I'm a junior at ASU, part of Barrett, and it's time to start thinking about my thesis. I am an engineering major, and I have been working at a lab for the past few years so I am planning on continuing the thesis at the same lab. My PI got me started on a project, but most of it involves trying to use this new software, and using tons of differential equations. The material is ridiculously complex, and I've spent the past few weeks trying to get better at it but I'm really struggling, and I really don't want to do this as my thesis anymore.
My PI asked me for an update tomorrow, and I don't think I should try to do a project that is this stressful because I have other responsibilities senior year that I need to keep in consideration in addition to this thesis.
Would it be unprofessional for me to speak with him about changing my thesis project? Or What should I do?
