Researcher on privacy decision-making and recommender systems. Our online lives are full of small but difficult decisions. Which app should I install? Should I post this on Facebook or not? Which YouTube video should I watch? What will this e-commerce website do with my personal information? In my research I try to understand the psychological principles behind these online decisions. Using Big Data and Machine Learning principles, I try to make these decisions a little easier with better user interfaces and "smart defaults".
