Well..
I'm a Graduate Student Researcher in a veterinary genetics lab, which of course also means I'm a graduate student. Finishing my Masters this summer, as a matter of fact! Basically, I do research on naturally occurring feline genetic traits and diseases, and I oversee the health and breeding of our cat colony. My thesis is on familial aggregation of response to catnip. I also work at the Veterinary Medical Teaching Hospital at my University, as a clinical Microbiology assistant. There I set up animal clinical samples and then run various biochemical tests and immunologic assays in order to isolate and identify microorganisms that cause disease and quantify their susceptibility to various antibacterial agents.
Last but not least, I start my first year of a Doctorate of Veterinary Medicine program in a month and a half. I'll keep my job at the VMTH but won't be doing research during the school year anymore.
And for anyone who thinks grad school is putting off "the real world" or whatever...look between my index and ring fingers for my opinion on that.
