His current research areas are, (1) Developing smart hydrogel-coated microneedles for extraction, sensing, and delivery (hospital on a chip), (2) Bioengineering 2D materials for point-of-care diagnosis of cardiovascular disease biomarkers,  (3) Integrating sensing devices for emerging pharmaceutical contaminants in water resources, (4) Exploring enzyme properties of single-atom catalysts for analyzing oxidative stress biomarkers and gasotransmitters, and (5) Developing laser-scribed graphene electrodes for large-scale applications. 

His experience includes establishing the analytical aspects of a wide range of materials, including tunable redox substrates, carbon nanotubes, graphene, graphene oxide, graphene nanoribbons, transition metal dichalcogenides, binary transition metal oxides and sulfides, graphitic carbon nitrides, biopolymers, hydrogels, porous materials, metal-organic frameworks (MOFs), MXenes, and single-atom enzymes (SACs). He significantly contributed to resolving problems in enzymatic, immunological, aptamer, PCR, LAMP, and nano-catalytic sensors and biosensors. The detection schemes are electrochemical, fluorogenic, and colorimetric.
