Biomedical Data Research Lab

Biomedical Data Research Lab is a computational systems biology lab led by Chi Zhang, PhD, and Sha Cao, PhD, from Indiana University School of Medicine. The lab develops new computational methods to mine and integrate biomedical omics data and develops new statistical learning methods for semi-supervised or unsupervised pattern detection from high dimensional data. The current research projects include method development for (1) biological explainable model of cellular and tissue level changes from scRNA-seq and bulk tissue data, (2) cell type specific transcriptional regulation from single cell multi-omics data, and (3) matrix, tensor and high order tensor local low rank representation.

NIGHMS 1R01GM131399-01 Construction of cell type specific gene co-regulation signatures based on single cell transcriptomics data

The major goal of this project is to construct a computational infrastructure to derive cell type specific gene co-regulation signatures that can form reference map of certain cell types by integrating single cell RNA-Seq data with epi-genomics data.
