About

I am a health data scientist with a PhD in Epidemiology interested in applying causal inference and prediction models for adverse outcomes in vulnerable individuals. I am fascinated by the implementation, understanding, and utility of various data sources that capture further layers of the complexity of human health. Lately I am researching in Science of Science, and the use of AI tools to quantify measures of interdisciplinarity and its impact on academic endpoints. I also love pepperoni 🍕 pizza and salted caramel 🥤 oat lattes.
