Dr. Katie V. Johnson earned her B.S. in mathematics (with honors) from the College of William and Mary, and M.S. and Ph.D. in mathematics from the University of Nebraska-Lincoln.  Her research interests include combinatorics and graph theory, with a particular fondness for probabilistic arguments and clever algorithms.  She co-organizes a weekend event for middle-school girls called GEMS (Girls in Engineering, Math, and Science) that exposes girls to interesting STEM topics that they likely won’t see in their classes.  Dr. Johnson is also a co-PI on a large NSF Noyce grant that provides scholarships for STEM majors who agree to teach in local high-needs public schools after graduation.  As part of this grant, she runs the Learning Assistant program and the Summer Internship program.  Dr. Johnson has a one-year old son named Lucas, a loving husband Brian who is also a math professor, and a German short-haired pointer dog named Maggie.  She loves to bake and travels whenever she can!
