معرفی
Gizem Şengör is an Assistant Professor and Full-Time Faculty Member in the Department of Physics at Boğaziçi University, Istanbul, Turkey. She holds a PhD in Physics from Syracuse University (2018) and completed her MS and BS at Boğaziçi University. Her research lies at the intersection of cosmology, quantum field theory, and symmetries in curved spacetimes, with a focus on de Sitter spacetime, early universe physics, and cosmological perturbations.
Her educational background includes:
- PhD in Physics, Syracuse University (2013–2018), Thesis: 'Cosmological Perturbations in the Early Universe', Advisor: Associate Professor G. Scott Watson
- MS in Physics, Boğaziçi University (2011–2013), Thesis: 'From Five Dimensional Flat Spacetime to Our Four Dimensional Braneworld via Kaluza-Klein', Advisor: Professor Metin Arık
- BS in Physics, Boğaziçi University (2007–2011)
Her research interests center on theoretical aspects of modern cosmology, especially the role of symmetries in accelerating universes, quantum field theory in de Sitter space, and the behavior of perturbations during inflation and preheating. She explores fundamental questions about unitarity, information, and boundary structure in cosmological settings, often using effective field theory and group-theoretic methods. Her work bridges mathematical rigor with physical insight into the early universe.
The analysis of her recent publications reveals a strong focus on de Sitter spacetime, particularly its late-time boundary, correlation functions, and unitarity issues. She investigates how symmetries constrain cosmological models and how quantum fields behave in expanding backgrounds. Her work often connects to holographic principles and the dS/CFT correspondence, aiming to understand the quantum nature of spacetime in an accelerating universe.
Her scientific awards include:
- 2020 MSCA Success Stories in Widening Countries
- 2017 Henry Levinstein Distinguished Senior PhD Student, Syracuse University
- 2014 Henry Levinstein Fellowship Award, Syracuse University
She has led and coordinated significant research projects, including the Marie Skłodowska-Curie Individual Fellowship 'SymAcc' (2019–2021) at CEICO, Czech Academy of Sciences, and currently leads the TÜBİTAK 2232-B project 'Quantum Field Theory in a de Sitter Universe: from particles to information' (2022–2025) at Boğaziçi University. She has delivered numerous invited seminars at institutions such as Imperial College London, Cambridge, and Amsterdam, reflecting her active engagement in the international theoretical physics community. She advises students and contributes to advancing research in cosmology and fundamental physics.
She is involved in research groups and collaborations including the de Sitter Cosmology Group and participates in workshops such as the CORFU Summer Institute. Her ongoing projects aim to deepen our understanding of symmetries and degrees of freedom in cosmic acceleration, with implications for quantum gravity and cosmological model building.
