I got accepted into a PhD program this Friday! I am both very excited and nervous for this opportunity. I received a RA (19 grand for 9 months and an additional 6 grand for over the summer, totally 25 grand/yr), which states that I will be working on stochastic stability and control of drones/UAVs. This will be in the mechanical engineering department and should be a very interesting topic as it combines aircraft design, mathematical modelling, and fluid mechanics. Now that I have an offer with money, do you guys have any recommendations for questions I should ask? I have a few in mind, but I have been communicating back and fourth with the university for some time now.
