Daniel Heath, also known as “Deej,” earned a B.A. in mathematics at St. Olaf College, where he was one of the first few math majors to study in the Budapest Semesters in Mathematics program. He went on to earn an M.A. and Ph.D. in mathematics at the University of California at Davis, and continued to postgraduate study in geometric topology at Nara Women’s University. His scholarly interests include low-dimensional topology (knot theory) and geometry.
