Setting up a search in PubMed isn't difficult. However, I recommend going to the advanced search page that allows you to use search fields.
PubMed Advanced Search
- In the Advanced search, select the Author field from the dropdown menu.
- Type in the author's last name, first initial middle initial. Example: Johnston, ER
- Add this to the search with the button at the right.
- Hit search.
TIPS: The Author - Last field and the Author - First field refer to the last author and first author of an indexed work. Not the first name and last name of the author. Because PubMed indexes with first and middle initials, it's important to search on this parameter in the author field. For example: Johnston, ER instead of Johnston, Erin.

You can combine the author search with an author identifier search if you know the faculty member's ORCiD.
