JOIN US
Motivated and talented students, PhD students and postdocs are very welcome to join me and my new group in the quest for particles and phenomena beyond the Standard Model. Please do not hesitate to contact me if you are interested in a Bachelor, Master, PhD thesis, a postdoc or a research visit in my group.
My junior professorship started in June 2021 and I am now building a dynamic research team. Until September 2022, I will be based at CERN, and my team members can also spend a research stay or several shorter visits there before the group will move to Hannover/Braunschweig in the fall 2022.
Three PhD students started this year. Therefore, availability for additional PhD students will only start again next year. A postdoc will join the group in the fall. Bachelor and master students are welcome to join at any time.
As an alumna of the Studienstiftung des deutschen Volkes, the Minerva Foundation and the Humboldt Foundation, I will be happy to support fellowship applications of qualified candidates for these or other fellowships, e.g.
- International researchers (with a PhD or equivalent by the start of the program) are invited to apply for a Humboldt Research Fellowship of the Alexander von Humboldt Foundation for 2 years (postdocs) or up to 1.5 years (experienced researchers).
- Ukrainian researchers are very welcome to join! The Alexander von Humboldt Foundation supports researchers at risk with Philipp Schwartz Fellowships humboldt-foundation.de/en/apply/sponsorship-programmes/philipp-schwartz-initiative in Germany for 2-3 years.
- Israeli Master and PhD students as well as postdocs are in addition invited to apply for the Minerva Fellowship for up to 3 years (PhD students) or 2 years (postdocs), or a Minerva Short-Term Research Grant. !ברוכים הבאים
- Master students of all nationalities looking for PhD funding are invited to apply for a doctoral scholarship of the Studienstiftung or other suitable foundations (e.g. Begabtenförderungswerke) according to their strengths and extracurricular interests.
I explicitly welcome applications from students and scientists of all nationalities, genders and cultural backgrounds.

- 17.03.2022: Jan presented his paper on parity violation with partially stripped ions at the DPG spring meeting of atomic physics.
- 16.03.2022: I was glad to join for the first time the DPG spring meeting (even if online) of the atomic section by giving an invited talk on Searching for physics beyond the Standard Model with isotope shift spectroscopy.
- 15.03.2022: Agnese Mariotti had her first day of work as a PhD student at LUH. Benvenuta! She graduated from Università Roma Tre with a master thesis on the Dark Matter relic density in gravitational portal scenarios. Her PhD position is funded by a generous donation from the ITP alumnus Dr. Marco Krohn to the LUH-ITP. Agnese won this position through the ITP-wide selection procedure. Congratulations!
- 25.02.2022: Marco's and my paper in collaboration with colleagues from DESY, UChicago, Madrid and Paris appeared on the arXiv: Constraining the CP structure of Higgs-fermion couplings
with a global LHC fit, the electron EDM and baryogenesis. - 02.02.2022: On his second day of work, Jan's paper on Parity-Violation Studies with Partially Stripped Ions got published. Congratulations!
- 01.02.2022: Jan Richter and Marco Menen had their first working day as PhD students at the FPM (Institut für Fundamentale Physik für Metrologie) at PTB. Congratulations and welcome to the team! Jan graduated from TU Braunschweig with a master thesis at PTB on parity violation in hydrogen-like ions. Marco graduated from Uni Köln with a master thesis at Uni Bonn on the CP structure of the Higgs-fermion couplings.
- 20.01.2022: Few days before the actual start of his contract, Marco presented our work on CP violation in Yukawa couplings in the LHC Higgs cross section CP working group meeting.
- 06.01.2022: Fiona Kirk, currently PhD student at PSI/Zurich, accepted a postdoc position in our group. Looking forward to welcoming you in the fall!
- 23.11.2022: At the 14th Annual Meeting of the Helmholtz Alliance “Physics at the Terascale”, I gave a talk on constraining CP violation in the Higgs Yukawa couplings.
