Teaching
I've always enjoyed teaching and I am convinced that given the right support every student is capable of learning and success. In the classroom I always try to create a pleasant atmosphere where questions are encouraged. Evaluations and comments by colleagues and students about my teaching are available here.

Previous courses

Math 8: Calculus in One and Several Variables This course is a sequel to Math 3 and provides an introduction to Taylor series and functions of several variables. The first third of the course is devoted to approximation of functions by Taylor polynomials and representing functions by Taylor series. The second third of the course introduces vector-valued functions. It begins with the study of vector geometry, equations of lines and planes, and space curves. The last third of the course is devoted to studying differential calculus of functions of several variables.

Math 35: Real Analysis Real analysis is a formal, mathematical study of the basic objects of calculus. In the first part we treat real numbers, functions, sequences and limits and in the second part differentiation and integration. We will revisit this material from calculus, taking a more abstract and mathematically sophisticated approach. In addition to learning real analysis, students will improve their skills in reading mathematics and in writing proofs. The course finishes with an outlook on Fourier series.

Math 31: Topics in Algebra This course provides an introduction to fundamental algebraic structures. The majority of the course will consist of the study of groups, rings and fields. Additionally, to better understand groups from a geometric point of view, we will look at their representation as a Cayley graph. Finally, the aim of the hands-on project will be to find a solution to the 2x2 Rubik's cube and to understand its connection with abstract algebra.

Math 13: Multivariable Calculus This course is a sequel to Math 8 and provides an introduction to calculus of vector-valued functions. The course starts with iterated, double, triple, and surface integrals including change of coordinates. The remainder of the course is devoted to vector fields, line integrals, Green’s theorem, curl and divergence, and Stokes’ theorem.

Math 22: Linear Algebra This course presents the fundamental concepts and applications of linear algebra. Topics include bases, subspaces, dimension, determinants, characteristic polynomials, eigenvalues, eigenvectors, and especially matrix representations of linear transformations and change of basis. As an application we will study Markov chains, Google's PageRank algorithm and the JPEG image compression. In this course the students will develop the ability to perform meaningful computations and to write accurate proofs.

Math 3: Calculus This course aims to prepare the students to use calculus in many other disciplines without losing sight of its theoretical value. This course is an introduction to single variable calculus and is intended for students who are planning to go on to Math 8. Topics include, but are not limited to limits, continuity, derivatives, definite and indefinite integrals over the real line. The jewel of this course is the Fundamental Theorem of Calculus and it will be used to develop some techniques of integration.

Math 112: Geometric Group Theory By associating a group to one of its Cayley graphs, the properties of a group can be studied from a geometric point of view. The group itself acts on the Cayley graph via isometries which is reflected in the symmetries of the graph. The inherent beauty of a group can thus be visualized in its Cayley graph making these graphs a fascinating object of study. Geometric group theory examines the connection between geometric and algebraic invariants of a group. In order to obtain interesting invariants one usually restricts oneself to finitely generated groups and takes invariants from large scale geometry.
Geometric group theory closely interacts with low-dimensional topology, hyperbolic geometry and differential geometry and has numerous applications to problems in classical fields, like combinatorial group theory, graph theory and differential topology.
