How to refer to an author whose last name can be confused with a pronoun? I am currently writing a research paper and am having an issue referring to an author of a paper whose name is "Dadi He". I know that it is common practice to refer to an author by their last name when referring to them or their findings. 

Though I find myself writing sentences starting along the lines of "He found that...". I assume that the simple solution is to refer to the author by his full name. But this seems to become repetitive after a few sentences.

Is this correct, is there a more formal or accepted way to do so?
Specific anti-advice (for a related situation):

If this situation arises with a female author, especially if their first name is recognizably female, I encourage you not to write out the full name each time.

It may seem unobjectionable, but this would play into the sexist practice (once widespread, though fortunately much less common today) of referring to men by last name while referring to women always by first and last name:
