Alexandra McCubbrey, PhD

Assistant Professor


2014: University of Michigan, PhD, Immunology
2008: Kalamazoo College, BA, Biology


Dr. McCubbrey has been studying lung macrophages and the engulfment of apoptotic cells (efferocytosis) since 2008. After receiving a K99/R00 from the NHLBI to study macrophage metabolism in response to efferocytosis, she started her research lab at National Jewish Health in 2020. Her laboratory works to understand mechanisms of tissue repair and fibrosis through the study of lung phagocytes and their engulfment of apoptotic cells. Outside of lab she enjoys cooking, hiking, and working on house projects with her wife. Her phone is full of pictures of food and her cat.

Peter Moore, MD



2021: Fellowship, Pulmonary Sciences and Critical Care Medicine, University of Colorado Anschutz Medical Campus
2016: Residency, Internal Medicine, University of California San Francisco
2012: MD, University of Colorado Anschutz Medical Campus
2007: BA, Molecular, Cellular, and Developmental Biology, University of Colorado Boulder


Dr. Moore began studying macrophages under the mentorship of Dr. McCubbrey and Dr. Bill Janssen in 2019 as during his pulmonary sciences and critical care medicine fellowship. His research has focused on characterizing interstitial macrophage heterogeneity during homeostasis and acute inflammation. He is also interested in understanding the roles of the coagulation/fibrinolytic system during inflammation. Outside of work he enjoys cooking vegan food, skiing, and spending time with his wife, daughter and Labrador retriever.
