It's a lab technician job for one of the labs at Vanderbilt med school.
The lab tech is pretty much responsible for everything that goes on in the lab. That includes purchasing materials, equipment, and supplies, writing grants and research articles, developing experiments and protocols, training other people who join the lab, and basically maintaining everything in the lab. Being in a biology lab, that can include viruses, bacteria, animals, etc.
This lab does research on a condition called atherosclerosis, which is a hardening of the arteries caused by cholesterol accumulation. The lab I may end up in used to do research using mice, but has since moved on to "cell culture."
When I tell people I use "cell cultures" many people don't understand what I'm talking about, so I'll elaborate. Doing research on animals is a very expensive and complicated endeavor, and they're not practical when you're only interested in doing research on a particular area of that animal, say the kidneys or the heart, or if you're interested in researching abnormal cells, such as cancerous cells (also radical animal rights groups don't like it, and try to sabotage our labs, or in very rare circumstances, assault or murder the researchers).
Instead, scientists collect a sample of cells from the part of the body of an animal we are interested in, and we attempt to grow those cells independently of the animal we collected them from by putting them in a sterile container and providing them with a liquid media, basically food that is specially made for those particular kind of cells.
Some cell cultures may only last for a few weeks before they lose their ability to grow, we call these "primary cell lines", because they came straight out of a living organism. However, there are others that are called "immortalized" cell cultures. These are cells that are able to grow nearly indefinitely such as stem cells, cancer cells, and various other cells that naturally grow and divide. These cell cultures can last for decades, so they get special names and designations, so when a scientist receives some of these cells, they will know what specific animal and organ they came from, who started the culture, when it was started, and how they generally behave. To give you an idea of how long these cells can persist, I have worked with a cell line of human cervical cancer cells, called
HeLa. The original line was started using cells taken from a biopsy of a woman named "Henrietta Lacks" sometime in the late 1940's. Ever since the first cells started growing, they've been living on a steady diet of cell media for almost 60 years.
Anyway, scientists often do research on cell lines first, especially when developing various treatments or pharmaceuticals. When we discover something that works in the cell lines, then we move to testing on whole animals, usually mice. If it works in mice, then it goes through testing in several other animal models (monkeys, cows, dogs, etc.) and finally, if it passes muster there, whatever drug or treatment may be tested on humans.
The lab I may be working in doesn't develop treatments or drugs or anything like that; it's focused on finding the underlying nature of the disease they're researching. Based on the discoveries made in that lab, others may take the results and apply them to new therapies and treatments.
EDIT: Next time you're watching the news or a TV show talking about biology stuff, and you see a clip of a researcher putting a pink liquid into a large, clear plastic container like a petri dish or a flask, chances are, they're showing you a video of someone who is in the process of feeding cells. It's the cellular version of sprinkling fish flakes in an aquarium.
This is such a sadtea moment.
