Alexandra Cosso
I help organizations make sense of complex data using R. I’ve spent the last decade working with data in public health, clean energy, and government, often at national or statewide scale. My work ranges from leading analytics teams responsible for billions of rows of data to hands-on R development and visualization.
Alongside my applied work, I teach and train. I’ve supported graduate-level R courses at Columbia University and currently work with professional training organizations to help industry data teams strengthen their skills in R, SQL, and analytics best practices.
