About Me

I am an Acting Assistant Professor (i.e., a postdoc) in the Department of Mathematics at the University of Washington working with Rekha Thomas.

Here is my **CV**.

I am interested in anything related to combinatorial optimization, operations research, applied algebraic geometry, proof complexity and polyhedral combinatorics.

**Past** - Before coming to the University of Washington in the fall of 2014, I completed a Ph.D. in mathematics under the supervision of Martin Grötschel at the Technische Universität Berlin. My thesis was on ''Polyhedral Methods Applied to Extremal Combinatorics Problems''. During my time in Berlin, I was also a member of the Berlin Mathematical School and of the Zuse Institute Berlin, an interdisciplinary research institute for applied mathematics and data-intensive high-performance computing. Prior to that, I was a student at the Massachusetts Institute of Technology where I completed a bachelor of science in mathematics as well as a bachelor of science (!) in music. During that time, I participated in the Undergraduate Research Opportunities Program at MIT and in two summer research programs, one funded by the NSERC and the other by the LaCIM, both in my hometown at the Université du Québec à Montréal.

**Future** - I will spend the fall semester of 2017 at MSRI for the program on Geometric and Topological Combinatorics. Afterwards, I will start a tenure-track position at UMass Amherst. In the meantime, you can find me at the following conferences and workshops:

SIAM Conference on Optimization in Vancouver (May 22-25, 2017)

SIAM Conference on Applied Algebric Geometry in Atlanta (July 31 to August 4, 2017)

Oberwolfach Workshop on Proof Complexity and Beyond in Germany (August 13-19, 2017)

**Spring Semester 2017: MATH 106 College Algebra** 11 students + 3 auditors. This class is taught through University Beyond Bars, an organization providing higher education to people in prisons. The students earn credits for this course through Adams State University. This course is meant to be an introduction to the basic techniques of algebra. Topics include functions, systems of equations, matrix algebra, inequalities, and complex numbers. Weekly homework, four midterms, one final, two hands-on projects where the students applied what they learned to their daily lives.

**Fall Semester 2016: Lecture Series on Proofs from the Book** This lecture series was organized through University Beyond Bars. It provided an introduction to the world of mathematical proofs.

**Spring Semester 2016: MATH 104 Finite Mathematics** 16 students + 4 auditors. This class was taught through University Beyond Bars, and students earned credits through Adams State University. This course covered some introductory topics in combinatorics, probability, statistics, linear algebra and optimization. Weekly homework and quizzes, one midterm, one final, two hands-on projects where the students applied what they learned to their daily lives.

**Spring Quarter 2017: MATH 300 Introduction to Mathematical Reasoning** 32 students. An introduction to mathematical arguments and the writing of proofs through topics in elementary set theory, graph theory and number theory. Weekly homework and quizzes every other week, one midterm, one final.

**Spring Quarter 2017: MATH 324 Advanced Multivariable Calculus** 50 students. As below.

**Winter Quarter 2016: MATH 498A Special Topics in Mathematics ** 1 student. Reading course with an undergrad student on approximation algorithms.

**Fall Quarter 2016: MATH 324 Advanced Multivariable Calculus** 100 students over two sections. As below.

** Spring Quarter 2016: MATH 409 Combinatorial Optimization** 27 students. This course covered various topics connected to matchings and matroids from a polyhedral perspective. Weekly homework and quizzes, one midterm, one final.

**Spring Quarter 2016: MATH 498 Special Topics in Mathematics ** 1 student. Research with an undergrad student on the union-closed sets conjecture.

**Winter Quarter 2016: MATH 324 Advanced Multivariable Calculus** 92 students over two sections. As below with the addition of ASK or Annie's Survival Kit, three extra problems with carefully written out solutions sent weekly to better prepare the students for the quizzes. An extra ASK office hour right before the quiz was also added where I went over the problems and showed my thought process.

**Fall Quarter 2015: MATH 324 Advanced Multivariable Calculus ** 88 students over two sections. As below with the removal of one midterm and the addition of two extra-credit projects. The first one asked students to find out about an application of multivariable calculus relevant for their future career or their interests. The second one asked them to use Lagrange multipliers to optimize something in their lives.

**Spring Quarter 2015: MATH 308 Matrix Algebra With Applications** 49 students. As below with the addition of an extra-credit project where the students had to think about an advanced application of linear algebra (i.e., not just solving) relevant for their future career or their interests.

**Winter Quarter 2015: MATH 308 Matrix Algebra With Applications** 46 students. This is an introduction to linear algebra which covered solving systems of linear equations, matrix algebra, vector spaces, orthogonality, least squares, eigenvalues, diagonalization.
