Biotechnology graduate with research experience at IIT Madras, analyzing RSV-infected airway samples to identify genes linked to host–pathogen interactions.

Message

At IIT Madras, I conducted transcriptomic analysis of RSV-infected airway epithelial samples for a project on respiratory infection in Primary Ciliary Dyskinesia. I analyzed two RNA-seq datasets to identify differentially expressed genes associated with host–pathogen interactions.

I used Linux, RStudio, DESeq2, and limma, and explored single-cell RNA-sequencing workflows with Seurat. I also documented computational workflows and research findings.

At Rajalakshmi Engineering College, I designed and evaluated an edible herbal toothpaste, assessing its stability, antimicrobial activity, and physicochemical properties. I also co-authored a peer-reviewed review article on microbial bioremediation strategies for heavy-metal remediation.
