Faculty & Staff

Sarah Bockting-Conrad
Associate Professor
DePaul University

Professor Bockting enjoys sharing her love for mathematics with students and is looking forward to her 1st year at MathPath! She particularly enjoys working with students on problems in graph theory and combinatorics, though she is often wearing her "algebraist hat" when doing her own research. In fact, during summer 2023, Professor Bockting and colleague mentored a group of nine undergraduate students on research projects in graph coloring and had an absolute blast! Professor Bockting is the 2022 recipient of the DePaul University Excellence in Teaching Award and is involved in various efforts to make her communities into more inclusive and equitable places. When not doing math, Professor Bockting enjoys baking, running, and doing outdoorsy things with her family such as going camping and hiking.

After finishing their PhD in the Summer of 2020 at the University of Delaware, Kris Hollingsworth spent two years teaching a rigorous, proof-based Calculus sequence for advanced high-school students at the University of Minnesota's Talented Youth Mathematics Program (UMTYMP) in Minneapolis. They are now a tenure-track Assistant Professor at the University of Minnesota, Mankato in the Department of Mathematics and Statistics. Kris lives in Southwestern Minnesota with their partner and spends most of their free time being taken on long walks by Gemma (their Aussie Beagledor), shoveling excessive amounts of snow and ice in the frigid north, and hoping someday to have enough time to actually unpack all the boxes they dragged from Delaware to Minnesota and hasn't opened in the past four years. This will be their 2nd summer at MathPath, and they are excited to return!

Silas Johnson

Valerie Peterson
Associate Professor
University of Portland

Having taught math for 15 years at the University of Portland, Dr. Valerie Peterson is delighted to join MathPath for the 1st time this year. Her early research in algebraic topology and metric geometry (with just a splash of robotics) has given way to studying institutional change, peer observation, and inclusive, student-centered pedagogical practices. Her favorite moments in math are the collaborative ones, working with students who are learning to think about mathematics in new ways, and supporting other college faculty who are trying to approach their teaching in new ways. Suffering from an abundance of hobbies, Valerie enjoys experiments with yarn, fabric, and plants, loves transforming simple ingredients into delicious meals, and dreams of someday uniting people on the dance floor with her electronic beats. She is the second-tallest member of her household of five in Portland, OR (which includes two relatively short cats).
