I am working on
MathPapa,
a free algebra calculator that uses interactive diagrams and step-by-step explanations to make middle-school math more intuitive.
My MathPapa Tumblr focuses on middle-school math education and technology.
I made a brief tutorial site on adding fractions.
I will be posting interactive algebra lessons at Variable X.

Bio
I was a computer science PhD student at Stanford, graduating Autumn 2012. My
advisor was Jennifer
Widom. My main research project was Panda, a system that uses data provenance to help data analysts debug their workflows.
