About

Behavioral science, computation, and applied AI.

Most of my work starts from the same problem: people make judgments from messy, incomplete, socially loaded information. As a quantitative behavioral scientist I run experiments, model messy human data, and analyze language at scale to study how that actually works. As a builder I turn the same questions into AI workflows where evidence, context, and human review stay close to the decision being made.

Capabilities

What I’m fluent with.

What I reach for when a question moves from idea to evidence to product. It’s usually me at every stage — designing the study, writing the analysis, building the retrieval system, shipping the work.

Engineering & tools

What I actually ship in — the stack I use day-to-day, from research pipelines to product systems.

Applied AI & product systems

How I use machine learning and large language models in real workflows — at scale, with retrieval, evaluation, and humans still in the loop.

Statistics & research methods

How I turn an ambiguous behavioral question into a study design and an analysis I can defend.

M.S. Statistics and Data Science

Graduate training

My bridge from psychology to industry-facing data science.

B.A. Psychology; minor in Composition & Rhetoric

Undergraduate education

My undergraduate foundation in psychology and writing/rhetoric.

Beyond publications

Applied work, teaching, and talks.

A lot of what I actually spend time on doesn’t live on a CV line — consulting with researchers on their data, teaching and mentoring, and going to talk about my work 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.
