Research Statement

My research career began with the study of magnetic materials and later expanded to include metastable states in disordered granular systems, superconducting quantum devices, and energy storage in nanoscale structures. My work lies at the intersection of condensed matter physics, nanoscale materials engineering, and emerging computational technologies.

Multilayered Magnetic Films and Magnetic Anisotropy In my doctoral research, I investigated the magnetic properties of multilayered Co/Ti-Mo/Co thin films, focusing on how their crystal structure and magnetic domain structure relate to magnetic anisotropy. I studied how different factors (such as the composition of the Ti-Mo interlayers, the thickness of the layers, and the presence of an external magnetic field during deposition) affect both the structure and magnetic behavior of these films. My work demonstrated how Ti-Mo interlayers influence the structural and magnetic parameters of multilayer magnetic films. I found that the film structure and magnetic anisotropy depend strongly on the titanium content in the interlayers. Notably, I also showed that even multilayer films with an amorphous structure can exhibit magnetic anisotropy. These findings suggest that such multilayer structures have promising potential for use in magnetic recording and readout heads.

 Induced Seismicity in CO₂ Geological Storage In this interdisciplinary research, I examined the micro- and nano-scale mechanics of granular rocks and their response to fluid injection, with particular emphasis on mechanisms driving induced seismicity during liquid-phase CO₂ injection and withdrawal. My research showed that grain-level rearrangements at these small scales can trigger spontaneous strength relaxation in disordered rocks, increasing their seismic susceptibility. These findings enhance our ability to predict and mitigate seismic activity in carbon-storage formations and support national efforts toward safe, long-term CO₂ geological storage.

 Multifunctional Superconducting Devices for Quantum Memory, Sensing, and Computation My research advances the development of superconducting systems for quantum sensing, memory, and computing. I have contributed to the creation of scalable superconducting nanobridge-based memory devices that operate reliably at liquid-helium temperatures, enabling low-error, nonvolatile cryogenic memory. My work also led to developing superconducting island arrays on topological insulators that function as highly sensitive magnetic-field sensors and superconducting diodes. Together, these efforts support the realization of multifunctional superconducting devices that integrate sensing, memory, and computation for next-generation quantum technologies.

 Advancing Energy Storage with Nanocapacitor Batteries Currently, my research focuses on developing next generation of nanocapacitor batteries. I developed the novel technique to store energy within the dielectric, achieving significantly higher energy densities than conventional capacitors. These devices are smaller, more cost-effective, faster-charging, and more efficient than traditional lithium-ion or lead–acid batteries, offering a promising path toward advanced energy-storage technologies.
