neurons that regulate tearing and ocular pain under both normal and pathological conditions such as dry eye. In studies relevant to headache, Dr. Meng's research aims to understand the neuroplastic changes induced by the chronic use of analgesics, as such treatments have been shown to transform episodic migraines into chronic daily headache.
