Current Course ("Winter" 2020)
Here is a recent teaching statement: Kemp-Teaching-2016.pdf
UC San Diego, 2010 - Present
- Introduction to Probability Theory: in Fall 2019, Winter 2016, and Fall 2010, I taught Math 180A. I used "Elementary Probability for Applications" by Rick Durrett.
Topics included probability spaces, combinatorial probability, conditional probability, random variables, discrete and continuous probability distributions, joint distributions, independence,
variance and moments, the Laws of Large Numbers, and the Central Limit Theorem. The Fall 2019 version of the course was an experimental "Data Science flavored" course, which included a few
extra topics (confidence intervals, moment generating function, Poisson process) and included an additional Python-based lab component (through Jupyter Notebooks) devoted to real-world
data sets and their analysis using probabilistic ideas.
- Lie Groups: in Winter and Spring of 2019 and 2015, I taught Math 251B/C, a two quarter topics graduate course on Lie Groups.
Topics included basics of Lie groups and group actions, Lie algebras and left-invariant vector fields, the exponential map and adjoint maps, normal subgroups and ideals,
the Baker-Campbell-Hausdorff formula, the Lie correspondence, quotients and covering groups, the Lie-Cartan theorem, compact groups and maximal tori, the Weyl group, Cartan's
torus theorem, the Weyl integration formula, basic representation theory, representation theory of semisimple Lie algebras, representative functions and characters
for compact groups, and the Peter-Weyl theorem. I sampled from several sources, and I produced lecture notes (combined for this course and the preceding course on differential
geometry) which can be downloaded here.
- Differential Geometry: in the Fall of 2018 and 2014, I taught Math 250A: the first graduate quarter course in differential geometry.
Topics included: a review of topics from calculus and differential equations; topological manifolds; smooth structures, smooth maps; tangent spaces and the
tangent bundle, differentials; vector fields, push forwards, Lie brackets; flows, Lie derivatives; the cotangent bundle, 1-forms, line integrals, and the Poincare lemma.
The textbook was be Introduction to Smooth Manifolds by John M. Lee.
- Stochastic Differential Equations: In Fall 2018, I taught Math 286, an advanced graduate course on stochastic integration and stochastic differential equations.
Topics included the stochastic integral with respect to a square integrable martingale integrator, the Ito / Doleans isometry, extension to local martingales and semi-martingales,
quadratic variation and the Doob-Meyer decomposition, Ito's formula with applications to stochastic processes, the Feynman-Kac formula and other applications to PDE and harmonic analysis,
Brownian local time, martingale representation theorems, and introduction to stochastic differential equations: strong existence and uniqueness for locally Lipschitz and sublinear growth
drift and diffusion, weak solutions, and the Cameron-Marton-Girsanov theorem. We loosely follows the textbook "Introduction to Stochastic Integration" by Chung and Williams.
- Linear Algebra: In Winter 2018 and Winter 2017, I taught Math 18, and in Fall 2012 I taught Math 20F (a previous version of the same course).
There were 180 students in 2012, 310 students in 2017, and more than 400 (bewtween two lectures) in 2018.
Topics included: Matrix algebra, Gaussian elimination, determinants; linear and affine subspaces, bases of Euclidean spaces; eigenvalues and eigenvectors, orthogonal matrices,
orthogonal projections, and diagonalization of symmetric matrices. The course included a regular Matlab component emphasizing the computational aspects of the material.
The textbook was "Linear Algebra and Its Applications", by David C. Lay.
- Quantum Mechanics (for Mathematicians): In Spring 2017, I taught a topics graduate course, Math 247A. The topic was quantum mechanics, from a rigorous
functional analytic viewpoint. Topics included a review of Hamiltonian mechanics, the key experiments of early 20th Century physics that necessitated quantum mechanics, the Borh-de Broglie
"old quantum theory", the position and momentum operators (with careful domain analysis), the axioms of quantum mechanics, Schrodinger's equation, the quantized harmonic oscillator, the
Heisenberg uncertainty principle, and a detailed analysis of the bound states of the Hydrogen atom (developing the necessary tools from the representation theory of SO(3) along the way).
This was a very popular course, with almost 60 students attending and over 25 enrolled for a letter grade at the end (which required a final term paper and final exam to be completed).
The textbook was Quantum Mechanics for Mathematicians by Brian Hall.
- Functional Analysis: In Winter 2017 and Fall 2016, I taught Math 241A and 241B, a two quarter sequence on functional analysis. In the first quarter,

on Hilbert spaces and Banach spaces, commutative C* algebras, and the Spectral Theorem for (commuting families of) normal operators on Hilbert spaces. The second course focused largely
on unbounded operators, up to and including the spectral theorem for selfadjoint unbounded operators, and concluding with the Hille-Yosida theorem on
strongly continuous contraction semigroups. Some of this material is in Chapter 10 of Conway, but I largely used outside sources (primarily notes from Bruce Driver and Leonard Gross).
- Foundations of Real Analysis II: in Spring 2016, I taught Math 140B, the second quarter of real analysis, as taught out of chapters 5-8 in

CURE: Collaborative Undergraduate Research Experience
Under the aegis of my NSF CAREER Award, I run a summer research program each year for 4-5 undergraduate math majors.
Information about the program in general and current and past projects can be found here.
Research Experience for Undergraduates
In Summer 2007, I ran an (NSF-funded) REU project at Cornell University. The topic was
The Combinatorics of Free Probability. In studying *-moments of circular operators, we found a new and interesting family of convex posets associated to random
strings and non-crossing partitions.
