Aditya Kumar LankapalliDoctoral Researcher
My research focuses on computational pathogen genomics with special interest in comparative genomics and methods development.
Main interests include:
- Screening for specific bacterial genomes from metagenomic data sequenced from bones/teeth isolated from archaeological remains from ancient time.
- Performing comparative analysis on the reconstructed ancient bacterial genomes to contemporary genomes.
- Phylogenetic Analyses
- Development of pipeline for detection of recombination patterns in bacterial genomes.
- Development of tools for bacterial genomic analyses.
Currently I am developing a pipeline for detection and characterisation of recombination patterns in bacterial genomes.We compare various tree models to a whole genome phylogeny and identify genomic regions with a contradicting tree model might be explained by recombination. By assessing genomic regions with respect to their phylogenetic signals possible recombinant regions across a bacterial genome of interest are identified.
