Healthy aging brings well-being in older people. New medical methodologies contribute longer life expectancy, however, most of older people are likely to have health problems, especially in musculoskeletal system, vision and brain functions, over a certain age because of lots of complicated factors like lifestyles, food digestions, and genes. It could worse for people living with disabilities. To have older life with health problems better for all in any situations, Dr Tatsuto Suzuki mainly focuses on investigating what people living with disability can comfortably do in their daily life at home and public transport, and if not how difficult it is. He also focuses on how make the life of people living with disability better, with adapting environment and assistive technology to individual capabilities.

Dr Tatsuto Suzuki conducts his research at the Person-Environment-Activity Research Laboratory (PEARL, UCL) started in 2021. PEARL is a unique facility to explore the ways in which people interact with their environment, and can change the profile, type and material of the physical environment, including the ground, simulate lighting of any colour and intensity (PEARL is the only facility in the world that can match environmental lighting to the sensitivity of the human eye in both intensity and colour), create and manipulate ambient and specific sounds, include controlled olfaction sensations, and set up any type of real size life environments. PEARL enables us to study in detail how people actually interact with the environment and each other, by enabling us to test detailed differences in the environment, so that we can obtain rich data for use in the design of real environments for individual cases.

Dr Tatsuto Suzuki's research interests are;

- Investigation of basic behaviour and comfort of daily activities for people in aged or living with disability

- Improvement and development of environment and assistive technology for individual capability.

- Evaluation and improvement of wheelchairs and other personal mobilities.

- Locomotion with multisensorial activities

- Biomechanics

- Control and measurement systems

- Mechanism

- Health and safety
