## Nonparametric Methods

Nonparametric and semiparametric Bayesian models use prior distributions defined in infinite-dimensional spaces to relax some of the standard assumptions made by standard statistical methodology.

## Network and Relational Data

I am interested in models for network and relational data.

## Political Science

I am interested in models for revealed preferences that relax some of the typical assumptions used in the literature, such as ignorable missingness and invariance of preferences.
