Hello! My name is Seulgi, I'm a data journalist from Seoul, South Korea. I use data and graphics to tell stories about complex, often misunderstood issues in our society. I got started writing community dispatches, authoring realtime updates on public health protocols. I'm currently living in New York City and studying at Columbia University's Graduate program in Data Journalism, graduating in summer 2026.

I watch how a policy push to cut plastic waste rapidly transformed the ice-pack market, replacing gel packs with “greener” water-based alternatives. I follow the numbers behind that shift to show how quickly businesses adapted once environmental charges made plastic gel packs financially unattractive.
I trace how New York City’s winters have grown warmer over time, turning what once fell as snow into steady rain. I follow decades of climate data to show the quiet but persistent shift from snowy seasons to increasingly rain-soaked winters.
I map how the number of detainees held across U.S. states has changed over time, using state-level data to reveal patterns in detention. I explore trends in incarceration counts to show where and how detention populations have grown or declined.
This piece explores how the work of Han Kang, the 2024 Nobel Prize laureate in Literature, reached her contemporary readers and fellow citizens when the unprecedented martial law was activated by the modern tyrant Yoon Seok-yeol.
I got a hint for this project from a presentation by Mr. Suh Jae-jeong, a professor in the Department of Politics and International Studies at International Christian University, clearing the North's true intention amid the current security crisis on the Korean peninsula. I used Mapbox Scrollytelling template and added some structural changes using Javascript. Satellite images were gained from Google Earth.
I covered a soaring xenophobic phenomenon in Korea, singularly targeting Korean Chinese, called joseon-jok. I used Selenium to scrape data and Python to refine it. The graph was created with free Javascript source, and ai2html & Scrollama were used for the other graphic. Korean translation is available for this piece.
