Join Us
We welcome motivated Ph.D. candidates interested in theoretical particle physics and astrophysics. If you are considering joining our group, I encourage you to first explore our research and get to know the group through an exchange visit, for example through the CSCI Inbound Summer Exchange Programme. Please consult the programme page for eligibility requirements and application details. Applications for Ph.D. positions should be submitted through Academic Jobs Online.
