Jobs und Abschlussarbei­ten

Alle offenen Postdoc- und Doktorandenstellen in der Gruppe werden auf Inspire veröffentlicht. Darüber hinausgehend freuen wir uns über Deine E-Mail, falls Du an Themen arbeiten möchtest, die in das Profil der Gruppe passen.

Falls Du als Student gern Deine Bachelor- oder Master-Arbeit mit einem Projekt in unserer Gruppe durchführen möchtest, dann kontaktiere Frank Siegert, um potentielle Themen zu besprechen. Da die Gruppe an der Schnittstelle zwischen Experiment und Theorie (der Teilchenphysik) arbeitet, steht ein breites Spektrum an Themen zur Verfügung, sei es in Verbindung mit Messungen des ATLAS-Detektors am CERN, oder Theoriesimulationen für solche Messungen, oder sogar technischere Aspekte über Monte-Carlo-Methoden.

Für Bachelor/Master-Studenten: Folien Informationsveran­staltung Januar 2021
