ABOUT ME

An accomplished Environmental and Inorganic Chemist with over 19 years of teaching and research experience in Analytical, Environmental, and Inorganic Chemistry. Possesses strong interdisciplinary expertise in addressing emerging environmental challenges, particularly in air pollution, particulate matter chemistry, and contaminant exposure pathways. Demonstrates proficiency in analytical instrumentation, including like AAS, ICPMS, UV–Visible Spectrophotometry, and Colorimetry, along with environmental monitoring techniques for trace-level detection of pollutants. Skilled in experimental design, environmental sampling, chemical characterization, and interpretation of complex datasets using modern analytical and statistical tools. A well-established researcher with significant academic contributions, including books, book chapters, and numerous peer-reviewed publications in reputed national and international journals, with over 1050 citations. Actively engaged in disseminating research findings through international and national conferences, extended abstracts, and scholarly presentations.

Core Research Areas

• Atmospheric & Aerosol Chemistry: Study of particulate matter (PM₂.₅, PM₁₀) dynamics, transformation processes, and their role in Air Quality Index (AQI) evaluation

• Microplastics & Nanoplastics in the Environment: Investigation of microplastic and nanoplastic particles in air (PM₂.₅ fraction) and water systems, including their sources, transport, transformation, and environmental persistence

• Source Apportionment Studies: Identification of indoor and ambient sources of particulate matter and plastic-derived particles using chemical and physical markers

• Chemical Characterization of Particulates: Analysis of trace metals, toxic/heavy metals, and carbonaceous components (organic carbon and elemental carbon), including plastic-associated additives and residues

• Environmental Monitoring of Gaseous Pollutants: Measurement of CO₂, CO, SO₂, NOₓ, O₃, and related atmospheric gases

• Soil Chemistry & Carbon Cycling: Quantification of soil organic carbon and its ecological significance

• Exposure Science & Health Risk Assessment: Evaluation of human exposure to airborne particulates, toxic metals, and micro/nanoplastics, with emphasis on inhalation and ingestion pathways and associated health risks
