Daniel Biss received his PhD in mathematics at MIT in 2002, then was an Assistant Professor at the University of Chicago until 2008. He won the 1999 Morgan Prize for outstanding research as an undergraduate. However, in 2007, a serious flaw was discovered that destroyed the main results of papers he had published in the Annals of Mathematics and in Advances. He is now a State Senator in Illinois. I have no idea how much his mathematical background influences his decisions, but in this position, he has worked on legislation touching on mathematical topics, such as legislation to "allow for automatic voter registration," to "elect a number of statewide offices by ranked-choice ballot," and on healthcare, among other things.
