Cory K. Costello

Senior Data Scientist

Nielsen Corporation

I am Psychological Scientist by training, currently working as a Senior Data Scientist at the Nielsen Corporation, where I use my expertise in statistics, data science, and behavioral science to contribute to Nielsen’s audience measurement products. I was previously a postdoctoral fellow in the Emotion and Self-Control Lab (PI: Ethan Kross) at University of Michigan’s Department of Psychology. Prior to that, I was a PhD student in the Personality and Social Dynamics Lab (PI: Sanjay Srivastava) at the University of Oregon’s Department of Psychology. I spent my time in academics learning to apply complex data analytic techniques - social network analysis, predictive modelling / machine learning, text analysis, structural equation modelling, hierarchical linear modelling - to answer questions about personality, emotion, and reputation.
