Hello! I'm Aryan Rezanezhad

Sep 2023 - Aug 2024

Teaching and Research Assistant

University of Western Ontario (London, ON)

Developed the R package ATE.ERROR to enhance treatment-effect estimates by correcting for measurement error and misclassification under the supervision of Prof. Grace Yi. Assisted with grading and conducted office hours for the Data Science Concepts course serving 120 students, collaborating with Professors Camila de Souza and Ashley McAlpine.

I'm a Data Analyst with an M.Sc. in Statistics from Western University, skilled in Python, R, SQL, and Azure. With a strong foundation in statistical analysis and data management, I transform complex datasets into actionable insights, create interactive Power BI and Tableau dashboards, and build efficient data pipelines that drive evidence-based decisions and measurable outcomes. Passionate about continuous learning, I stay current with industry trends and have earned multiple professional certificates while always exploring new tools and techniques.
