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 acted according to my instructions one by one.

His advice was very practical.

His target-like way of thinking is hard to understand.

He is my biggest enemy.
