Research Interest
Dr. Toshi Matsuda’s research interests focus predominantly on olfactory and gustatory perception, specifically in the clinical evaluation and validation of sensory function tests. His work has contributed to advancing diagnostic methodologies for smell and taste disorders, conditions often overlooked despite their critical importance in overall health and quality of life. He has consistently explored the physiological and pathological mechanisms underlying chemosensory disturbances, particularly in patients with chronic sinusitis, elderly populations, and individuals with neurologically related sensory impairments. Dr. Matsuda has also contributed significantly to the development and cross-cultural adaptation of diagnostic tools, such as the Japanese version of the University of Pennsylvania Smell Identification Test (UPSIT), helping localize globally accepted tests for the Japanese population. He remains interested in electrogustometry, a technique used to assess taste thresholds via electrical stimulation, and continues to examine its validity and clinical utility. His collaboration with leading researchers in the U.S. and Japan underscores his commitment to scientific rigor and interdisciplinary research. By combining physiology, diagnostic technology, and cross-cultural considerations, Dr. Matsuda aims to enhance the accuracy and accessibility of sensory disorder diagnoses, thereby contributing to improved patient outcomes in otolaryngology and general healthcare.
Research Skills
Dr. Toshi Matsuda possesses a comprehensive set of research skills grounded in both laboratory and clinical methodologies, particularly within sensory physiology and otorhinolaryngology. He is proficient in designing and conducting electrogustometric and olfactometric studies, which involve quantitative assessments of taste and smell sensitivity. His research has incorporated electrode-based stimulation, threshold determination, and cross-comparative validation techniques, particularly in relation to bipolar electrode use and stimulus duration effects. Dr. Matsuda is skilled in both qualitative and quantitative data analysis, with experience in conducting clinical trials and patient surveys, particularly among elderly and sinusitis-affected populations. His technical expertise includes cross-cultural test standardization, notably his role in translating and validating the Japanese version of the UPSIT. Dr. Matsuda also has experience in academic publishing, peer collaboration, and interdisciplinary research, contributing to joint publications with international experts. His ability to work across languages and research cultures, particularly in English and Japanese contexts, supports his ongoing success in cross-national studies.
