I’m a learning scientist, mathematics educator and design-based researcher in the Department of Education at Tufts University. My research interests are (1) designing and building computer-based toolkits for learners to express and test their ideas about math and science; and (2) finding out how students and teachers think and learn about complex, data-rich, and statistically nontrivial quantitative phenomena.

I am 2012-2013 Chair of the American Educational Research Association’s Special Interest Group in Advanced Technologies for Learning (SIG-ATL), and PI of a 3-year NSF funded project entitled SiMSAM: Bridging Student, Scientific, and Mathematical Models with Expressive Technologies with Brian Gravel to develop an integrated animation, simulation and data analysis tool for middle school science. I’m also part of The Poincare Institute, an NSF Math Science Partnership professional development program for middle school mathematics teachers across greater New England. I hold a PhD in Learning Sciences from Northwestern University, and Bachelors degrees in Mathematics and Education from the University of San Diego.
