I am a Professor of Mathematics in the Department of Mathematical Sciences at 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, submanifolds, varieties, vector bundles, singularities, boundaries of open sets, pseudoholomorphic curves. I use the tools of topology, for example the Euler number, to describe the largescale 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.

I am not teaching in Summer 2024.
Since 2018 at Purdue University Fort Wayne, I've taught Calculus I and II (Math 165 and 166), Elementary Linear Algebra (Math 351), Differential Equations (Math 363), and Introduction to Complex Analysis (Math 525, offered as an online course). From Fall 1997 to Spring 2018 at IPFW, I taught Math 151: Algebra and Trigonometry, Math 154: Algebra & Trigonometry II, the Math 165166 sequence: firstyear calculus (formerly Math 163164), 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 also directed some independent graduate study courses in Math 598: Topics in Geometry, and Readings in Special Relativity, and the PhysicsBased Calculus workshop was offered for credit as Math 598 through the IPFW Division of Continuing Studies.

Under Construction Notice
The campus transition from IPFW to PFW came with a major web
site redesign from 2018 to 2022.
One part of the redesign was
that pages (including the department page) at the old
address ipfw.edu were mostly deleted and replaced by new
pages with URL pfw.edu.
Pages (including this page) with
URL users.ipfw.edu were not deleted but moved to the new
URL users.pfw.edu
I have previously had a web address at http://www.ipfw.edu/math/Coffman/ but this was obsolete in 2010 and deleted in 2013. Before that, I had a web page at uchicago.edu.
