Favourite thing to do in science: My favourite thing about science is learning new things. The way for me to learn new things is to carry out experiments! For my PhD I have to carry out lots of experiments to try and understand what is happening, and so every day is great fun! Scientific outreach activities are also great fun because I get to show people cool and interesting things, plus I like being able to inspire people! Science is all around us so why not try and learn something new everyday?
I am inquisitive, ready for adventure and I love doing new wonderful things!
I live with my mum, dad and my brother at home. I have many interests such as gaming, reading, anime, travelling, scuba diving and fencing. I love to travel around the world, and I have been to exotic places. In fact I plan to visit my friend who lives in Japan in 2017. While I travel I like to go scuba diving as well because the underwater world is pretty amazing and unique!
Fencing is great fun as I get to play with swords and fight people with them! There is a lot of skill required for fencing but if you ever get a chance to try it then do! I absolutely love it! I have done archery in college as well, but I have a few more things I have yet to try, such as skydiving and bungee jumping…. I do hope that I get a chance to try skydiving at some point, maybe before I finish my PhD?! I would try anything once, and that applies to food too as I have had some unusual dishes such as reindeer, frogs legs, pigs tail, camel, crickets, cactus, crocodile and kangaroo!
I love learning new languages as well. I learned German and sign language when I was in secondary school, but I could be a bit rusty now.. I work with people from all around the world and I’m slowly starting to learn other languages such as Swedish, Italian and Japanese! Someday I hope to live and work abroad so hopefully one of those languages will help me!
Of course I love science.. otherwise I wouldn’t be here today. I fell in love with it when I was young, and I had a chemistry kit which to me was amazing! When I got to secondary school I did both biology and chemistry, and I loved every moment of it. Even in college I loved doing science, but chose chemistry over biology because I wanted to chase my dream of doing forensic science and chemistry. Currently, I am doing an electrochemistry (chemistry that requires electricity for reactions to occur) PhD, and I couldn’t be happier!
On top of my PhD research, I also carry out outreach activities where I basically get to talk about science and energy, while demonstrating experiments with really cool gadgets. One example of some cool gadgets that I get to use is a car that uses hydrogen gas from water to drive, that’s my favourite piece of kit and it really demonstrates how beneficial science is to society.
I have given public talks at science festivals, during energy week, and other fun venues. At these kids have come up to me saying that they want to be a scientist just like me when they grow up and nothing is more rewarding than hearing that you are an inspiration.
If you have a thirst for knowledge, a drive to overcome challenges and enjoy science then join a STEM career path… you won’t regret it!
I have to design and build a teeny tiny battery (1mm or smaller) that can be very powerful, environmentally friendly and safe.
My PhD is funded by Science Foundation Ireland’s CONNECT centre, which means they are paying me to carry out research for them. They want research into the Internet of Things (IoT) to be carried out all across Ireland, and I was lucky enough to work in this wonderful centre. So what is the Internet of Things (IoT)?
Well….the IoT connects dumb devices like refrigerators to the internet and uses software to connect them to our daily lives. Can a car talk to a house? In the future, your car might tell your house that you are a few miles away and ask the house to turn on the lights and heating. This would mean that your home is nice and toasty when you arrive, which would be pretty cool! This is one example of an idea called the IoT. So the IoT, connects dumb objects such as refrigerators, washing machines, cars, etc to the internet using software, sensors and WiFi. Sounds pretty cool doesn’t it? If you have any questions about this, please ask away… I’m still dreaming up possibilities for the Internet of Things!
In order for sensors to work they need power, and this is where my PhD comes into it. I am looking to design and build a battery which is very powerful, environmentally friendly and safe to use (I do not want any of my batteries exploding!). The batteries that I will be making are small, so I hope to have them even smaller in size than 1 millimetre, which will be a tough but rewarding challenge!
My Typical Day
Carrying out experiments in a glovebox, and then analysing the data. Once I look at the data, I make a presentation with all my data, and send it on to my boss for discussion.
As I must design and build a battery I have to use lots of different chemicals and materials. In order to carry out my research I have to make up an electrochemical cell which generally consists of:
1. Two or three electrodes
2. Electrolyte (generally a liquid)
I pass electricity through the electrodes which allows chemical reactions to occur. The reactions that I get depend on the electrolyte I am using and the electrode material. I am currently carrying out research on the electrolyte, which is the liquid part of the battery, which means I only have to use a metal such as lithium metal for my electrodes.
Lithium metal reacts violently and explosively with water and so I have to use a glovebox. A glove box contains only argon gas, so there is no chance that water can sneak in and make my electrodes explode! Once I construct my electrodes, I place them in a container which contains my liquid electrolyte, and I seal it tightly to stop the cell from leaking. Once that is made, I then connect everything up to a machine called a potentiostat, and using this machine I can apply different voltages, currents and techniques and this will give me different data.
Once I have the data, I then sit at a computer and make graphs. I then have to figure out what they mean by reading papers, and once I know what the results mean I send on the information to my boss. He looks over it to see if what I said is correct, and we then talk about it, and see what else can be tested. Everyday I am trying something different so each day is a new adventure! It never gets boring!
What I'd do with the money
I would buy some cool battery demo kits to go with my fuel cell car kit, and if I have money left over I will donate it to Tyndall’s Makerspace so more outreach activities can be carried out.
My lab already owns a fuel cell car kit which requires hydrogen gas from water to run, which is pretty cool. If I win, I would be using the money to buy a cool battery demo kit because batteries are just as cool as fuel cells. This is something I would like to show people, because a friend once told me before that batteries are boring… Of course I was shocked by that! So the money would be well spent buying a cool demo kit, as I would like to use the kit to encourage kids to look into batteries and maybe find a career with them some day!
If I happen to buy a kit and have money left over, then I will donate the remaining money to the Tyndall Makerspace. The Makerspace organises a lot of outreach activities, some which I have been proud to take part in. It encourages people to be inventive and to think outside the box. It helps unleash your creative spirit which I think is important too!

A chemist, or a forensic scientist
Were you ever in trouble at school?
I was never in trouble really..
What was your favourite subject at school?
Chemistry and Biology (Couldn’t pick!)

What or who inspired you to become a scientist?
My gran initially who bought me my first ever chemistry set, and then my chemistry teacher when I went to secondary school
If you weren't a scientist, what would you be?
I always wanted to be a Formula one driver… or a rally driver. Both seem pretty cool.
If you had 3 wishes for yourself what would they be? - be honest!
I would wish for 1) a genie so I can get more wishes, 2) for cool outreach demo kits, and 3) I would want to be a famous scientist!
Tell us a joke.
Don’t trust atoms… they make up everything!
I work in a clean room lab, and this means that we have make sure that we don’t bring any dirt or dust into the lab. so we wear hair nets and booties. We must also wear our lab coats and safety glasses so we can avoid getting injured in the lab. I also have to “wear” the glovebox gloves as I wouldn’t be able to use the glovebox without them!
