Research

Comparative genomics: developing bioinformatics algorithms and computer tools

   
Cryptic Language of the DNA
software development (DNA Punctuation); detection, visulazation and comparative analysis of short palinddromes and direct repeats
   
   Orthologous Gene Families

phylogenetic algorithm (BranchClust), genome annotation, evolution of large homologous superfamilies, domain migration in and accross genomes

   Horizontal Gene Transfer
phylogentic methods to detect horizontal gene transfer, software tool (GPX) that applies machine learning algorithms such as self-organizing maps (SOM) to genome spectrum (bipartition and quartet) analysis

    Visual genomics
application of method of 2D DNA walk to various chromosomes from bacteria to humans to study functional and structural organizations of chromosomes of different organisms.
