<p>You really don’t need to mix it up on your engineering fields. There’s tons of crossover among engineering and hard science (chem, physics, material science) specialties. Especially at the PhD level. I suggest choosing one engineering discipline and sticking with it while finding research projects that fill your interest.</p>
<p>The one grad student I know who is doing nano device drug delivery (for cancer treatment) is actually doing his project thru the biochemistry dept. (The group is using cellular antigen markers attract the nanodevices to cancer cells. The nanodevices are actually biological, not robotic, and trick the cell into accepted a single gold atom inside the cell wall–which then poisons the individual cell.)</p>
<p>BTW, cool beans! I was looking thru Medline Plus this morning and found this:</p>
