Current Research

Our lab’s current research is centered around four main areas:
1. We are interested in addressing food perception changes in anosmics and look for methods to increase their eating enjoyment. Approximately 5% of people don’t have a sense of smell (anosmia), which has been shown to drastically decrease their eating enjoyment. We are currently collecting data on food attitudes in anosmics with plans to use this feedback to design foods for anosmics.
2. We are interested in characterizing oral tactile sensitivity and finding relationships between oral tactile sensitivity and oral processing. Currently, there isn’t a standardized method to measure how sensitive to touch someone is within their mouth. We are working to develop a test to measure the food-related touch sensations involved texture perception.
3. Research assessing how crossmodal correspondence and other multisensory phenomena manifest themselves in real food/beverage consumption situations. When we sit down for a meal we are constantly inundated with sights, sounds, smells, and tastes that create our eating experience. These sensations are not processed independently, inputs from one modality influence the perception in another. These interactions are well laid out in the lab setting, but our lab is looking at how useful these interactions are for changing the perception of food/beverage in a real setting.
4. Development and characterization of retronasal aroma perception. Odors can be perceived from both the nose (orthonasal) and mouth (retronasal). Almost all characterizations of how humans perceive smell stimuli is done through orthonasal presentation routes. In the food industry, retronasal odor perception if extremely important. We are working on ways to assess retronasal aroma and characterize human retronasal olfactory ability.
