Lately I have been reading about nonlinear systems and chaos. It's fascinating and I would like to know more about how I could prepare myself to possibly study this in grad school. I would be interested in looking at biological systems such as neural networks or even animal populations. I'm a biological engineering major minoring in math, but: - what extra math would I need to be prepared for graduate study? - how does research in nonlinear systems/chaos differ between disciplines (math, physics, engineering)? - is there room for bioengineers in the field or should I consider switching to something more obvious like math?
