The research interests of our lab are at the interface of physics, biology, and nanoscience. Our lab aims to seamlessly integrate the principles of condensed matter physics, optical spectroscopy, and physiological chemistry to understand physics at the nanoscale and nano-bio interfaces.
We elucidate new physical phenomena at the nanoscale by studying fundamental excitations such as electrons/phonons at both equilibrium and non-equilibrium, carefully alter material structure, design novel material architectures based on our fundamental understanding to surpass natural limitations. Ultimately, we also scale up processes to translate our fundamental discoveries to devices.
Some examples of our successes are below:
Energy storage: In this work, beginning from a fundamental understanding of atomic vacancies in graphene, we demonstrated new methodologies to surpass quantum capacitance limitations and achieve devices at the pouch cell level.
Photonics: Through the manipulation of non-linear optical properties of two-dimensional materials (graphene and MXenes), we were able to fabricate photonic diodes that break time-reversal symmetry to achieve passive non-reciprocal transmission of light.
Biosensors: Using Langevin quantization of circuit quantum electrodynamics, surface plasmons in nanoparticles, and delocalized pi-electron cloud in graphene , we successfully demonstrated highly sensitive biosensors with femtomolar sensitivity.
Nanotoxicity: We established new relationships between defect-induced electronic states in nanomaterials and corresponding cellular responses.
Energy generation: In this project, we achieved wireless energy transmission by leveraging asymmetry in polymers combined with high conductivity of graphene.
