Our motivation

The human body is comprised of a large collection of diverse cell types, each providing a specialized and context-specific function. The advent of high-throughput single-cell technologies have enabled unbiased categorization of cells from diverse developmental and diseased processes.

In our work we seek to use single-cell tools to understand: i) how cells vary through time, ii) how these differences affect cellular decisions and iii) how transcription factors affect the activity of regulatory elements and, in turn, how these elements lead to functional differences in expression.

Our lab seeks to address these challenges by developing biological tools to measure chromatin dynamics in single-cells. Further, we use these tools to study chromatin alterations in adult stem cells across normal, ageing and cancer tissues in effort to uncover new mechanisms of gene regulation and their contribution to disease.

Developing new technologies

Previously, we developed RNA-MaP and Assay for Transpose Accessible Chromatin (ATAC-seq), which has become a popular method to measure genome-wide chromatin accessibility. We adapted this method to profile the epigenomes of single-cells (scATAC-seq), and are are actively developing technologies to improve the quality and throughput of these measurements, as well as integrating scATAC-seq with other single-cell ‘-omic’ measurements.

Computation for inferring ‘causative’ gene networks

We develop computational methods to support novel technologies, for example methods for high-content image-analysisnucleosome calling and single-cell epigenomics. The new computational methods we are developing focus on integrating ensemble and single-cell ‘-omics’ data to infer causative gene networks. Such networks will seek to model governing cis and trans effectors of dynamic cell function.

Epigenomic regulation of cell fate decisions

We study leukemia and early human hematopoiesis and welcome new collaborations into other systems. Previously, we used our novel experimental and computational methods to understand molecular effectors that govern hematopoietic cell fate. We use these findings to better understand the ontogeny of Acute Myeloid Leukemia (AML).
