About Me:
I live near Cardiff, I speak French and I love to climb! I decode DNA for a living. But I also go climbing indoors every week and love to climb outside in the summer. I always want to travel and been to many countries like Japan, Canada, Hungary, Costa Rica and Croatia.

I come from a small village in the Rhymney valley. In school, I learned how to play the clarinet and later the tenor saxophone. When I got older, I learned how to play bass guitar and acoustic guitar and played in a band for a short while. I finished comprehensive school with good grades in the sciences. So I went straight into college to learn Biology, Chemistry, Physics and Psychology. But I hated Physics! So I swapped Physics for Electronics which was a bit more interesting.
I took a gap year after college. I wasn’t sure what I wanted to do. I liked working in the lab, so I decided to do a lab-style degree. I moved to Cardiff to a degree in Biomedical Science. I enjoyed living in Cardiff so much, that after I finished university, I decided to stay.
With a bit more time and money, I was able to learn how to climb. I made good friends at the climbing centre and I still meet up with them every week.
When I started climbing, I was capable of some easy routes (5, 5+ or V2) but I’m proud to have improved a lot. I’m now climbing hard routes (6b, 6b+ or V6) which makes climbing much more challenging!

How I use Science in my work:
I use machines called sequencers to read your DNA. Reading your DNA tells us about how your body works and what makes you different. It can also tell us why you might be ill or have different needs to other people.
-
My Work:
I am a scientist in genetics. My job is to decode your DNA. Your DNA can tell us all about your health. I tell doctors how to help people who have diseases in their DNA.

I work in a genetics lab. In this lab, our goal is to understand why someone is sick. It could be that this person has been seen by their doctor. This person might have already had tests that didn’t tell them very much about why they are sick.
We will take a sample of blood and perform some lab techniques (experiments) and we will eventually put this sample into an analyser (a machine that can read something in the sample). This analyser will give us data, and with this data, we can make a diagnosis. A diagnosis is another way of saying that you can prove that someone has a specific disease. A good example of an analyser is a DNA sequencer, which can read your DNA like a book.
Most of the diseases we test for can be divided into two categories:
- Hereditary Diseases
- Cancer
If you have a ‘Hereditary’ disease, then your mum or dad might also have the disease. Just like you might inherit blue eyes from mum or brown hair from dad. You can inherit a disease the same way. A classic example is something called mitochondrial deafness. People with this disease cannot hear from birth. Mothers with this disease will always pass this disease to their children. But it is unfair for us to call mitochondrial deafness a disease. The deaf community is a rich and communal culture. Most people who have mitochondrial deafness it see it as a part of their identity.
You will likely have heard of cancer before. What most people don’t realise, is that cancer is a genetic disease. Normal cells turn into cancer because of changes in their DNA. Testing the DNA of cancer cells can tell us loads about what sort of cancer it is. We can learn about how it behaves (if it is fast growing or slow growing). But more importantly, we can learn about what drugs would be best to fight it.

My Typical Day:
My work day starts at 8am. I check on all of the experiments that were running on machines overnight to see if they worked. I’ll also check all our fridges, freezers and our liquid nitrogen storage tanks to make sure they are nice and cold and nobody has left them open! In the afternoon I will spend my time helping my scientists prepare the new experiments. I make sure they are working carefully and don’t drop anything that could burn a hole in the floor. Then I’ll go home at 5pm.

The experiments we run are actually tests for diseases. They
