For interested people who want less technical details, I suggest you watch the documentary on the Higgs Boson discovery at LHC. It was one of the discoveries that sparked my interest in particle physics. I hope it interests you too. You can also watch this video that beautifully discusses the story of one of the most accurate theories of nature we have created - The Standard model, despite its dull name :D!
You can find the list of my research interests below and resources to learn more about them.
My research revolves around these topics mostly, But I want to expand and explore various other topics in near future!
The universe we observe comprises mainly of matter rather than equal amounts of matter and antimatter as one would naively expect. Every star, dust could, planet, and whole galaxies seem to be made of matter than antimatter. This asymmetry is measured experimentally from Big bang nucleosynthesis and Cosmic microwave background (CMB), whose physics are sensitive to the value of baryon asymmetry. This is known as the baryon asymmetry problem. Due to various theoretical considerations such as Inflation, the observed baryon asymmetry should have been generated dynamically in the early universe through some mechanism. The term "baryogenesis" is collectively used to refer to such mechanisms. Various ideas such as GUT baryogenesis, Electroweak baryogenesis, and Leptogenesis have been proposed to explain this asymmetry. Leptogenesis is the most studied mechanism due to its connection with neutrino physics. You can read more about it here. Some good resources to learn about the theory of baryogenesis are,
During the 20th century, people observed that the velocity curve of galaxies did not match theoretical predictions. This pointed to the fact that there must be some invisible matter (which does not interact with light) that accounts for this missing mass which we now call Dark matter. Since then, there have been various experimental observations, such as Bullet clusters, Gravitational lensing, which can be explained using dark matter. The Standard Model (SM), which explains most of the physics we observe, does not have a dark matter candidate. Thus it requires an extension of the Standard Model to account for this invisible matter than makes up roughly 26% of the universe. Other approaches try to modify the equations of General Relativity to account for the phenomena, but this idea has its cons. Below is a list of resources that will give you a basic idea of Dark Matter and its relations with other problems of SM
One of the most mysterious particles in the Standard Model of particle physics is the neutrino due to its weak nature. They interact very weakly with matter making it challenging to study. Neutrinos were massless when the Standard Model was proposed as a theory of leptons and quarks. However, later various observations, such as neutrino oscillations confirmed by KamioKande, pointed out that neutrinos should have mass. Recent experiments such as KATRIN have put stringent upper bound on the sum of the masses, and the difference of mass squared are measured experimentally from oscillations experiments. Thus there is strong evidence for the existence of neutrino masses. The expected neutrino mass scale is in meV. Such a light neutrino suggests that there could be some mechanism behind its masses apart from the Higgs mechanism. Therefore neutrinos could be a probe to study physics beyond the Standard Model. There are also some theoretical connections between neutrino and dark matter physics which future experiments might reveal. You can learn the history of neutrinos here.

All the known particles have masses, as we have observed experimentally. When the Standard Model was proposed as a theory for the interaction of leptons and quarks, none of the fermion and bosons had mass as we would expect. The solution to the problem came in the form of the Higgs mechanism. Finally, in 2012, LHC found a Higgs like particle, which completed the long-standing quest of answering a mass problem in the standard model. Various questions have arisen after the discovery, such as whether the observed particle is the same as the Higgs predicted by the standard model? If not, what is the phenomenology of the Higgs and other possible scalars beyond SM? How can we study the parameters more precisely from collider experiments such as in LHC third run? You can learn about Higgs here. Some resources to learn about the theory of Higgs are,
