I am a developer of open-source scientific software, and a scientist trained in acoustic phonetics, speech perception, and auditory neuroscience. My interest broadly centers on the perception and representation of speech sounds. I am also a certified Software Carpentry instructor.
Current position: Research Scientist at the University of Washington’s Institute for Learning & Brain Sciences, where I lead the development of MNE-Python neuroscience analysis software, and occasionally analyze infant and adult magnetoencephalography (MEG) data.
Structured bibliographic information for my research products is available in this BibTeX file.
