My brother is a graduate student at the University of Tokyo.

He is a world-renowned researcher.

My laboratory is on the third floor of the university.

He is known as an excellent researcher.

I am a member of that research association.

We are focusing on the research and development of new products.

I conducted a research project as a summer vacation homework.

He lost his job, but he believes in the saying 'when one door shuts, another opens' and is looking for new opportunities.

He likes to take a walk in the park at dusk.

He is spending a lot of time on experimental research.
