You wanted to do this:
A student fascinated with all things ancient Egyptian. Kemette squinted
at the computer screen, hoping to find the information that she
needed, to finish her research paper on
Old Kingdom art.
Adding a comma after needed is unnecessary. To finish her research paper on Old Kingdom art is an infinitive phrase. When an infinitive phrase ends a sentence, use no punctuation.
