About Me:
Hi! I’m Sinead, and I’m a particle physicist who currently lives in Geneva, Switzerland🇨🇭. During the week, I spend my time studying data, but on weekends, you’ll find me watching true crime shows or spending time with the local cats! 🐈

On weekends, I like to stay active, so I often go shopping or for walks with my partner. We’re lucky to live near lots of farmland, so we get to enjoy beautiful walks—and often meet the local cats along the way! I love animals, so whenever I can, I visit farms or petting zoos. Sometimes, I even get to visit my partner’s family dog, which is always a treat!
I’m not someone who likes to sit still, so I usually keep myself busy with a few things at once. In the evenings, I like to wind down by watching my latest TV show (right now, it’s Grey’s Anatomy) while doing some drawing on my iPad. Having this time to myself is a great way to relax after a long day.

My Work:
I study tiny particles that make up everything in the universe. These particles existed just after the Big Bang, and by studying them, we can learn about the early universe. I work on an experiment called FASER at CERN. My research focuses on finding special particles like neutrinos (which are almost invisible) or other particles that might help us understand dark matter.

The Large Hadron Collider (LHC) is the biggest machine in the world for smashing tiny particles together. These particles, called hadrons, crash into each other at almost the speed of light. By studying what happens in these collisions, we can learn more about the universe.
I work on an experiment called FASER, which is in a tunnel under the LHC. Our detector looks for particles that other experiments, like ATLAS, might miss. There is 500 meters of rock between ATLAS and FASER, which helps block unwanted signals, making our results clearer.
Because the detector is underground and becomes highly radioactive when the LHC is running, we control it from a distance using computers. This is one of the coolest parts of my job! I get to take turns running the detector from my laptop for a whole week when I’m on shift.
After we collect data, my team works on analyzing it. This process takes about a year because there is so much information to go through! We first decide which particle we want to study—sometimes one that might interact with dark matter. Then, we use computer simulations to plan our analysis. Once we have results, we share them with other scientists at conferences and publish them in papers.

My Typical Day:
I wake up early (or at least it feels early!) at around 7:30. I start my day with a bowl of porridge and a cup of tea before heading to my office at CERN. I usually arrive around 9 AM and begin by running some code to analyze data.
I always take a nice long break for lunch and eat in the canteen with friends. In the afternoon, I either have meetings or do outreach work, and any extra time is spent on more data analysis. By 6 PM, I finish up and head home for the evening.

I like to start my day by writing a to-do list on my iPad—it helps me stay on track since I can easily get sidetracked! When I get to the office, I check my calendar for any meetings. If I’m on shift, I also check what tests need to be done on the detector and might have meetings about this.
Every day includes some data analysis, which means coding and making graphs. I really enjoy coding—seeing the little blue squares light up when I update my code on GitLab is a great motivator! When I finish a piece of code that produces a useful graph, I send it to my supervisors so we can discuss it. Research is all about teamwork, so this is an important part of my day.
Some days, I also give tours at CERN, which is one of my favorite things to do! Recently, I’ve taken groups down to see the ATLAS detector and explained how it works. I love answering questions about physics and detectors.
At the end of the day, I write down notes about things I want to work on tomorrow—ideas to explore or changes to make in my code. This helps me remember what to focus on next!

What I'd do with the prize money:
I want to challenge the “one size fits all” attitude that persists in STEM. As an AuDHD female physicist, I know firsthand that there isn’t just one way to think, learn, or solve problems. Diverse brains and backgrounds don’t just belong in STEM—they make research stronger.
Studies show that lack of representation can make it harder for young people to see themselves in certain careers, leading them to feel like they don’t belong. That’s why I would use the prize money to organize school visits, particularly in schools with lower STEM progression, to showcase the real people behind scientific discoveries.
These sessions wouldn’t be the usual career talks—they would focus on the role of failure in STEM and how mistakes often lead to breakthroughs. They would highlight the many different ways to approach problems, moving beyond traditional classroom methods. Through interactive workshops, students would explore alternative ways of thinking, learning, and problem-solving—helping them build confidence in their own unique approaches. A goal of these session would be to come up with a list of ideas for alternative ways to learn concepts – perhaps trying out one to learn a simple concept. This would make a hopefully memorable session for the students.
A core part of these sessions would be fostering open communication—emphasizing that there is no such thing as a stupid question and encouraging students to ask, experiment, and embrace failure as part of the learning process.
