    Instructor Schedule

    Research InterestsDr. Cunningham’s research focuses on both pre-service and in-service mathematics teachers. Of special interest are topics from the secondary curriculum that pose the greatest challenge for teachers to teach and students to learn. His research in mathematics education has also examined technology in support of instruction.

    Teaching InterestsDr. Cunningham teaches Calculus, Linear Algebra, Methods for Teaching Mathematics, and the Collaborative Capstone for Professional Inquiry course. In addition, he supervises student teachers.  His lively interest in teaching and research has prompted him to involve undergraduate students in conducting, presenting, and publishing mathematics education research.


    Cynthia Curtis

    Professor, Ph.D., Yale University
    Office: SCP 208, x-2026
    Email: ccurtis@tcnj.edu

    Instructor Schedule
    On sabbatical.

    Research InterestsProfessor 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 InterestsMost frequently, I teach multivariable calculus and various upper level courses in geometry and topology. I have also occasionally taught courses in algebra and number theory, and one semester I taught an FSP on the shape of the universe. Finally, I very much enjoy supervising undergraduate research projects, most commonly in knot theory

    Office: SCP 209, x-2241
    Email: kardosj@tcnj.edu

    Instructor Schedule
    Research Interests -  I am interested in problems in Real Analysis that provide insight into the highly unintuitive nature of the actually infinite. I worked on problems related to Cantor-type sets on the real line, finding Hausdorff dimensions and measures of such sets. I am also interested in understanding the changes in the wider historical and philosophical views of the infinite that eventually lead to the legitimization of the use of the actually infinite in mathematics.

    Teaching InterestsI have implemented new technology in our introductory courses in Statistics and Linear Algebra. I was in charge of recreating our course in History of mathematics with a broader philosophical perspective to satisfy the World Views of Knowing Liberal learning requirement. I have guided several capstone projects in the areas of Number theory and Real analysis.  I am teaching all my courses as discovery based, problem solving courses in the Hungarian tradition. Courses offered regularly include Calculus and courses in Real analysis including upper level seminars and Independent Research.

    Office: SCP 205, x-2189
    Email: ochsm@tcnj.edu

    Instructor Schedule

    Research Interests – Dr. Ochs focuses on the intersection of statistical learning and biological systems, with a primary interest in inference on molecular activity in cancer. He is presently developing computational statistical methods for refining our understanding of cell signaling. Methodologies rely on outlier statistics computed from nonparametric distributions and Bayesian Markov chain Monte Carlo simulation with priors developed from known biology.

    Teaching Interests – Dr. Ochs teaches introductory and upper level statistics courses. His research and teaching intersect most strongly in STA307 Data Mining and STA370 Bayesian and Computational Statistics (to be introduced in Spring 2015). Dr. Ochs focuses all courses on developing an ability to choose statistical approaches and techniques for real world problems, as computers can now easily handle even the most arduous statistical calculations but cannot decide what analysis fits the data.
