About Barthelemy


Bio

I hold an M.S. in Economics from Baylor University and recently completed a research fellowship at Columbia University's Department of Economics. While at Columbia, I also completed the graduate Real Analysis sequence (Intro to Modern Analysis I and II), covering metric spaces, convergence, compactness, continuity, Riemann integration, power series, analytic functions, contraction mappings, and Lebesgue measure. I also took Introduction to Higher Mathematics, which covered proof techniques,...

I hold an M.S. in Economics from Baylor University and recently completed a research fellowship at Columbia University's Department of Economics. While at Columbia, I also completed the graduate Real Analysis sequence (Intro to Modern Analysis I and II), covering metric spaces, convergence, compactness, continuity, Riemann integration, power series, analytic functions, contraction mappings, and Lebesgue measure. I also took Introduction to Higher Mathematics, which covered proof techniques, logic, set theory, and cardinality. Before Columbia, I spent a year at the World Bank as a research fellow, applying econometric and statistical methods to real-world policy questions. My academic training spans economics, statistics, and proof-based mathematics, and I am fluent in both English and French.
I tutor because I genuinely enjoy watching someone go from confused to confident. Math isn't about memorization — it's about learning to think clearly, and that's a skill that transfers to everything else in life. Whether you're struggling with Algebra 1, preparing for the SAT or GRE, or working through your first proofs in Real Analysis, my approach is the same: understand what you already know, figure out exactly where the gap is, and build from there. I don't move on until you actually get it — not just nod along. I believe every student can succeed in math with the right guidance, and I take pride in being patient, direct, and genuinely invested in your progress.
I am comfortable working with students at any level, from high school through graduate school. I have experience supervising and training research assistants at Columbia, which has sharpened my ability to explain complex ideas in simple, accessible language. I offer both in-person and online sessions to fit your schedule and learning style.

Approved Subjects

Econometrics

Econometrics

I hold an M.S. in Economics from Baylor University, where I completed Econometric Theory, Causal Inference, and Mathematical Statistics. I spent three years at Columbia University's economics department and one year at the World Bank applying econometric methods including difference-in-differences, regression discontinuity, instrumental variables, and randomized controlled trials to real-world research questions. I can help with problem sets, Stata/R implementation, exam preparation, and building intuition for causal inference at the undergraduate or graduate level.
Logic

Logic

I completed the graduate Real Analysis sequence (Intro to Modern Analysis I and II) at Columbia University, covering metric spaces, convergence, compactness, continuity, Riemann integration, power series, analytic functions, contraction mappings, and Lebesgue measure. I also hold an M.S. in Economics from Baylor University, where I took Mathematical Statistics and Computational Methods. I can help with proofs, problem sets, and exam preparation for undergraduate or graduate-level Real Analysis courses.
Real Analysis

Real Analysis

I completed the graduate Real Analysis sequence (Intro to Modern Analysis I and II) at Columbia University, covering metric spaces, convergence, compactness, continuity, Riemann integration, power series, analytic functions, contraction mappings, and Lebesgue measure. I also hold an M.S. in Economics from Baylor University, where I took Mathematical Statistics and Computational Methods. I can help with proofs, problem sets, and exam preparation for undergraduate or graduate-level Real Analysis courses.
