I am an Assistant Professor in the Department of Orthoptics and Visual Sciences at Niigata University of Health and Welfare in Japan. With a background in optical science, ophthalmic dispensing, and orthoptics, my work focuses on enhancing the accessibility and quality of eye-care technologies and education. My research centers on ophthalmic instrumentation, visual-function assessment, and training methodologies for eye-care professionals. I have experience in perimetry, pediatric vision screening, and the development and evaluation of practical tools used in clinical orthoptics. I am particularly interested in designing effective educational approaches that enable trainees and non-ophthalmologists to perform reliable ocular examinations. Recently, I have emphasized the use of portable and smartphone-based technologies, including smartphone-based slit-lamp biomicroscopes, to expand access to anterior-segment evaluation in remote or resource-limited settings. I am also involved in projects on automated visual-acuity measurement using eye-tracking systems and child-friendly vision-screening tools aimed at supporting early detection of visual impairment. Through both research and teaching, I aim to bridge technological innovation and clinical practice, contributing to more inclusive, efficient, and practical ophthalmic care.
