Excellent perspective, as always.
I think she will carve out some time in the summer and perhaps during the in-school semesters to do an internship or two in the field (paid or unpaid) and also volunteer and/or participate in TA/research opportunities as they present themselves. She may not get into a GC program right away, as you mention, but she will have an opportunity to get some work/life experience (UA has some great student volunteer organizations in this respect as well).
I think the skill set she will build over this time will be very valuable and provide a lot of optionality. She will have an opportunity to network and meet a lot of very diverse individuals in her studies (students, professors, employers, mentors). That’s all I could hope for at this point. The rest is up to her. She needs to be proactive and opportunistic in pursuing what interests her most.
Really want to thank you again for your insights. So appreciated!
