My research interests are in mathematical linguistics, particularly in the subregularity of syntax and morphology. My current work is focused on assessing the complexity of morphological reduplication. I am happily advised by Thomas Graf.

I am from Indianapolis. In my speech, I proudly sport the pin-pen merger, the cot-caught merger, needs washed, and punctual whenever!
