|RESEARCH INTERESTS||My research interests are on the development of nanoscale and nano-enabled materials that offer new possibilities for the development of novel remediation and environmental sensing/monitoring technologies for water, soil and air. The ideal sustainable material must be able to coordinate different functionalities and exhibit the potential for reusability. In the recent past, I have been drawn into looking at the use of safe extraction procedures of flavonoids, nanotechnologies for stabilization of these extracts and application/modification of phase-inverted nanomebranes. In addition to the general application of Green Chemistry in solving day-to-day environmental problems.|

|GRADUATE RESEARCH||My PhD research was in Environmental Nanoremediation Chemistry, which focused on environmental detoxification and development of sensors. We developed a sensor for the detection of fullerenes and engineered aerosols in the environment and reported the first evidence of the removal of Cr(VI) from environmental samples using a new water-soluble derivative of quercetin called quercetin pentaphosphate (QPP) and flexible poly(amic) acid (PAA). Quercetin was selected because it is naturally occurring and has excellent metal chelating properties. Whereas, PAA is a conducting electroactive polymer, and its properties can be tuned by manipulating the delocalized π electron system for chemical and electrocatalytic applications. In addition, I collaborated with Harvard School of Public Health on a project on capture and electrochemical detection of industrially relevant aerosols and microbes using phase-inverted PAA membrane.|
