Our team works on nanomaterials for electrochemical sensors and energy storage devices. Our main area of research is the creation of highly selective biochemical sensing devices. We are primarily interested in synthesizing nanocomposites and biocompatible nanomaterials for biosensors, catalysis, energy storage, and biodegradable and flexible electronics. The creation of highly selective biochemical sensing devices is our main area of research. For instance, finding all the analytes in a single sample could be challenging. In contrast, sample preparation and separation may be necessary for individual analyte detection with high selectivity and sensitivity. To improve the sensitivity and selectivity and lessen interference effects, functionalized nanomaterials (2-dimensional layered inorganic materials, polymer composites, etc.) may be required to improve the devices' performance. Our team is primarily interested in synthesizing nanocomposites and biocompatible nanomaterials for applications such as biosensors, catalysis, energy harvesting and storage, biodegradable electronics, and flexible electronics. I intend to develop prototype chemical and biosensing devices to detect chemical, organic, and microorganism contamination, such as bacteria and viruses, in food and environmental samples.

Our team works on nanomaterials for surface coatings, corrosion resistance, smart coatings, and natural surfactants for corrosion studies. We are also focusing on natural surfactant and ionic liquid-based corrosion studies. We are primarily interested in synthesizing nanocomposites and biocompatible nanomaterials for smart coatings and corrosion studies. Developing coatings with ecologically friendly and sustainable nanomaterials is an advancement, and the types of coating used in eco-friendly corrosion prevention methods are gaining traction in the industry. Nanoclays enhance coatings; mechanical strength and barrier qualities, used in several industries, such as building and packaging. Utilizing cutting-edge analytical and characterization methods, like spectroscopy and in situ imaging, to gain a deeper comprehension of coating performance at the nanoscale and better characterization methods aid in creating more efficient coatings.

Our team is also focusing on energy-related applications like supercapacitors and electrochemical water splitting reactions. We are also working on the synthesis of low-cost nanomaterials for energy storage (supercapacitor, electrocatalyst) applications. We are particularly interested in addressing and understanding the less-explored phenomena, such as etching of components, structural evolution, etc., that are responsible for improving the electrochemical activity of materials. Materials are evaluated on the basis of their extrinsic and intrinsic activities towards electrocatalysis.
