Research Interests:
Research: My main area of interest is computability. In particular, my work has been in computability in topology and in analysis where the objects of interest have been those that are computable, those that are incomputable, and those that are computably incomputable.
Research with graduate students: I am interested in working with students who are directed, or who become directed, in pursuing a Ph.D. focusing on aspects of computability in mathematics.
Research with undergraduate students: I am interested in helping students find a specific theorem in a junior or senior level mathematics course, and researching it. This research could include the history of, the variety of the proofs for, and the applications of that theorem. Students would be expected to consult various textbooks and accessible journals to gather and examine different proofs or applications, and to write a paper on their findings. I am also interested in helping students develop a computer animation/study of a theorem and its proof, or of a phenomenon in dynamical systems or cellular automata (or similar areas). Students would write a paper and a program demonstrating thoughtful understanding of the theorem, its proof, and its computer illustration.
