Hannah Mieczkowski, PhD


I am a mixed-methods social scientist with nearly a decade of research experience, including four years of UX/HCI research in the tech industry. In June 2022 I graduated with my PhD from Stanford University. I currently work as a Senior User Experience Researcher at ZS.

I use both quantitative and qualitative methods - such as surveys, experiments, think-aloud studies, interviews, and text analysis. My subject matter expertise is in investigating the connections between people’s perceptions, emotions and behaviors towards social technologies.
