VEENA MANMOHAN

Bioinformatics graduate with a microbiology background and hands-on experience in genomic data analysis, viral genomics, metagenomics, sequence analysis and statistical programming. Proficient in R, Python, Linux and bioinformatics tools including MAFFT, MrBayes, BLAST and Kraken2. Seeking bioinformatics, microbiology, genomics or computational biology opportunities in biotechnology and research environments.

Viral Genome Comparative & Phylogenetic Analysis

• Analysed 32 ToCV and 69 ToMV viral isolates to investigate genomic relationships and evolutionary patterns.

• Retrieved and processed viral genome sequences using NCBI/Entrez; performed multiple sequence alignment with MAFFT and trimming with trimAl.

• Constructed phylogenetic analyses using MrBayes and translated nucleotide sequences into proteins for BLASTp analysis of conserved proteins.

Shotgun Metagenomic Analysis of the Human Gut Microbiome

• Processed shotgun metagenomic sequencing data using fastp, FastQC and MultiQC.

• Performed taxonomic classification with Kraken2 and generated microbial abundance profiles.

• Conducted downstream statistical analysis in R using tidyverse and vegan; calculated Shannon, Simpson and observed-richness measures.

• Performed Bray–Curtis beta-diversity analysis and visualised microbial community composition using ggplot2.
