Research Summary

My research interests are human oral perception, its genetic basis and its implications in nutrition and health. Somatosensation, such as irritation and mouthfeel, is my main current focus through the study of natural products like wine, olive oil and spices. I am using several techniques to investigate the field of somatosensation, including molecular biology, cellular calcium imaging and psychophysics.


chemesthesis, mouthfeel, fluorescent calcium imaging, psychophysics, analytical chemistry, sensory transduction, oxidative stress, inflammation-related diseases
