We are very happy to announce an online school on quantum field theory in Bangladesh, going all the way from basics to topics of current research! Registration opens on June 1st: indico.ictp.it/event/10720/ Co-organized w/ Ahmed Rakin Kamal, w/ generous support from ICTP PWF.

life was so easy back then :(

It was fun teaching a one-week, mini-course on cosmological correlators Imperial College London MSc in QFFF Hand-wrriten notes available here sites.google.com/view/sadrajaza…

A long summer ahead in the renovated home office (got the screen for £10; so highly recommend gumtree :) )

#TalentsCNRS🥉Toutes nos félicitations à Sébastien Renaux-Petel, chercheur CNRS 🌍, récompensé cette année par la médaille de bronze du CNRS 🌍 pour ses travaux sur l'exploration des infinitésimales fractions de seconde de l’après Big Bang. ➡️inp.cnrs.fr/fr/personne/se…

Having a great time at the University of Southampton EuroString24 meeting with some amazing talks. As a bit of an outsider, I’m excited to sneak into the string community and give a talk tomorrow on an upcoming work on correlators. Slides are already up! indico.cern.ch/event/1374516/…

We’re hiring two postdocs in theoretical physics at Institut des Hautes Études Scientifiques - IHES. Apply to come work with us! academicjobsonline.org/ajo/jobs/29026

Imperial College London Imperial College London Imperial Physics is hiring a Postdoctoral Research Associate in theoretical cosmology/quantum field theory from 1 October 2025. Application deadline 15 December. academicjobsonline.org/ajo/jobs/29340

I recently lectured at GGI INFN on the cosmological bootstrap. The lectures are available on Youtube, youtube.com/playlist?list=… I give an overview of cosmological perturbation theory, and bring the students up to date to some of the latest developments in the field.

You can register now at indico.cern.ch/event/1487633/…

Where are the masses? Stay tuned for next Week ;)

registration deadline in 2 weeks!

Suvrat Raju taught an introductory QFT course in ICTS last year. Link to playlist below. 👇

What I like about outreach talks is that everyone who participates truly listens (e.g. saw no laptops)! It was fun talking to undergrads at Imperial about "Universe as a Lab for Fundamental Physics". Slides: dropbox.com/scl/fi/lsbu63w…

We have a new paper out today where we develop a way to directly compute scalar in-in correlators from Feynman diagrams in flat space. This allows one to take any diagram and integrate over energy with a simple Kernel to obtain the in-in correlator in dS! arxiv.org/abs/2503.10598

I do not forgive whoever was the cause 😢
