With over 10 years of research experience, I've dedicated my career to understanding how culture and society influence individuals' attitudes and behaviors. My experiences range from managing multi-million dollar international studies to extracting actionable insights on diversity and inclusion in the workplace. I adopt a mixed-methods approach in my study designs, employing both quantitative and qualitative research techniques where appropriate. Collaboration is at the heart of my approach, integrating diverse perspectives and lived experiences to ensure that every piece of research is adequately nuanced, meaningful, and actionable.

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.
