William "Connor" Castonguay joined the Brennan Lab in the winter of 2023 as a research technician. He specializes in mouse behavior models and their application towards better understanding various forms of headache such as migraine and post traumatic headache. By measuring numerous headache criteria in mice, including but not limited to photophobia, tactile hypersensitivity, and anxiety, we hope to better understand the underlying mechanisms and potential treatments of headache to help alleviate the burden headache causes for so many on a day-to-day basis.
