Examining how nanosensors can monitor the build up of harmful bacteria
I’m really passionate about microbiology because bacteria are just as complex as other animals and organisms. People assume bacteria are simple single cells, but studying them can really benefit human health and biology. There is so much to discover about bacteria – I find that quite exciting.
My project focuses on complex bacterial communities encased within matrices, which are known as biofilms. These biofilms can build up inside washing machines and cause human infections. Nanosensors have been developed that can monitor molecules in contact with the individual bacterial cells, and tell us how these communities of bacteria are formed and survive in situ. The data we collect can then help us to formulate more effective ways of eliminating harmful microorganisms in household appliances.
I chose to do my PhD at Nottingham because I did my masters here, so I knew that the University had a really good research reputation and great facilities. My route into research started with a general biology undergraduate degree, where I discovered my interest in microbiology, and so came to Nottingham to do a masters degree in clinical microbiology. I wanted to explore microbiology further and I thought a PhD would be the best way to do this.

The doctoral training programme at Nottingham is great because it gives you the chance to try out lots of different lab rotations and work environments right from the start. I have had many opportunities to present at conferences and build a network of contacts. The thought of presenting at STEM for Britain in Parliament was quite intimidating at first since I was presenting to experts in my field. But once you do it you realise it’s not scary, but actually a great opportunity. It really helps to build up your confidence.
The training that comes as part of your PhD helps you to develop presentation skills and encourages you to take more opportunities. The annual conferences are a fun time to meet with peers and learn new skills together. In addition, the professional internship placement gave me the chance to train in another lab for three months. This helped me to broaden my skill set and think about what I want to do after finishing the programme. I was even offered a job as a result of my placement.
I’ve felt really welcomed – particularly for people who came from different cities, it was nice to establish a group of friends at the start.
There was a great support team and the option for financial support going into my placement. I am lucky in that I haven't needed too much extra support, but I know that I can always go to the team if I need help with anything. The fact that you enter the training programme as a group means you can build your own support network from the start. You become part of a community. I’m living with two people that I wouldn't have met if we hadn't all decided to do our PhDs on the same doctoral training programme.
