Nicholas Koberstein joined the NCSSM mathematics department in August of 2018. Teaching AP Statistics and AP Calculus BC, he focuses on creating a safe and welcoming learning environment that puts students at the center of their education. If you walk into one of his classes, you will often find groups of students working together to solve problems or students presenting their work to the class and answering questions their classmates pose.  He has also co-taught the Research in Mathematics Mini-Term course and co-presented about the mentoring experience at the Teaching Contemporary Mathematics conference, National Council of Teachers of Mathematics (NCTM) regional conference, and National Consortium of Secondary STEM Schools (NCSSS) Professional Conference.

Todd Lee is a professor of mathematics at Elon University, NC. While having teaching experiences with most math courses offered at Elon over the last 25 years, Todd’s teaching experience includes spending some of his first summers chairing the Governor’s School-West program in mathematics, to spending the last three summers co-leading NCSSM’s summer math research program. Though his graduate work at Texas Tech was in PDE’s and complex analysis, his mathematical scholarship goes in whatever direction his undergraduate research students’ interests take them. Todd’ teaching scholarship focuses on reconstructing traditional courses to include inquiry-based and self-paced hybrid pedagogies, teaching cognitive science as foundational to first-year students, orchestrating student research experiences for a broad range of students, as well as ramping up expectations for growth in the use of industry-level technologies.
