Single cell gene molecular profiling has demonstrated that cell classification requires more than a simple collection of markers. Current approaches do not account for the dynamic nature of cell states and inherent variation in cell types. This is especially...
Our laboratory’s research focuses on understanding (1) how cells measure levels of available nutrients and (2) how cells adapt to changes in nutrient supply to control metabolic homeostasis. Our studies have primarily centered on changes in cholesterol and oxygen...
Background and Summary: Epithelial cells in a tissue live a crowded life connected to, and interacting with, other cell types, the extracellular matrix, and diverse signaling molecules. A fundamental question in biology is: how do the constituent cells of an...
Understanding how the information in the genome is utilized is one of the central questions in modern biology. It has become clear that a critical level of gene regulation occurs through the chemical modification of both the DNA itself...
Our laboratory studies the basic molecular mechanisms of programmed cell death, an evolutionarily conserved process to eliminate cells. Because these pathways normally contribute to the millions of cell deaths that occur per day per individual, defects in cell death...
Mechanisms of gradient sensing and chemotaxis are conserved in mammalian leukocytes and Dictyostelium amoebae. Both cells use G protein linked signaling pathways. PH domains specific for PtdIns(3,4)P2 and PtdIns(3,4,5)P3 bind to the membrane at the leading edge of the...
The overarching goal of our laboratory is to characterize a novel endogenous protective signaling network of mammalian cells and tissues to provide insight into the molecular mechanisms underlying disease and to highlight novel therapeutic avenues. Cells and tissues respond...
Research Interests: My laboratory’s research is focused on understanding how multi-subunit assemblies use ATP for overcoming topological challenges within the chromosome and controlling the flow of genetic information. We are particularly interested in developing mechanistic models that explain how...
