Academics have little influence as to whether a person gets a full PhD scholarship: it is mostly based on GPA and publication record and is done centrally for the entire University.

It would be useful for me to know more about your background:

1. Have you published any papers before or wrote any research theses (including at undergraduate level)?
2. What relevant courses you completed in programming languages, compilers, type theory, mathematics, and do you have a transcript for that time?
3. What relevant industrial experience do you have, especially when it comes with novel programming languages and what is your interest in the area?

You can see my interests by looking at my publications.

Finally, there is much useful advice online, including this page by Michael Ernst and this how to contact potential supervisors blog post.
