Deciphering Mechanisms of Genome Mis-folding In Cancer
Our lab deploys data-rich experimental techniques to elucidate the role of genome mis-folding in controlling oncogenic gene expression programs. Specifically, we are interested in moving beyond the status quo to understand how oncogenic subversion of lineage-determining transcription factors set topology of cancer genome. To tackle this question, we combine genomics and super-resolution imaging and focus on investigating molecular mechanisms of genome mis-folding in breast and blood cancers. These mechanistic studies aim to identify precise epigenetic vulnerabilities of cancer cells and guide treatments disrupting cancer cells’ transcriptional addiction.

Determining Epigenetic Mechanisms Of Resistance To Targeted Therapies
Targeting oncogenic drivers of cancers commonly leads to drug resistance. Mechanisms of acquiring resistance to oncology drugs mostly remain unknown, partly due to the limitations of population-based assays in elucidating heterogeneity of drug-naive and complexity of drug-induced tumor evolution. Using single-cell genomics and imaging, we study how heterogeneity and plasticity of transcriptional dependencies confer resistance to targeted therapeutics such as Notch inhibitors.

Innovating Computational Methods To Enable Cancer Discovery
Our lab innovates statistical and machine learning approaches to accelerate discovery of novel therapeutics and biomarkers by elucidating complexity and heterogeneity of tumors. Recently, we have developed a computational ecosystem for mapping molecular and spatial heterogeneity in tumors. As part of the Center for Personalized Diagnostics, we also mine cancer patient genotypic/phenotypic data to improve patient health. patient health.

Cancer is typically considered a genetic disease. However, recent progress in our understanding of epigenetic aberrations in cancer has challenged this view. Overarching goal of our lab is to understand epigenetic mechanisms of transcriptional addiction in cancer and exploit this information to advance cancer therapeutics.
To pursue this objective, we use cutting-edge chromatin conformation capture, high-content imaging, single-cell epigenomics, functional genomics, and combine these technologies with our expertise in computational sciences to systematically explore: i) how epigenetic control of gene expression is disrupted in cancer, ii) why transcriptional addiction can develop, and iii) how heterogeneity and plasticity of transcriptional dependencies enable drug resistance.
