Hey everyone !

Some of you may already know me but here’s a little introduction.
My name is Guillaume, I’m 21 and originally from Aix-en-Provence (in the south where the weather is great). I recently joined the HSE-ENV-EP team alongside Jordan regarding the noise issues for the next two years. This is the first time I got a job as I completed my studies last June at the University of Côte d’Azur in Nice. I’ve got many hobbies such as travelling, partying, meet new people or listening to music but the biggest one is definitely sports (all of them). I’m keen on doing it, watching it, talking about it… Also, spending time with family is a very important thing for me. Finally, I’m very proud to be part of your team and I’m sure this new chapter will hold amazing things. See you soon 😉
Laurent Noth

Hello! My name is Laurent Noth, 21 years old. I joined CERN in HSE-ENV-EM after completing my training as technician in industrial systems at the CPNV in Yverdon-les-Bains, Switzerland. My job is to ensure the proper functioning of the network of monitors linked to CERN’s environmental monitoring program. In my free time I like to read, ski, windsurf and play guitar. I have wanted to work at CERN since I was little, making this dream come true is incredible.
Simon Davit

My name is Simon, I’m 23 years old. I come from Farges, France, which is 15 minutes away from CERN, so I’ve always lived in the area and I know CERN since I’m a kid.
I work in the Environment group as a laboratory technician. I’m responsible to collect and analyze the water reject of CERN and his surroundings. I also help the Radio Protection for the preparation of some samples.
This is my first job after my studies but I work at CERN since 2019 but it was under another contract.
Outside of work, I love sport, my favorites are rugby, mountain biking, climbing, hiking and skiing. And I’m always listening to music.
I’m also part of an association which organized several event per year to make the village more lively since 7 years.
Thank all for the warm welcome and can’t wait to meet new people!

I will be working as a summer student in the Radiation Protection group, under the supervision of Pierre Carbonéz, on a project about radiation detection. I am really excited about working at CERN, it has always been a dream to be here, and what motivated me to pursue a career as a physicist. I hope to learn as much as possible, exchange experiences, make new connections, and make the most of this opportunity. I am passionate about nature and hiking, camping, and traveling. I also love music and cooking.

Jean-Paul Bergoeing
Hello! My name is Jean-Paul, 32 years old, half Chilean-half French (love has no frontiers!). I am a passionate geologist, interested in natural resources and the impacts of our activities on the environment. Our planet is just amazing; it provides to us everything we need. Sometimes we forget this and our desire for progress leads us to cause major problems. However, progress is needed.
Collaborating in the HSE unit represents for me a concrete opportunity to be part of the solution so that we can achieve this progress in a more sustainable way with the environment.
During my free time, I like to be in nature. I love to be in contact with rocks and vertical walls and spend time surrounded with magnificent mountains, where people become more humble. The beach and piña colada are also nice!
