We study inflammatory injury, lung injury, cellular heterogeneity, tissue regeneration, the blood brain barrier and neurodegeneration. A major focus of our laboratory is to develop novel computational approaches and analyze RNA-Seq data as well as single cell RNA-Seq data to identify novel mediators of inflammation, injury and regeneration.

Research Currently in Progress

Research Interests

1. Host defense, inflammation and tissue injury: What are the mechanisms regulating the immune response to a bacterial or viral infection and how does a dysregulated immune response cause injury to the tissue? What role do blood vessel endothelial cells play in regulating the immune response? How do macrophages choose their fate to transition into pro-inflammatory and pro-repair cells during an acute inflammation response? What role does the cellular metabolism play in regulating inflammation and immunity?
2. Stem cell differentiation and tissue regeneration: What are the environmental and metabolic cues regulating the differentiation of pluripotent stem cells into mature cardiovascular cells? How do we mature newly differentiated cardiovascular cells so that they can replace diseased tissue? Can we activate endogenous transcriptional programs in the adult vasculature to initiate tissue repair and regeneration?
3. Blood brain barrier and Neurodegeneration: How does blood brain barrier dysfunction promote inflammation and progression of neurodegenerative diseases such as Alzheimer’s Disease? Can we model the blood brain barrier and its dysfunction using brain organoids derived from human induced pluripotent stem cells? Is there a transcriptomic signature of the brain vasculature which promotes neurodegeneration?
4. Cancer metabolism: How does dysregulation of metabolism in tumor cells and in the tumor blood vessels promote tumor growth? What are the interactions between tumor cells and tumor blood vessels which promote tumor metastases or the entry of metastatic cells into the tissue?
5. Computational biology: Can we develop novel computational algorithms to understand signaling networks in cells and their responses during stress, injury and repair? Are there novel approaches to analyze single cell RNA-Seq data in a biologically meaningful manner that reveals the complexity and heterogeneity of tissues?
