Coming into vet school, my research experience was, well...more chemistry than anything else.
I worked summers and breaks for three years in high school and college (full-time, so it racked up a load of hours) at the Naval Research Lab in Washington DC, studying cytochrome-c interactions when incorporated into silica aerogels...basically how the proteins would form a "buckyball" like structure around a metal nanoparticle core, and how the outer "shell" or protein would "protect" the inside of the ball when exposed to insulting substances.....wohoo electrochem and nanotechnology! Got a nice publication out of it, too. Then I spent a summer at a conservation lab doing biochemical analyses on protein, carb, and lipid components of mussel tissue (as in severly endangered freshwater mussels) - basically to see how they were doing in relation to water quality, etc.
Summer after my first year at vet school I did a pathology externship at Wake Forest's Primate Center doing reproductive histopath, attending rounds, working on RNA research....one of the coolest experiences of my life. I highly recommend it to anyone interested in pathology!! They are always interested in having people come down.
