About

Behavioral science, computation, and applied AI.

Most of my work starts with the same problem: people make judgments from incomplete, socially loaded information. I use experiments, statistical modeling, and large-scale language analysis to understand those judgments. The systems I build come from the same interest in how people find and use information.

Capabilities

What I’m fluent with.

The questions change, but my work often spans the full path from study design and analysis to retrieval systems and product implementation.

Engineering & tools

The tools I use to build research pipelines, analyses, and product systems.

Applied AI & product systems

Machine learning, language models, retrieval, and evaluation for work built around documents and decisions.

Beyond publications

Applied work, teaching, and talks.

Much of my work also happens outside papers: consulting with researchers on difficult data, teaching and mentoring, and presenting at universities and conferences.

Consulting

Northwestern IT Research Computing

I’m a Data Science, Statistics, and Visualization Student Consultant. I work with researchers across Northwestern to figure out what to do with ambiguous data, build analyses in R and Python, and turn results into decisions they can act on.

Teaching

Northwestern & Harvard Extension

I’ve been a teaching assistant at Northwestern and at Harvard Extension School, including graduate-level material on bias, defensiveness, self-regulation, and quantitative methods.

Mentoring

Undergraduate researchers

I’ve mentored 15+ undergraduate research assistants and honors thesis students through my first-author projects in social cognition, moral judgment, and computational behavioral science.
