My research interest lies in complex systems. We investigate the roles of fluctuations and time delay in non-equilibrium reaction systems. We analyse the data generated by complex systems such as time series data of earthquakes or two dimensional spatial images for multifractality. Fractal dimension is an important measure of complexity. Recently, I am interested in complex biological systems. Complex diffusion dynamics is ubiquitous in complex biological systems such as living cells. In particular, I am interested in the transport dynamics of active particles in complex environment. We investigate anomalous diffusion dynamics of these active particles with stochastic modelling, statistical analysis and data science approaches.

I am interested in studying fundamental principles from the first principle. String Theory realizes the emergent spacetime for studying Quantum Gravity. One can use the strongly coupled boundary theory to probe Quantum Gravity Theory. I am interested in using the quantum information perspective to study the weak-strong dual. It is hard to calculate the strongly-coupled field theory so far. Therefore, I am also interested in developing calculation skills and numerical methods for studying the strongly coupled theory. Because String Theory is Theory of Everything, the study also motivates other theoretical interests to the similar research problems.

My main research interest is examining the relation between string theory and QCD, utilizing the two possible approaches of holographic QCD on one hand, and effective string theory on the other. In particular, I am currently working on computing scattering amplitudes of hadrons using these tools. Recently I have worked on the study of chaotic behaviour in string theory, and on constructing interacting supersymmetric higher spin gravity theories.

My research focus is on Nonlinear Dynamics with a special emphasis on the evolution of coherent wave structures. Dynamics of nonlinear systems reveal several interesting phenomena that lead to a better understanding and influential applications in different fields of science, engineering and technology due to the existence and non-trivial dynamics of various nonlinear coherent structures like solitons, breathers, rogue waves, lumps, dromions, etc. One of the critical questions is the interconnection between these nonlinear waves and possible unification mechanisms, which will help their realization and identify possible transformation among them. To understand various nonlinear waves, I shall concentrate on certain existing as well as new higher dimensional and multicomponent nonlinear models arising as the governing equations in different physical contexts. Furthermore, I shall devote myself to investigate their intriguing propagation and interaction dynamics.

My research focuses on theoretical cosmology with Gravitational Wave physics and Modified Gravity models for releasing H0 tension. I am skilled in comparing the theoretical model with the observations numerically by kinds of programs. In the past, I have studied the anisotropic Universe, CMB power spectra, and Large Scale Structure in the dark energy models.

I am interested in applying ideas from quantum information, in particular entanglement entropy, to the study of condensed matter physics and quantum field theory, with an emphasis on non-equilibrium phenomena like quantum chaos and Floquet physics. In previous work, I have used information scrambling to characterize quantum chaos in many-body systems. Lately, I have turned my attention to the studying entanglement dynamics in spatially inhomogeneous quenches. Another direction I have been working on is the study of topological defects in Floquet systems. I plan to continue to explore these directions as well as other topics involving the application of quantum information concepts to condensed matter physics and quantum field theory.

My primary research interest is in non-equilibrium quantum many-body systems and understanding the associated exotic phases of matter. I am pursuing this goal along a number of different lines, including transport processes in ultra-cold atomic gases, dissipative open quantum systems and the dynamics of quantum magnets. In general, I employ a combination of analytical and numerical tools, and my work is often motivated by real experiments. Recently, I have been considering the effect of interactions in open quantum systems with non-reciprocal dynamics that display a diverging relaxation timescale via the so-called “Louivillian skin effect”. Going forward, I propose to investigate this from the perspective of universality and critical phenomena. I have also been analyzing the relaxation dynamics of multimode Bose-Einstein condensates with a view toward atomtronics, an analogue of electronics for neutral atoms. Understanding the dynamics of ultra-cold atoms and developing atomtronic devices remains an ongoing research endeavor.

The search for quantum gravity as a quantization of General Relativity has been carried for a long time and recently has given promising results. The research had been evolved into various tracks, which extend from the perturbative to the non-perturbative approaches. Since gravity is perturbatively non-renormalizable, the non-perturbative approaches have the advantage to avoid the problem. They could be broadly categorized into two main branches: the string and non-string approach. One of the candidates of the non-string approach is loop quantum gravity (LQG), which is standardly- based on the rigorous Dirac quantization procedure [1]. As a consequence of the theory, the spectrum of the area and volume of space are discrete, for the case of pure gravity with no matter-coupling. This indicates the existence of the quanta of space, described by spin-networks: a lattice-graph labeled by spin representations of SU(2). The graph may contain loops, where the SU(2) holonomies, describing the intrinsic curvature of a finite region of the space, are located.

My research field is physics beyond the standard model, especially Higgs related theoretical and phenomenological studies. Since discovery of the Higgs boson, it can serve as a door to new physics. I am interested in the anomalous Higgs couplings through both the main and rare production and decay channels. Higgs CP property studies also appeal to me. We can perform these collider phenomenology researches in both specific new physics models and the effective field theory framework.

The Higgs boson discovery serves as the evidence for the importance of scalar in elecroweak symmetry breaking. However, the order of phase transition and the role of additional scalar or multiplets is yet to be discovered. My research focusses on fate of the electroweak vacuum and the order of phase transition. I am interested in studying the order of phase transition with the dark matter constraints from new packages as MadDM and GAMBIT. I am also interested in exploring the effect of CP-violating pahses in explaining the baryon asymmetry of the Universe in beyond Standard Model scenarios.
