I am a data-driven psychological scientist with expertise in how culture and society shape individuals’ attitudes and behavior, and how this varies by demographics and lived experiences. I have 10+ years of experience in research, project management, survey design and measurement, data analytics, data visualization, quality control, data management, and science communication. My projects are collaborative and employ quantitative and qualitative methods, including analyses in SPSS, R, and Displayr.

In my academic research, I explored how the cultural context shapes how individuals reason and explain the world around them, and how beliefs and attitudes form and change or remain stable. I took a lifespan perspective in much of this work by examining how both children and adults think. 


I employed both quantitative and qualitative methods as well as a variety of research designs and techniques to answer research questions, including: longitudinal and cross-sectional designs, experimental and observational studies, focus groups, semi-structured qualitative interviews, surveys, and cognitive tasks.
