COVID-19 Outbreak Detection in Food Establishments Using Web Scraping and RoBERTa

A proof-of-concept, human-in-the-loop pipeline to scrape news articles from the web using keywords, classify them as relevant or not to COVID-19 outbreaks in food establishments using a fine-tuned RoBERTa model, and output the most relevant articles for human review. Published a first-author paper at the Artificial Intelligence in Medicine conference in collaboration with internal GTRI partners and members of the Centers for Disease Control and Prevention (CDC).

Diabetes Readmission Dashboard
ReaDash is an interactive dashboard displaying information relating to diabetes patients' hospital readmissions. The user can visualize plots related to features predictive of hospital readmission, interact with a machine learning model (logistic regression) in order to download predictions for their own dataset, and visualize the performance of various machine learning models in predicting hospital readmission for patients with diabetes.

Medication Review Modeling
A group project studying the relationship between medication review text, metadata, and review usefulness. My focus in this project was exploratory data analysis and training of text-only DistilBERT models to process the text and hybrid DistilBERT models for joint text and metadata processing. Overall, we were able to predict review usefulness successfully from both the text only and the metadata only, but the hybrid model performed best.
