Advanced biomedical research requires systems biology approaches where bioinformatics and computation biology play an important role. The primary research in the Laboratory of Computational Functional Genomics is the development of methods for analysis and integration of omics data to understand underlying mechanisms, derive new hypotheses, and identify therapeutics in human and animal studies. We are also interested in modeling host-microbiome interaction to understand its role in shaping the wellness or disease of the human body

The microbiome has been shown to have an impact on the development of various diseases in the host. Being able to make an accurate prediction of the phenotype of a genomic sample based on its microbial taxonomic abundance profile is an important problem for personalized medicine. We developed a deep learning framework, a Convolutional Neural Network (CNN), for such a prediction. To facilitate the CNN learning, we explore the structure of abundance profiles by creating the phylogenetic tree and by designing a scheme to embed the tree to a matrix that retains the spatial relationship of nodes in the tree and their quantitative characteristics. The proposed CNN framework is highly accurate, achieving a 99.47% of accuracy based on the evaluation on a dataset 1967 samples of three phenotypes. Our result demonstrated the feasibility and promising aspect of CNN in the classification of sample phylotype.
