Research Interests

My research training was in the areas of set theory and logic. In particular, I have published papers dealing with infinitary combinatorics and large cardinals. More recently I have become interested in modeling and applications of mathematics to biology. I have also been fortunate enough to work with members of the Institut für Medizinische Biometrie at the University of Tübingen.

Fall 2015 Classes

MATH 213:
R/Applied Calculus I

    The student will be introduced to the mathematics of linear systems and to the concepts, methods and applications of calculus. Mathematical questions arising in business and the life and social scienc
    es will be modeled and solved using these tools. Topics to be covered include linear systems of equations, matrix techniques, functions, limits, continuity, differentiation and integration. The approach will be graphical, numerical and analytic. Prerequisites: Precalculus or the equivalent. Not available to students with credit for MATH 221. Offered every semester

MATH 301:
Mathematical Logic

    The goal of the course will be to present the important concepts and theorems of mathematical logic and to explain their significance to mathematics. Specific results will include compactness, complet
    eness and incompleteness theorems, with applications including switching circuits and nonstandard analysis. Prerequisites: MATH 239. Offered fall, odd years.
