We have a wide range of interests (Not all those who wander are lost!). 

Our experimental condensed-matter research focuses on both fundamental science and real-world applications, utilizing spectroscopic, microscopic, electrical, and electrochemical tools. We employ cutting-edge techniques, including ultrafast photoconductance and photoluminescence measurements, in situ Raman spectroscopy, atomic force microscopy, and various electrochemical methods to study low-dimensional materials and materials for energy generation/storage.

In terms of numerical approaches, we use quantum calculation tools like KWANT and TKWANT for computational modeling and rely on COMSOL Multiphysics for finite element analysis. We develop physics-informed machine learning tools for predicting materials properties (e.g., thermal conductivity).

A new theoretical area in our group focuses on using noisy intermediate-scale quantum (NISQ) computers for studying Bell-type tests. We are using quantum algorithms to fit biophysical data (e.g., epistatic mutations, ion-channel data) and to identify novel features in quantum spin liquids.

We use electrical and electrochemical graphene field-effect transistors along with fluorescence imaging and cirular dichroism for biosening.

These efforts have been funded by NASA, SC EPSCoR, NIH, the US Army, and other industrial partners. 

(Click to expand) 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. In a recent publication, we investigated the effects of quantum capacitance in Li-S batteries. 

Photonics: By manipulating non-linear optical properties of two-dimensional materials (graphene and MXenes), we fabricated photonic diodes that break time-reversal symmetry to achieve passive non-reciprocal light transmission. 

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.

Quantum biology and 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 graphene’s high conductivity.
