Beau Sievers

Cognitive and social neuroscience research

I am a research scientist in the Stanford Social Neuroscience Laboratory advised by Professor Jamil Zaki and a research associate in Psychology at Harvard University advised by Professors Joshua Greene and Leslie Valiant. I completed my PhD in Cognitive Neuroscience at Dartmouth College, advised by Professor Thalia Wheatley.

I am also a composer and performer on percussion and electronics, and was a founding organizer of Indexical.

Bouncing Ball

Bouncing Ball is open source software for comparing the dynamics of music and movement as described in Sievers, B., Polansky, L., Casey, M., & Wheatley, T. (2013). Music and movement share a dynamic structure that supports universal expressions of emotion. Proceedings of the National Academy of Sciences, 110(1), 70-75.

Morphological Metrics

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

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 consonance).
