Project description:

Identifying correlations in cell-state transitions

Recent advanced and increased sophistication in collecting single-cell RNA seq data has led to a need for quantitative tools to understand and interpret this data. We approach this problem from a theoretical perspective. Recent work has identified that studying the cell-cell correlations from single-cell data can allow the identification of cell-state transitions. However, this identification is likely obscured by noise, lineage and other sources of correlations. The project will involve simulating the dynamics of artificial gene-networks and identifying different sources of correlations between cells when they are going through state transitions (e.g. during differentiation).

This will eventually lead to developing theoretical tools to better understand the data associated with these transitions. The project will be a collaborative effort with Dr. Shaon Chakrabarti’s lab at NCBS.
