August 2026: Had a wonderful week at COSMO-26 in Leiden! Leiden turned out to be a beautiful mini-Amsterdam, steeped in physics history. Hard not to think of Ehrenfest, Kramers, Lorentz, de Sitter, and the rest of the old Leiden school walking those very streets. Talks throughout the week were excellent, discussions were plentiful, and best of all, one of them turned into a brand new project with colleagues from Cambridge!
August 2026: New paper "Analytic Continuation of Conformal Integrals in Momentum Space" out on the ArXiv!
Another very nice collaboration with Jonathan and Prashanth, this time digging into the analytic structure of triple-K and multiple-K integrals that solve the conformal Ward identities in momentum space. We built new series representations that actually converge throughout the physical kinematic region, something existing expansions failed to do.
July 2026: New paper "All Tree-Level Massive Cosmological Correlators via Spectral Gluing" out on the ArXiv!
Incredible working with Jonathan on this one, very pleasant, and quite proud of what we found. We dove into generalised hypergeometric functions of the Lauricella kind, which was a lot of fun, and we uncovered some genuinely beautiful combinatorics hiding behind seemingly terrifying expressions.
June 2026: Had a really nice week visiting the UK, with talks at the University of Cambridge and Imperial College London!
Always a pleasure to catch up with colleagues, get fresh eyes on ongoing projects, and discover new corners of the UK cosmology community. Thanks to everyone who made the trip so enjoyable!
April 2026: Two new preprints out on the ArXiv: "Kontorovich-Lebedev-Fourier Space for de Sitter Correlators" and "Universal Non-Gaussian Signatures from Transient Instabilities"!
A fun pair of projects with Nathan, Arthur and Sébastien on the mathematical side of de Sitter correlators, and with Shuntaro and Diederik on new non-Gaussian signatures from transient instabilities.
January 2026: New paper "De Sitter Momentum Space" released on the ArXiv!
Joint work with Nathan, Arthur and Sébastien, continuing our effort to build new mathematical tools for cosmological correlators.
September 2025: "The Exact and Approximate Tales of Boost-Breaking Cosmological Correlators" was published in JCAP!
With Zhehan, Sébastien, Xi and Yuhang. Check it out if you're curious about boost-breaking effects in cosmological collider signals.
June 2025: Thrilled to share that I have successfully defended my PhD!
It was an incredibly emotional and rewarding moment, made even more special by the presence of my family, friends, and colleagues. Their support and encouragement have been invaluable throughout this journey. Grateful for this milestone and excited for what lies ahead!
