Instead of multiplying on the left or on the right, he’d rather be able to multiply on the top and bottom as well. He’s also branched out into 3 dimensions as well. He also does research in knot theory, subfactors, quantum groups, and category theory. He was a mentor at Mathcamp from 2006-2008 and the AC in 2009, and a visitor in 2010-2016. He cowrote the 2008 and 2010 Mathcamp puzzle hunts, and the 2006 and 2011 MIT mystery hunts. He likes extinct animals, and baby tapirs. Visit Noah's website.
