Abstract
As a PhD candidate in Environmental Health at South Dakota State University, my current research focuses on the characterization and source apportionment of airborne particulate matter and bioaerosols in swine production facilities. I employ advanced molecular techniques including Oxford Nanopore-based 16S rRNA and shotgun metagenomic sequencing to profile the microbial composition of PM₂.₅ and PM₁₀. This work provides novel insights into the diversity of airborne pathogens and antibiotic resistance genes (ARGs) in agricultural environments, supporting the development of targeted mitigation strategies.

In a parallel study, I utilize particle size distribution (PSD) data and EPA’s Positive Matrix Factorization (PMF) model to identify key PM sources within swine barns and associated environments. This integrative approach bridges physical aerosol characteristics with microbial source tracking, enhancing our understanding of occupational exposure risks.

Previously, I worked as a research fellow at Satyawati College, University of Delhi (2018–2022), where I conducted microbiological and molecular characterization of airborne pathogens from diverse microenvironments. My work explored the impacts of bioaerosols on respiratory and cardiovascular health, and I have presented my findings at various national and international conferences. Additionally, I have co-authored 15 peer-reviewed publications in reputable journals such as Journal of Hazardous Materials, PLoS ONE, and Science of the Total Environment.

I am seeking postdoctoral opportunities in the areas of bioaerosol science, air quality, and microbial exposure assessment. I am available to begin a position in summer 2026 and open to relocating within the U.S. or internationally. My long-term goal is to contribute to interdisciplinary research that informs public health interventions and sustainable livestock management practices.
