Kamran Salehi Vaziri
After completing my master’s degree at the University of California, Riverside, I earned my PhD at EPFL (École Polytechnique Fédérale de Lausanne) under the supervision of João Penalvaes. My thesis was titled Non-perturbative Quantum Fields during Curved Spacetimes.
In 2022, I joined the University of Amsterdam as a postdoctoral researcher. In 2025, I was awarded a VENI individual grant, and I currently work at the University of Amsterdam as a VENI fellow.

Research
My research interests broadly encompass quantum field theory, holography, and cosmology. In particular, I study de Sitter physics using perturbative and non-perturbative methods across different regimes. I specialize in applying techniques from the S-matrix bootstrap and conformal bootstrap to derive constraints and bounds on physical observables in the early universe from fundamental physical principles.
