I think there's a whole world out there, you know, at the nanoscale. A wise man said, just because we couldn't see it all this time doesn't mean we just invented it! We can learn a thing or two from natural nanomachines that keep us running so well (enzymes and genes and proteins and all those little molecules that are more sure of their lives than we are of anything!) and make some of our own! And the best part is the most malleable and programmable building material given to us - DNA!
So I am a nanoengineer and I have to refrigerate all my power tools.
I am also a graduate student at Iowa State University in Bioinformatics. But in truth I am an interdisciplinary researcher.
