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.

My Classes

Math 262:
R/Applied Statistics

    An introduction to statistics with emphasis on applications. Topics include the description of data with numerical summaries and graphs, the production of data through sampling and experimental design, techniques of making inferences from data such as confidence intervals and hypothesis tests for both categorical and quantitative data. The course includes an introduction to computer analysis of data with a statistical computing package. (Those who have completed MATH 360 may not enroll in this course for credit, and no student may reveive credit for more than one 200-level statisticcs course, including credit for more than one of the following courses: BIOL 250, ECON 205, GEOG 278, MATH 242, MATH 262, PLSC 251, PSYC 250, and SOCL 211.) Offered every semester

Math 340:
Modeling Biological Systems

    Computer and mathematical models are increasingly important tools used to understand complex biological systems. Under the guidance of biology and mathematics professors, students will work both individually and in groups to develop, analyze and present models of various biological systems ranging from disease models and diffusion processes to ecosystem dynamics. The course involves two hours of lectures and a two hour computer-based laboratory. (Cross listed with BIOL 340.) Prerequisites: MATH 222 and at least one of the following: BIOL 203, BIOL 222, MATH 223 or permission of the instructor. Offered spring, even years and when demand is sufficient

Math 383:
Biomathematics Seminar

    A discussion course dealing with selected areas of biomathematics based on current literature and/or guest speakers. Prerequisites: Permission of the instructor. May be taken multiple times for credit with the permission of instructor. Offered spring, even years
