Ruth A. Shaffer
Data Scientist 3 | Reliability Analytics & Data Science Team
Comcast Corporation

Biography

I’m a Data Scientist at Comcast Corporation on the Reliability Analytics & Data Science team. I'm passionate about using data science and machine learning to generate insights that address both theoretical and real-world problems. As a data enthusiast and former graduate student researcher in Experimental Cognitive Psychology, I’ve gained extensive experience with quantitative analysis, advanced statistical modeling, and communication, leveraging my undergraduate minor in Computer Science to use a variety of programming languages and statistical software (e.g., R, Python, SQL, MATLAB, JavaScript, SPSS) to suit the problem at hand.

Before joining Comcast, I graduated from Washington University in St. Louis with a Master's Degree in Psychological & Brain Sciences and a Graduate Certificate in Quantitative Data Analysis, where I explored the mechanisms that underlie retrieval from long-term memory. As a graduate student I was a National Science Foundation Graduate Research Fellow and a United States Scholar in the McDonnell International Scholars Academy.

Prior to graduate school, I completed a B.A., summa cum laude, in Psychological & Brain Sciences (concentration in Cognitive Neuroscience) and a minor in Computer Science at Washington University in St. Louis.
