Research Focus:

1. Human microbiome in health and disease

The human body is inhabited by abundant microorganisms, including bacteria, archaea, viruses, fungi, protozoa etc. collectively known as human microbiota. The advent of a new sequencing era like high-throughput DNA sequencing and metagenomic studies have explored the highly diverse and dynamic nature of the microbial communities and their crucial role in human health and in disease.

We have several collaborations with experimental and clinical laboratories in order to analyse the human microbiome data at different taxonomic levels as well as functional potentials between diverse microbial communities for understanding human health and diseases that are associated with the microbiota.

2. Multi-omics data mining and methods development

Recent advances in multi-omics (metagenomics, metatranscriptomics, metaproteomics and metabolomics) technologies created new avenues to explore the dynamic relationships between molecular events and clinical outcomes using quantitative methods. However, the extraordinary range and complexity of these omics data have faced critical computational bottlenecks requiring emerging concepts and methods. We work in collaboration with our data science department in order to develop new computational framework to integrate big data mining algorithms with high-performance computing strategies for revealing the complex relationships between multi-omics patterns and phenotypic outcomes. This will enhance the integration of different data types and the interpretation of results from multiple aspects.

3. Comparative genomics and genome adaptation

The genome divergence is a dynamic evolutionary process of ecological and genetic differentiation. A considerable portion of the genetic diversity is likely to be considered as regulators of adaptive features associated with particular habitat. One powerful approach to unraveling the molecular mechanisms of adaptation is the comparative genomics study with large number of complete genome sequences. In this regard, the pan-genome approach, has been found to be valuable in the comparative analysis for a set of genomes.

We employ the comparative pan-genomic study coupled with evolutionary analyses as a framework to investigate the genome diversification associated with various life-style/pathogenicity. This framework is very useful in deciphering the contingent contributions of evolutionary processes along with the selective pressures that can potentially shape the genomic and metabolic diversification.
