Hey, I'm Kat de Jesus Chua.

I'm the AI Research Lead for the Associated Press.

I'm a data scientist and writer interested in AI, journalism, and public data.

I was a 2025 Gary Marx Scholarship winner with Investigative Reporters and Editors, recognized for my volunteer work with the Data Liberation Project, building Python pipelines to preserve public data. I also cover local government meetings as part of City Bureau's Documenters network. You can find notes I've written here.

Previously, I was a Data Scientist at Warner Bros. Discovery, where I specialized in natural language processing and applied machine learning for media content. I graduated in 2020 with a B.A. in Data Science from the University of California, Berkeley. Find my resume here.

He was quite unmoved by my nonsense. Solid guy.

Chicago Documenters

Covering Chicago Government Meetings

As a Documenter, I attend and take notes on Chicago's public meetings.

These notes support City Bureau's reporting and provide Chicagoans a record of what happens in local government meetings, neighborhood councils, and courthouses in their city.

Data Liberation Project

Preserving Public Datasets

Vast quantities of government data exist in inaccessible, difficult-to-analyze formats. This data is also vulnerable to removal or manipulation by bad actors.

As a volunteer, I build webscraping and data cleansing pipelines to preserve this data for the public good.

Another Chicago Magazine

Reviewing Fiction Submissions

I review short story submissions for Another Chicago Magazine, recommending pieces for publication.

Previously, I served as a Fiction Reader for Same Faces Collective, where I evaluated submissions and nominated outstanding work for the 2025 Pushcart Prize.

Invisible Institute

Beneath the Surface: Coding Police Complaints

In a volunteer team, I coded Chicago police complaint records, assigning labels such as domestic violence, location, and presence of a child, and documenting questions and themes that arose for me.

The resulting structured data will support the Invisible Institute's future investigations and police accountability projects.

Illinois Network for Pretrial Justice

Building a Pretrial Fairness Act Dataset

INPJ, in collaboration with City Bureau's Chicago Documenters, launched a court-watching pilot, collecting data on pretrial detention hearings at Cook County Criminal CourtHouse.

Using Python, I am creating a structured dataset and performing actionable analysis for journalists, researchers, and advocates.

TSA Complaint Data Disappeared

At the start of Trump's second term, the TSA removed years of complaints reports from its website.

I covered the removal and how Data Liberation Project's archive of TSA complaints data can fill the gap.
