You're absolutely right. It should read:

My cousin, who is a research chemist, works in the food industry.

Thanks. Could you please give me a reason?

Thanks. Could you please give me a reason?

Because when you are referring to a human being, you use who. When referring to an animal or an inanimate object, you use which.

My brother, who is very tall, is a basketball player.
My boss, who is very rich, has a big house.
Your uncle, who has grey hair, has blue eyes.

The cat, which is black and white, has fish for breakfast.
The table, which only has 3 legs, falls over very easily.
The candles, which smell of vanilla, are on the mantelpiece.

Thanks.
But where is that ?

That can be used with people and things.Why can't we use it here?
