Last update: Aug. 25, 2014.
I am a Professor of Mathematics in the Department of Mathematical Sciences at Indiana University - Purdue University Fort Wayne.
I am interested in geometry of all kinds. Currently, I am studying the geometric properties of real objects inside complex objects: vector spaces, matrices, immersed manifolds, varieties, vector bundles, singularities, boundaries of open sets, pseudoholomorphic curves. I use the tools of topology, for example the Euler number, to describe the large-scale structure of the objects, and methods of several complex variables, including power series and partial differential equations, to describe the local geometry. I'm also interested in classical projective geometry, abstract algebra, and physics, and I often use the computer for symbolic manipulation and graphics.
For the Fall 2014 semester, I am teaching two sections of Differential Equations (Math 363). My office hours are 4:30-5:30 on Tuesdays/Thursdays. I will have a one-semester sabbatical during Spring 2015.
Since Fall 1997, I have taught Math 151: Algebra and Trigonometry, Math 154: Algebra & Trigonometry II, the Math 165-166 sequence: first-year calculus (formerly Math 163-164), Math 175: Introductory Discrete Mathematics, Math 261: Multivariate Calculus, Math 262: Linear Algebra and Differential Equations, Math 263: Multivariate and Vector Calculus, Math 351: Elementary Linear Algebra, Math 363: Differential Equations, Math 453: Algebra I, MA 511: Linear Algebra with Applications, Math 525: Introduction to Complex Analysis, Math 553: Introduction to Abstract Algebra, Math 554: Linear Algebra, Math 560: Fundamental Concepts of Geometry, and Math 571: Elementary Topology. I have also directed some independent graduate study courses in Math 598: Topics in Geometry, and Readings in Special Relativity, and the Physics-Based Calculus workshop has been offered for credit as Math 598 through the Division of Continuing Studies.
