Computational and Integrative Biology Group

Bioinformatics is an interdisciplinary that combines biology, computer science, and information technology to analyze and interpret biological data. It involves the development and application of computational methods, algorithms, and software tools to understand biological processes, analyze large datasets, and make predictions about biological systems.
Bioinformatics plays a crucial role in many areas of biological research, including genomics, proteomics, structural biology, evolutionary biology, and systems biology. It is used to analyze DNA sequences, protein sequences, gene expression data, protein structures, and biological networks. Bioinformatics tools and techniques enable researchers to identify genes, predict protein functions, study genetic variations, analyze evolutionary relationships, and much more. We aim to explore:

  • Data-driven research in development, ageing and evolution biology;
  • Machine learning methodology and its applications in biomedicine;
  • Developing and maintaining bioinformatics database and software;
  • AI and drug discovery.

    Research Summary

    Clustering in single-cell RNA-sequencing

    As one of the core steps of single-cell transcriptome data analysis, clustering plays a crucial role in identifying cell types and interpreting cellular heterogeneity. We summarize applications and challenges of the clustering ensemble method in single-cell transcriptome data analysis, and provide constructive thoughts and references for researchers. (Nie X., et al. Computers in Biology and Medicine, 2023).

    Additives and Toxicological Mechanisms

    Additives have the potential to affect the survival and lifespan of insects, but the full molecular mechanisms behind mortality and infertility remain unclear. By integrating molecular biology and multi-omics approaches, we focuses on uncovering the potential adverse effects of different food additives on the growth and developmental pathways of fruit flies. (Li L., et al. in press, 2024).
