Eliana Rodriguez, who teaches Biology, is my favorite teacher because she gives engaging lectures.
The subordinate clause, in this case "who teaches Biology" should go between comas. This subordinate clause is used to specify or give additional information about the subject.
Here are some examples:
- Christina, my best-friend, loves apples.
- Paris, which is in France, is one of the world's most famous touristic destinations.
- Elizabeth, my mother, loves to bake cookies during Christmas.
