Get a Good Handle on Statistics and Math with Patient, Encouraging PhD

I have a PhD in Cognitive Psychology from the University of Pennsylvania, where I researched statistical probability models of medical diagnosis. After that I worked for a small research and development company, leading projects focused on preventive health and automated cancer diagnosis. I've always felt comfortable with math and enjoy uncovering the ways that formulas and data interact. I especially appreciate statistics and biostatistics, which can give us a glimpse into how nature work...
