Well, what I am doing now certainly doesn't qualify as a career. But, I will throw it out there since I did leave my job to do it. I worked as a design engineer near Knoxville for a few years - doing plant design and general safety/design basis calculations. I decided to leave that and head back to school to get my PhD. So, now I am finishing up my second year (of probably about five) in chemical engineering. I enjoy the program. I'm surrounded by a great group of people (my lab is great ... and most people in the department are as well). They're all a bright group, so that certainly keeps me on my toes.
As opposed to job duties, I guess that I could describe my research. I am investigating a methodology for rational catalyst design, specifically to enhance steam reformation of methane to produce hydrogen. For those of you who care...I'm performing quantum chemical calculations to investigate the surface energies of the reaction intermediates on the nickel surface. From these calculations, we have developed the first (ab initio) comprehensive mechanism to describe the reforming reaction and are almost ready to begin investigating new catalysts (nickel bimetallic alloys).
OK....no one probably cares about all that ... but, esentially I spend my days at the ol' computer performing computations. That isn't always ideal, but...it has its perks...my research is co-sponsored by Norwegian industry...so I'm going there next month, which is cool.
