Admir Greljo

The University of Basel is offering two postdoctoral research positions in the Theoretical Particle Physics and Cosmology group led by Prof. Admir Greljo. The group explores fundamental physics beyond the Standard Model, with research spanning three closely connected areas: flavor as an organizing principle beyond the Standard Model, precision probes at present and future experiments, and particle cosmology as a probe of fundamental interactions. In the flavor direction, the research touches on the origin of fermion masses and mixings, flavor symmetries, BSM model building, and implications for flavor, CP, and collider observables. The precision program includes effective field theory, SMEFT, electroweak and flavor precision physics, collider phenomenology, and opportunities at the LHC, FCC-ee, and high-intensity experiments. The cosmology direction covers dark matter and dark sectors, axions and ALPs, baryogenesis and leptogenesis, dark energy, cosmological phase transitions, and gravitational waves. Successful candidates will join a collaborative group of postdoctoral researchers and PhD students, with room to develop independent research ideas, initiate collaborations, and pursue both individual and joint projects. The positions are supported by the Swiss National Science Foundation project Probing the Origin of Flavor with Colliders and Gravitational Waves , and the group is also involved in CHEF – Swiss High Energy Physics for the FCC, connecting the project to the broader Swiss particle-physics community and CERN. The appointments are for two years initially, with the possibility of a third year depending on performance and funding availability.
