15 years in ATLAS

Fifteen years ago, Tuesday 8 March 2005 at 9:57am, I received my CERN account, to start working for the ATLAS Experiment.

What started as an internship – chosen because of a lack of courses in the field I originally planned to pursuit, the physics of macromolecules – in the high-energy-physics group at the Niels Bohr Institute in Copenhagen, turned into a stay at CERN during the Summer Student Programme and a Master’s thesis about the electron identification with the ATLAS transition-radiation tracker (internal) together with studies on a precision measurement of the W-boson mass.

During my PhD at Deutsches Elektronen-Synchrotron DESY in Zeuthen and Humboldt-Universität zu Berlin and various short stays at CERN I was mainly working on the commissioning of the ATLAS pixel detector (internal) and data-driven algorithms to determine the W+Jets background in events with pair-produced top quarks, and was involved in the startup of the German National Analysis Facility.

Going back to the Niels Bohr Institute as a postdoc, I started working on searches for unconventional signatures and long-lived particles and got stuck with that ever since.

I started out looking for heavy, charged long-lived particles, an analysis I continued also after moving to LMU Munich in 2014.  Since then, I had the pleasure of leading two ATLAS physics subgroups – supersymmetry with R-parity-violating and long-lived signatures as well as exotics with unconventional and exotic Higgs decays – and joined a community effort in documenting the current status and harmonise searches for long-lived particles at the LHC. Amongst other things, I am currently also working on searches for Soft Unclustered Energy Patterns as signatures of strongly coupled Hidden Sectors and just finished my habilitation.

Besides physics analysis, especially looking for long-lived particles, I was always interested in science communication and education and have been involved in outreach projects since 2006. Highlights were and are certainly the design of the ATLAS LEGO model in 2011, the creation of the ‘Build Your Own Particle Detector‘ programme in 2013 and running it since, the coordination of the ATLAS contribution to the 2019 CERN Open Days, and the still ongoing work on a new ATLAS Visitor Centre. Since 2018, I am also an Education & Outreach coordinator for the ATLAS Collaboration.

I hope to have quite a few more years within ATLAS and other collaborations …

Honour & Glory

This  year’s UEFA European Championship is finally over … and … we have a winner!

Congratulations to Lea for a fabulous victory!

Congratulations also to Bernd K. and Janine for the ranks, especially to Janine who was in the lead for almost half of the championship. I can only repeat what I already said after the group stage: quite an impressive show by some of you.

Down below is the final overview on player points/ranks.
As usual, you find all the details (schedulestandingsmatchboards, yes there’s multiple; scoreboard; and alternative counting) in the Honour & Glory section.


Honour & Glory

It’s time for this year’s (major) Honour & Glory event – EURO2016 is starting in a few days!

Remember to check your account and place your bets before the matches start!
The bets and some stats and plots will be visible right after kickoff and I’ll do my best to put in results quickly.

Looking forwards to another exiting (betting) event!
Let’s see who’s going to make this time … newbee or someone with history ;)

Collider Paris inauguration

As the Atlas Lego model will be an official part of the Collider exhibition in Paris, due to open in November I received an official invitation to the inauguration party :)

Unfortunately it seems I wont find the money to actually go there :)

Anyways, it’s great to see the Atlas Lego model being an official part of this exhibition.
