Eliciting Truth in the
Information Age

We explore the intersection of Theoretical Computer Science and Economics (EconCS), designing mechanisms to aggregate information and benchmark intelligence.

Research Areas

Information Elicitation

In the absence of ground truth, how can we incentivize participants to provide truthful information (Peer Prediction)? How do we evaluate the quality of information and predictions?

Prediction Markets

Designing market mechanisms to aggregate dispersed information for accurate forecasting of future events.

Mechanism Design

Designing incentive-compatible mechanisms where maximizing individual interest aligns with system goals.

Applications to Crowdsourcing & ML

Robust aggregation against adversarial experts, benchmarking LLMs' judgments with information-theoretic methods, and exploring AI-Human collaboration.
