I study how people represent ideas so they can share them.
I am a postdoctoral researcher in the Department of Psychology at Harvard University advised by Professor Joshua Greene. I completed my PhD in Cognitive
Neuroscience at the Dartmouth Social Systems Lab advised by Professor Thalia Wheatley. My research
focuses on how ideas are represented in the mind, made sensible in the world, and then internalized by other
minds. This sharing of representations allows groups of agents to act in concert, producing mutually
supportive, coordinated behavior. I can be found on Twitter and
I am (very occasionally) writing a blog about my research.
I am a composer, and was a founding member of Indexical.
Please feel free to email me.

Morphological Metrics is a Ruby
implementation of metrics described in Larry
Polansky's article Morphological Metrics. Larry's work on Morphological Metrics is of interest
for anybody who wants to quantitatively compare contours; I came to it as a composer and continue to return
regularly as a scientist.
Ruby PCSet is a simple Ruby library for performing
musical pitch-class set theory operations. It has a few nice things which similar tools lack, including
evaluation of some properties described by Balzano (coherence, uniqueness) and Huron (aggregate dyadic
