Senior Researcher at Vanderbilt University - Owen Graduate School of Management·2022 – now

Studying why consumers resist AI in conversation

At Owen I study how consumers make inferences, lately how conversational norms shape AI aversion.

Talk to me about
Epistemic inference theory

Turned my dissertation into a theory of uncertainty

Missing knowledge leads people to draw inferences. Randomness makes those inferences less useful.

Talk to me about
Research·2023

Found people who wait a week feel surer but know less

In three experiments, people who delayed deciding forgot what they'd learned yet felt more confident.

Talk to me about
Consumer Marketing Insights (CMI) Lab Director at University of Cincinnati Carl H. Lindner College of Business·2020 – 2021

Studied whether death reminders make people obey signs

As COVID death counts rose, we tested how mortality salience shapes how people judge handwashing signs.

Talk to me about
Ph.D., M.Sc., and B.B.A. in Marketing at University of Cincinnati·2016 – 2021

Earned three degrees at one school, ending in a PhD

A BBA, a master's, then a PhD on the duality of subjective uncertainty, chaired by Frank Kardes.

Talk to me about
TEDxUCincinnati·2020

Grew up watching TED, then gave a talk on missing info

My mentor Frank Kardes and I spoke at TEDxUCincinnati. The theme, 'off the record', fit my research perfectly.
