    Cynthia CurtisCindy Curtis

    Chair and Professor, Ph.D., Yale University
    Office: SCP 233, x-2026
    Email: ccurtis

    Office Hours:

    Mondays from 11:30 am to 12:20 pm

    Wednesdays from 9:00 am to 10:50 am and by appointment.

    Please email Dr. Curtis to schedule.

    email: mathstat@

    Research Interests – Professor Curtis studies three-dimensional spaces (such as our universe) and knots. Interestingly, all three-dimensional spaces can be built from knots, so understanding knots and understanding 3-dimensional spaces are closely related. Most of her work involves trying to understand how we can recognize when two spaces or two knots are different from one another. (Imagine two different massively tangled shoe laces and ask yourself how you would know if they are tangled in exactly the same way!)

    Teaching Interests – Dr. Curtis has taught a variety of courses in the department, especially multivariable calculus; linear algebra; various upper level courses in geometry and topology; and the math capstone course.

    Undergraduate Research Interests – Dr. Curtis has supervised numerous students in undergraduate research projects in topology, most often on projects involving knots.

Previously, he has worked in combinatorics and applied algebraic geometry (in phylogenetics to predict evolutionary trees in biology).

    Teaching Interests – Professor Hagedorn primarily teaches courses in linear algebra, abstract algebra and number theory, but also has interests in the teaching of calculus and the use of technology in mathematics instruction. He has taught courses in cryptography, geometry, the mathematics of voting and choice, and the culture, politics and science of food (as part of the TCNJ’s FSP program). He has also mentored many independent study, independent research, and capstone projects on a diverse range of subjects including cryptography, the rank of elliptic curves, the circumference of an ellipse, Riemann surfaces, and moduli spaces in physics.

    Judit KardosJudit Kardos

    Associate Professor, Ph.D., University of Missouri – Kansas City
    Office: SCP 241, x-2241
    Email: kardosj

    Research Interests – My research interests are focused on two areas: Real Analysis and the teaching of Real Analysis. In my research on Analysis, I have been studying Space Filling Curves (SFC) for the past few years.  A space filling curve is a continuous function mapping the interval $[0,1]$ onto  the unit square. Space filling curves, which first seemed like a mysterious aberration, signaling how far mathematics had strayed from the world of everyday experience, provide a perfect tool today for computer scientists who want to linearly order a multidimensional data set. In particular, Space Filling Curves provided an essential tool for decoding the human genome in bioinformatics.

    Teaching Interests – I am teaching all my courses as discovery-based, problem-solving courses using elements of IBL and the Pósa-method, which is named after my teacher Lajos Pósa. Based on research by Bjork, I teach my classes using a low stake continuous testing environment with lots of online practice quizzes. I am very interested in using novel geometric approaches in teaching Real Analysis. My most recent paper on Constructing Continuous Functions describes a novel geometric construction method for the construction of continuous functions.

    John NardiniJohn Nardini

    Assistant Professor, Ph.D., University of Colorado, Boulder
    Office: SCP 239
    Email: nardinij

    Research Interests – Dr. Nardini develops mathematical tools and models to answer biological questions involving wound healing, cancer progression, and medicine.  He is particularly interested in the development of novel methods that inform how we can best use data to inform the mathematical modeling process. Some of his favorite tools and methods include agent-based modeling, differential equations, equation learning algorithms, and topological data analysis.

    Teaching Interests – Dr. Nardini uses both metacognitive and active learning-based pedagogical methods in the classroom. In metacognition, students reflect on their learning process over time and better understand themselves. With active-based learning, students spend time actively engaging with material during class. Dr. Nardini has successfully used these methods in pre-calculus, Calculus, and Introductory Proofs courses.
