courses I’ve taught

I love all of the mathematics I’ve ever learned, but the teaching I’ve done reflects mostly my mathematical interests: geometry, analysis, and topology.

at UPenn
  • MATH 103: Introduction to Calculus
    A first course in calculus (differentiation and integration), with a focus on interpretation and application of the computations.
  • MATH 104: Calculus part I
    Techniques of integration and the excellent question: What if you added like, infinitely numbers, man?
  • MATH 114: Calculus part II
    Multivariable calculus. Vectors, vector algebra, and vector functions. Functions of several variables, partial derivatives, gradients, directional derivatives, maxima and mimima. Multiple integration. Line and surface integrals, Green’s Theorem, Divergence Theorems, Stokes’ Theorem.
    This course shows the first inklings of differential geometry.
  • MATH 240: Calculus part III
    Solving systems of linear equations and the linear algebra that allows us to do it. In the second half of the course, we switch gears to apply the linear algebra to (linear) systems of ordinary differential equations.
  • MATH 241: Calculus part IV
    Theory and practice of solving partial differential equations, focusing on those motivated by the basic physics of waves and heat.
  • MATH 312: Linear Algebra
    A deeper dive into linear algebra than that in MATH 240. This is a course for Engineering students; in addition to the theory, about half the course is devoted to programming computations (via SAGEmath), which can handle them better and quicker than we can and allow us to focus on the applications of linear algebra to all sorts of stuff.
  • MATH 360:¬†Advanced Calculus
    Proving all of the familiar theorems of single-variable calculus.
  • MATH 600: Geometric¬†Analysis and Topology I
    The smooth manifold is the basic object of differential geometry. This course develops smooth manifolds, vector bundles, tensors, and exterior calculus. We get a few glimpses of the differential-geometric ways to measure topological quantities: Stokes’ and de Rham’s Theorems.
 at NCSU
  • MA 132: Computational Mathematics for Life and Management Sciences
    This is a one-hour course in using Excel and Maple to do the “grunt work”, so we can focus on applying calculus to real-world phenomena that range from a market becoming saturated to bacterial growth.
    Starting Fall 2018, this course is offered online.
  • MA 141: Calculus for Scientists and Engineers, I
    Functions, graphs, limits, derivatives, rules of differentiation, definite integrals, fundamental theorem of calculus, applications of derivatives and integrals.
  • MA 225: Foundations of Advanced Mathematics
    An introduction to proofs for mathematics majors (and anyone else who wants to be introduced to proofs). This course is so much fun to teach!
    A set of notes (the core of which was produced with the assistance of the NCSU Libraries’ Alt-Textbook Project) is here. (As of Fall 2018, the WordPressification of these notes is ongoing.)
  • MA 242: Calculus for Scientists and Engineers, III
    Same syllabus as MATH 114
  • MA 408: Foundations of Euclidean Geometry
    An axiomatic approach to geometry. We explore the geometry of the plane (“Euclidean geometry”) as well as the hyperbolic and spherical geometries which arise by tweaking what one means by “parallel”.
  • MA 425: Mathematical Analysis I
    MA 141, but we prove everything!
  • MA 508: Geometry for Secondary Teachers
    Originally developed for the MAP:TICCS grant from US Department of Education, this course explores the connections between school algebra and school geometry, picking up a lot of interesting things along the way. The glue that binds it all together is the notion of symmetry.
    Starting Fall 2017, this course is offered online.
  • MA 510: Topics for Secondary Teachers
    A MAP:TICCS course on mathematical modeling.
  • MA 518: Geometry of Curves and Surfaces
    The classical geometry of Gauss: curves and surfaces in \(\mathbb{R}^3\). The major theme is curvature. We spend a decent amount of time on minimal and constant-mean-curvature surfaces, as well as the famous Gauss-Bonnet Theorem.
  • MA 555: Introduction to Manifold Theory
    Same syllabus as MATH 600
at Michigan State
  • MTH 103: College Algebra
  • MTH 110: College Algebra and Finite Mathematics
  • MTH 124-126: Applied Calculus (two-course sequence covering applications of single- and multivariable calculus to business and biology)
  • MTH 132: Calculus I
  • MTH 234: Calculus III (multivariable calculus)
