Presentaions

Here are some of the slides from my talks that would be adequate for students considering joining MCNS. Without oral explanations, you would not fully understand the contents, but you would get some ideas about the topics of my research.

Cosmology Models Outside the Swampland

01.08.2025@Cosmic Connections: Bridging the Early and Late Universe, IMSc, Chennai

A critical assessment of the swampland program applied to cosmology, and possible ways forward.

Contains a short review on effective field theory (EFT).

Toward a general cosmology audience.

Our Quantum Origin in the Universe

17.07.2025@IIA

Focus on extra-natural inflation and the Weak Gravity Conjecture.

Contains a review of inflation, EFT, swampland program.

Toward a general astrophysics audience.

Advances in Quantum Gravity and Cosmology

16.07.2025@IUCAA Sponsored Seminar on Advances in Cosmology, CHRIST, Bangalore

Picked up the Trans-Planckian Censorship Conjecture from the swampland conjectures.

Contains a review of primordial density perturbation from inflation, QFT, EFT, swampland program.

Toward a bachelor-level audience and above, but talked about advanced topics.

Sources of Gravitational Waves from Particle Physics and String Theory

04.04.2025@InPTA online colloquium

From Superstring Theory to Gravitational Waves

12.03.2025 @MCNS

More on introduction to superstring theory than gravitational waves.

A little bit about the logic of science in the beginning.

I wanted the audience to think critically, not just accept what was told.

Reference to related recent talks and courses at MCNS.

How did the universe begin? How do scientists know it?

31.08.2024@MCNS

Also here, I wanted the audience to give thoughts on the logic behind the current theory of how the universe began, and the observational evidences to support it.
