You must be the guy who posted the "Majors" thread.
A little EE knowledge is helpful to know what kind of stuff will eventually be needed from this technology (logic gates, half adders, etc). Advanced EE is all about semiconductor transistors, and will be outdated by the time this technology is mature anyway.
Physicist? maybe, but biotech is probably a better choice. If you do attempt physics, this probably falls under biophysics, and maybe a little under condensed matter too.
