About Me

I’m a neuroscientist researching genetic forms of Parkinson’s Disease at 23andMe. In my first postdoc, I studied multimodal hypersensitivity and pelvic pain. In graduate school, I studied volitional control of semantic processing, executive dysfunction in chronic-phase traumatic brain injury, and human reasoning. My undergraduate work utilized EEG to understand the neural correlates of analogical reasoning. In my spare time I enjoy reading, golfing, and the endless pursuit of new hobbies.
