Hi there, I'm Cem!

I am a postdoctoral researcher at New York University Abu Dhabi. My interests lie in Decision Sciences and Behavioral Economics.

Here are some of the questions in my agenda:

Decisions in policy/business often rely on surveys & subjective feedback. How can we ensure self-reported data is reliable?
Expertise is elusive. Can we consistently identify experts in judgment/decision problems?
Studies in the wisdom of crowds suggest that aggregating diverse judgments improves decision/prediction accuracy. How should we combine disagreeing judgments for best results?
