My work deals with finance, housing, and mortgage markets. I use applied statistical techniques on extremely large datasets to research and analyze policy issues at national, state, and local levels.
My site's two most frequently visited webpages are on LaTeX and Stata. The popularity of those pages is driven by two specialized videos that have drawn over 150K hits on my geeky YouTube channel. I made the videos a while back for my students while teaching but I never envisioned viewers and classes using them around the world. Out of curiosity and encouraged by cheap shipping, I have written a few product reviews on Amazon (my profile teeters around the top 5000 ranking). I remain intrigued by how technology and social media can translate small personal actions into larger social impacts.
