research overview
Cancer treatments lead to favorable outcomes only in a subset of patients partly due to significant heterogeneity in tumor cells. Towards developing improved and personalized treatments, our research aims to characterize the heterogeneous populations of interacting cells in the tumor microenvironment and their spatio-temporal dynamics and dysregulated circuitry using an unsupervised approach.
Recent advances in single-cell genomic and multiplexed imaging technologies have empowered us to profile heterogeneous phenotypes at the resolution of individual cells and in the context of the tissue microenvironment. However, analysis of single-cell data involves major statistical challenges. Our interdisciplinary approach involves developing novel machine learning methods to address the statistical and computational challenges inherent to high-dimensional single-cell and imaging data.
By integrating single-cell multi-omics and imaging data using probabilistic modeling and deep learning approaches, we aim to infer intercellular interactions and dysregulated programs in the tumor microenvironment. We are also interested in developing statistical models for studying the temporal dynamics of cell populations and their underlying circuitry in response or resistance to immunotherapies.
Ultimately, these interpretable frameworks applied to various cancer systems can guide and improve therapies by accounting for diversity and plasticity of cells.
