Modeling Healthcare Outcomes Using Real-world Data
Cover image for First Author & Data Scientist
First Author & Data Scientist | Presented at the American Epilepsy Society Annual Meeting Led the quantitative analysis of epilepsy's multidimensional impact on Veterans' lives using the Personal Impact of Epilepsy Scale (PIES). Built regression models to identify patient and clinical characteristics most strongly associated with seizure, medication, and comorbidity burden and quality of life outcomes. Developed all data visualizations in R and ggplot2. Key findings included a consistent association between seizure frequency and negative epilepsy impact, and age effects aligned with broader quality-of-life literature.

Cover image for I was the lead data
I was the lead data analyst on a peer-reviewed cardiology study with Dr. Kevin Shah, examining disparities in COVID-19 clinical trial enrollment across sex, race, and ethnicity. Using R, I performed descriptive analysis and built multivariable models on 14k+ hospitalized patients from the AHA COVID-19 CVD Registry. The study revealed lower enrollment for Black and female patients, highlighting equity gaps in clinical research and the value of rigorous healthcare data analysis.

Cover image for AI coding agents are fast.
AI coding agents are fast. They're also great at accumulating redundant functions, ignoring pipeline integrity, leaking features in ways that look fine until they don't, and writing code that technically runs but nobody could maintain. This is a human review, by a practitioner with 6 years of healthcare data science experience, specifically for codebases where agents have been doing the building. https://contra.com/products/UXcU8hy7-human-code-review-data-science-and-machine-learnig
