The Davis Sensory Institute. LLC, provides food, beverage, and personal care companies with a unique partner in their sensory and consumer research projects. Prior to the start of DSI, for over 25 years we conducted fundamental and applied research at the University of California, Davis, resulting in a world-renowned sensory science laboratory. Our investigations touched all aspects of the field, from discrimination testing (with pioneering work on Thurstonian models and the tetrad test) to the optimization of descriptive analysis methodologies and the improvement of preference testing investigations.
