Stephanie Alexander earned her doctorate in 1967 at University of Illinois at Urbana Champaign and is now a professor in the same department. She is a geometer specializing in metric spaces, Alexandrov geometry, Riemannian geometry, Lorentz geometry and applications of geometry to robotics. After establishing herself as a major figure in the geometric community, she began a long term highly successful collaboration in 1987 with her doctoral advisor Richard Bishop, which has produced 21 papers and counting. She has had six doctoral students, one of whom is already a famous geometer, currently has three doctoral students, and regularly coauthors with young mathematicians including her prior students.
