I'm curious if anyone has any experience working for two advisers, particularly in two different fields. In my case, I'd focus on synthesizing materials in a chem lab (that focuses on synthesis) and then working in a EE/physics lab that would focus on characterizing said material, in particular focusing on magnetic properties. Both labs already have a standing collaboration. My skill set and interest would allow me to work in either lab. Some professors have told me to not to even bother and just be a student in one lab and work in the other lab when needed. Besides the bureaucracy of "who pays for my RA this term" and what not, what other topics should I consider?
