Join UC Davis and Curion as we honor and celebrate the 50th anniversary of the industry revolutionary Quantitative Descriptive Analysis (QDA) methodology.

Developed in 1974 by Dr. Herbert Stone and Joel Sidel, QDA was the catalyst that sparked Curion’s rich history of delivering consumer and sensory insights to global brands.

The importance of QDA Day

The QDA methodology transformed product testing by placing human perception at the center of research. Originally applied within the food industry, this approach relies on trained panels to identify, describe, and quantify key attributes using their own words. Over five decades, QDA has advanced industries ranging from foods and beverages to personal care, household products, and beyond, laying the groundwork for the robust, data-driven solutions Curion provides today.

QDA Day: A legacy worth celebrating

Fifty years later, we gather to recognize the lasting impact QDA has made on product development, consumer insights, and sensory science. At this special UC Davis event, you’ll learn how the QDA framework continues to adapt to emerging market trends and consumer behaviors, ensuring product excellence every step of the way.,
