Profile

I’m a microbiologist and that means I work with micro-organisms. Micro-organisms are living things that are so small you need a microscope to see them like viruses, bacteria and some fungi and parasites.

A clinical or medical microbiologist like me works with micro-organisms that can cause disease and make humans ill. The hospital laboratory where I work gets hundreds of samples from people with infections every day. The samples get taken by doctors and nurses and get sent to our laboratory. We get urine, poo, sputum (spit), skin swabs, nose and throat swabs, blood samples, pus, bits that surgeons have cut off and a whole lot more. It can be quite disgusting but it’s always interesting.

Once we get the samples we test them depending on what they are and what the doctor thinks is wrong with the patient. We have lots of different ways of finding micro-organisms in the samples: we can look at the sample down a microscope, we can grow bacteria or fungi on agar plates or, if the micro-organisms won’t grow on agar plates we can find their DNA and tell what they are.

Once we know what micro-organisms are in a patent’s sample we can find out what antibiotics or other drugs will help kill them and cure the patient.

My work is mainly to help design new tests so we can find more disease causing organisms, find them faster, find them more accurately or tell more information about them.

There are lots of different things I do during the day.

At the start of a new project I spend a lot of time finding out background information. I go to scientific conferences to see what other scientists are doing round the world, I read scientific papers and sometimes I just “google” to find out what’s out there on the internet.

Some days I get my white coat on and work in the laboratory doing experiments. I’ll be trying new things to see what works best.  I also spend a lot of time in the lab when I have a new test method working but need to test it against lots of samples. We have to be really careful that we are 100% sure the results of the tests we do are correct because people’s lives might depend on them.

After I’ve done the lab work, I spend time writing. Scientists have to write up everything they do so that other people can understand what they did and why. If the results are really important I will try and get them published in a scientific journal so other scientists from all over the world know about my work.

On most days I end up giving expert advice. I work with the biomedical scientists who carry out the tests I have designed so if anything goes wrong we can work out the problem and fix it together. I also talk to doctors and nurses to explain the tests we do so they can send us the right samples from patients at the right time.
