About Me

I'm a data scientist and fellow in the Insight Data Science program.

Previously I was a climate scientist at MIT, where I ran numerical climate models to study climate change with Paul O'Gorman. I applied machine learning algorithms, like artificial neural networks and random forests, to emulate the convection scheme in climate models to improve speed and performance.

For my PhD in Applied Math at Columbia University, I quantified projected 21st century changes to the annual cycle of temperature and precipitation with my advisors, Michela Biasutti and Adam Sobel.
