Primordial Magnetic fields
Magnetic fields are ubiquitously present in our observations of the universe. They are present around the Earth, where they are powered by Earth’s turbulent core, around the sun they are powered by the convective motion of the solar plasma, and around our galaxies due to the motion of charged particles. However, recent observations have also found hints of magnetic fields in the depths of cosmic voids, where we do not expect any significant sources of magnetic fields to be present. One simple and natural explanation for these cosmic magnetic fields could be that they are primordial, i.e. they were produced in the very early universe from the plasma formed after the Big Bang.
I am interested in exploring novel strategies that can be used to verify (or refute) the primordial nature of the cosmic magnetic fields. Click here to see the list of my projects on this topic.
Early Universe cosmology
In standard cosmology, all the Standard Model particles equilibrate with each other to form a thermal plasma in the early universe (within ∼1 second of the birth of the universe). This thermal state washes out any information of the prior history. Consequently, we have little to no information about the state of the universe prior to one second of its birth.
I am interested in exploring novel ways the standard early universe cosmology can be altered and that can lead to potentially observable signals. Even in the absence of such signals, we can learn quite a bit about fundamental physics that is far beyond the scope of terrestrial experiments.

Miscellaneous projects
Other research projects that do not fall into the above categories are listed here. These projects are the ones I undertook early in my research career.
Fun robotic projects
Before begining my academic career in physics, I was training to be a mechanical engineer. During those years, I have built several fun robots and you can check them out Here.
