Andreas Crivellin
Name	Andreas Crivellin

Andreas Crivellin is a physicist and scholar known for work at the intersection of theoretical particle physics, flavor phenomenology, and beyond-Standard-Model model building. He has contributed to analyses of flavor-changing processes, lepton-flavor violation, and precision tests of the Standard Model through effective field theory techniques. His research spans collaborations with experimental groups and theoretical consortia across Europe and North America.

Early life and education

Crivellin was born and raised in Europe and completed secondary education before entering university studies in physics and mathematics at institutions connected with ETH Zurich, University of Zurich, and comparable centers for physical sciences. He pursued graduate studies that led to a doctoral degree (PhD) under supervision linking research groups associated with CERN and national research institutes such as INFN branches. During his doctoral formation he interacted with researchers affiliated with Max Planck Institute for Physics, Institut de Physique Théorique, and fellowship networks connected to European Research Council programs.

His postdoctoral training included appointments at major theoretical hubs, integrating methods developed in collaborations with investigators at DESY, SLAC National Accelerator Laboratory, and groups associated with Fermilab and KEK. This period broadened his exposure to precision flavor observables studied by experimental collaborations such as LHCb, ATLAS, and CMS and to theoretical frameworks propagated in venues like Les Houches workshops and seminars at Perimeter Institute.

Research career

Crivellin’s research career has been anchored in theoretical particle physics with emphases on flavor physics, effective field theory, and new physics model building. He has held academic and research positions at institutions including universities and laboratories linked to CERN, Paul Scherrer Institute, University of Liverpool, and other European physics departments. His agenda integrated phenomenological studies relevant for experiments at Large Hadron Collider, flavor factories such as BaBar and Belle II, and neutrino experiments like T2K and NOvA.

Throughout his career he has contributed to global fits to flavor observables, coordinating analyses that interface with experimental results from LHCb, Belle, and low-energy experiments such as MEG and Mu2e. He has produced computations using tools common in the community developed in conjunction with teams at HEPfit and initiatives linked to Flavour Lattice Averaging Group activities. His trajectory includes invitations to workshops at KITP, presentations at ICHEP and Moriond, and roles in collaborative projects funded by European Commission and national funding agencies.

Major contributions and notable publications

Crivellin is best known for contributions to theories of flavor anomalies and precision probes of lepton-flavor universality. He has published influential papers analyzing deviations in observables measured by LHCb such as ratios involving B meson decays, and has proposed model explanations invoking extensions related to Z' boson scenarios, leptoquarks inspired by grand-unified frameworks like SU(5), and radiative mechanisms reminiscent of constructions studied in contexts of Minimal Supersymmetric Standard Model and two-Higgs-doublet models explored by groups at CERN and DESY.

His work includes calculations of loop-induced processes, operator analyses within the language of Standard Model Effective Field Theory, and detailed studies of constraints from electroweak precision data gathered at LEP and from flavor constraints established by Belle II. Notable publications span journals and proceedings where he co-authored papers with scientists affiliated with MPIK, University of Zurich, University of Bonn, and other centers. He has contributed to review articles on flavor physics cited by collaborations conducting global fits and by theorists at IPPP and IFAE.

Awards and honors

Crivellin’s work has been recognized by invitations to prestigious lecture series and by competitive fellowships and grants. He has received funding through programs administered by European Research Council and national science foundations, and has been awarded fellowships associated with institutes like Erwin Schrödinger International Institute and guest scientist positions at CERN Theory and Max Planck Society institutes. His papers have been highlighted in community reviews prepared for conferences such as ICHEP and EPS-HEP.

Professional affiliations and collaborations

Crivellin is professionally affiliated with academic departments and research centers collaborating with organizations such as CERN, INFN, Max Planck Society, and university networks across Switzerland, Germany, and other European countries. He maintains active collaborations with researchers at LHCb, ATLAS, CMS, and with theorists linked to IPhT, IPPP Durham, and IHEP. His coauthors include scientists from institutions including University of Zurich, Paul Scherrer Institute, University of Bonn, Universität Zürich, University of Padua, and international partners from Fermilab and SLAC.

He has served on program committees for workshops hosted by Les Houches and KITP, and on review panels convened by European Research Council and national science agencies, contributing to the shaping of priorities in flavor physics and precision phenomenology.

Personal life and legacy

Outside research, Crivellin has engaged in mentoring graduate students and postdoctoral researchers connected to departments and laboratories such as University of Zurich and CERN, contributing to the training of a new generation of phenomenologists. His legacy within the field is reflected in the adoption of his analyses in ongoing experimental interpretations by LHCb and in the continued citation of his model proposals in studies at Belle II and in theoretical investigations at Perimeter Institute and IPMU.
