Hi everyone, I'm a recent mechanical engineering graduate and am considering doing a PhD. Ideally I would like to get involved in a topic that is directly related to non-linear dynamics and chaos but am quite overwhelmed with information. I have an interest in automotive engineering as well as vibrations. To narrow my question down a bit, I'm unsure of the actual process involved in achieving this. Am I limited to advertised positions and therefore have to cross my fingers that something comes up? Or is approaching the right institution something that is an option? If anyone could provide perspective on potential topics that are related to my interests that would be great. Thanks in advance.
