Once she has a base understanding she might look at getting an internship to learn the ropes, if she isn't tied to a job right now or needs good income immediately.
I've been involved with teaching girls to code so the above comes from experience.
I was in college, getting a Bachelor's degree in Psychology, and was invited to a grad level class on item response theory. We were using R, and had to analyze 2400 items, and each was taking 3 - 6 minutes because of the function. That would be 5 -10 days if we did them all, and people were cutting it down to 50 item problem sets and emailing the teacher, and trading sets of items back and forth, and still running computers for a long time.
I figured out how to optimize the algorithm so that each took a few seconds, by coming up with a very naive version of something like a binary search. Having it be an order of magnitude faster was cool, but coming up with the idea myself was what made me interested in CS.
