Scientific Interests
Dr. Hilary Coller's current research focus is on understanding the molecular basis of quiescent cells (cells in a temporary non-dividing state). While the commonly held perception of quiescence is as a sleepy or default state, her research instead suggests that quiescence is an active and highly regulated process. Using sophisticated technologies and computational approaches to understand the cellular networks that underlie quiescence, Coller's lab is applying next generation sequencing, mass spectrometry proteomics and mass spectrometry metabolomics to generate high-quality datasets defining the characteristics of proliferating and quiescent cells. They have also developed computational and algorithmic approaches for analyzing and interpreting these datasets. Coller's specific research goals include translating these findings to understand the changes that occur during tumor dormancy as well as utilizing similar approaches to understand the changes that occur when fibroblasts become activated to cancer-associated fibroblasts.
