Collaborators: Marianne Aubin Le Quere, Manoel Horta Ribeiro, Andy Guess, Tiffany Liu

Lead developer on Archively, an iOS app designed to support a study on digital well being by directing users to EMAs after completing Tiktok sessions and allowing users to upload their de-identified exported Tiktok data at the start and end of the study. Archively is built with a Flutter frontend and a FastAPI backend that utilizes Google Cloud services, such as Firebase Cloud Messaging, Data Store, and Cloud Run.

Pastcasting: Forecasting Historical Events with a Vintage LLM

Dates: – Present | Location: Princeton University

Collaborators: Liv d'Aliberti, Manoel Horta Ribeiro

Fine-tuned a 13B model with a 1931 training cutoff to test whether LLM forecasting accuracy degrades with temporal distance from training data.

Counterfactual Comments: A Cross-Platform Causal Design for Comment Toxicity

Dates: – Present | Location: Princeton University

Collaborators: Mehedi Zaman, Francesco Salvi, Jason Greenfield, Manoel Horta Ribeiro

This project investigates the causal effect of early comment-thread toxicity on subsequent toxicity, using a novel identification strategy to isolate toxicity spillover from content-level confounding.

Unscrambled: An EMA Platform for Studying Time Perception in Short-Form Video

Dates: – Present | Location: Princeton University

Collaborators: Manoel Horta Ribeiro

Designed a single-mechanic ecological momentary assessment platform collapsing measurement and intervention into a guess-then-feedback task on cumulative session time, delivered via iOS Live Activities.
