7. Research interest: My research lies at the intersection of statistical physics, nonequilibrium thermodynamics, and complex systems, with a strong emphasis on bridging theoretical insights to real-world technological challenges. I employ interdisciplinary approaches that spanning analytical modeling, computational simulations, and machine learning in order to investigate emergent phenomena in dynamic and disordered systems. I explore impurity diffusion in semiconductor materials, investigating how spatial and temporal variations affect dynamic behaviors at the microscopic level. My work in quantum thermodynamics aims to optimize the performance of quantum heat engines and refrigerators, contributing to the broader understanding of energy efficiency at quantum scales. In the realm of nonlinear dynamics, I explore phenomena such as stochastic resonance and noise-driven signal amplification, especially in nonhomogeneous media, where disorder and fluctuations play crucial roles. I am also fascinated by the links between complex systems, quantum information, and statistical mechanics, particularly how machine learning techniques can be applied to uncover hidden structures and behaviors in physical systems. Through these interconnected areas, my goal is to deepen our understanding of how matter, energy, and information evolve in complex environments, with applications ranging from semiconductor technology to the design of more efficient thermodynamic processes.
