A father, a mathematician, and a fighter for working families
First as a mathematics professor, and now as a legislator, Daniel Biss has always tackled the hardest problems.
While teaching, Daniel’s desire to confront our state’s most critical problems compelled him to get more involved in his local community — first as an organizer, and later as a candidate.
Daniel has taken on the machine throughout his career, and knows how to win. His focus is on long-term, creative solutions for Illinois middle-class families, and fighting for those whose voices are typically ignored.
Daniel currently represents the 9th District in the Illinois State Senate
and previously served one term in the Illinois House representing the 17th District. He’s spent his time as a legislator expanding access, equity and care for all Illinoisians, fighting for financial security for families, and protecting our environment.
Daniel has taken the initiative to raise and make progress on issues significant to the future of Illinois that would have otherwise gone unaddressed, like helping giving retirement security to millions of Illinois workers and addressing the fast-evolving problem of technology and privacy. He combines the discipline and pragmatism of a math professor with the tenacity of an organizer in everything he does.
Daniel grew up in Bloomington, Indiana, and moved to Chicago after completing his Bachelor’s degree at Harvard University and his Ph.D. in mathematics at the Massachusetts Institute of Technology. At the age of 25, he joined the University of Chicago’s mathematics faculty.
His wife, Karin, is a former Peace Corps volunteer who recently completed her doctorate in history at Northwestern University. They live in Evanston with their two children, Elliot and Theodore.
