Circular Design Engineer

About

Keita Sekijima obtained a master’s degree in design engineering from Keio University in 2016. Since then, he has been working for Sony, where he began his career in April 2016. From 2018 to 2023, he focused on developing user experiences for audio products. Most recently, From August 2023 to August 2024, he served as a visiting researcher at Delft University of Technology, where he explored design for a circular economy. His current interests lie in circular design and circularity assessment for consumer electronics.
