$$ The first step of creating data models is to identify the entities. In this scenario there will be three entities: Institution, Researcher, and Research Interests.

$$ The next step is to identify attributes for each entity and assign identifiers. For example, attributes about Institution will include university name, location, enrollment. I would select university name as an identifier as that should be a unique attribute for each record in that table. You will need to determine the attributes and an identifier for Researcher and Research Interests entities. Remember that an identifier can consist of a created id field if you do not have an attribute that is unique for that entity.

$$ Last step is to identify relationships between the entities. You will have a relationship between Institution and Researcher $($remember they go both ways so you will also have to establish$/$define the relationship between Researcher and Institution$),$ and another relationship between Researcher and Research Interest $($and vice versa$).$ Please make sure to specify the cardinality for each side of the relationship in your model.
