Travis-CI, how to get committer_email, author_name, within after_script command

I know committer_email, author_name, and load of other variables are part of the notification event. Is it possible to get access to them in earlier events like before_script, after_script?

I would like to get access of the information and add it directly to my test results. Having build information, test result information, and github repo information in the same file would be great.
