I work on the advanced composites in the department of Aerospace. you know, materials preparation, property characterization, analysis of microstructure. I spent my last three years doing nano-materials, but now i do composites. a new field, but because it's related to spacecrafts. i think it's more of engineering than science. i think this degree just involves a lot of experiments. no deep theory is needed. i find that engineering is more useful,but science is more interesting to me. kind of crazy,aint i. . i know social life is important too. i hope i could make friends with you guys. big phd family. hehe.
