Some current areas of interest are:
Cosmological Correlators
The accelerated expansion in the early universe is both a blessing and a curse. On one hand, the strong gravitational fields provide a high-energy environment which probes the universe on the most fundamental length scales. On the other hand, any signatures of new physics are rapidly diluted away, leaving behind only a faint imprint of long wavelength fluctuations on the primordial matter distribution from which our universe grows.
By applying modern field theory techniques (effective field theory, scattering amplitudes) to the cosmological correlators, we can learn about sources of primordial non-Gaussianity in the early Universe and extend the high energy frontier beyond what is possible with terrestial colliders. In particular, developing consistency conditions such as unitarity and locality of the interactions present during inflation can then be used as theoretical priors to improve the constraining power of our measurements.
