How to get intouch with the mentor

Hello everyone am really sorry for bothering you.
I am here because I would like to get in touch with the mentor of the processing foundation for GSOC. I tried following the link with the aim of talking to the mentor but I didn’t get to him/her…
I would really appreciate if I could get help on how to reach the mentor.
And I want to also get help on how the processing foundation functions in the GSOC.
