Juan Herrera

I'm a Data Scientist at NBCUniversal and a graduate student at University of Southern California.

In the past, I worked at Nestlé Purina and Eventellect.

I've worked on building machine learning and statistical models, as well as causal inference analyses.

I'm constantly seeking to understand the 'why' behind things, and as a result, I write about what I learn in the process on Medium and Substack
