About

A researcher's
perspective.

I started with stories, then became interested in the patterns behind them.

Journalism and political science drew me to questions about people and institutions. Studying Data Science gave me another way to investigate those questions: cleaning data, testing relationships, and making findings easier to understand.

I’m completing a B.S. with majors in Data Science and Political Science at The George Washington University. I’m graduating in December 2026.

Tools

Python R SQL / SQLite Excel (openpyxl) R Shiny Streamlit Neo4j / Cypher

Methods
