Our lab studies the cellular mechanisms of injury and stress responses in the heart. We are particularly interested in the innate immune system and how inflammation impacts wound healing, fibrosis, and tissue remodeling in beneficial as well as adverse ways. We use the mouse as our primary model, which allows us to interrogate gene functions and signaling pathways, perform genetic lineage tracing, and mimic complex cardiovascular pathology in a mammalian system. Our goal is to understand the regulatory mechanisms of cardiac wound healing and discover novel approaches to repair or even rejuvenate the damaged heart. Our approach, first and foremost, is driven by a shared lab culture of teamwork, discovery, and high-quality science.

Ilaria moved to Colorado in 2018 from New York City after receiving a B.S. in mechanical engineering from Columbia University. Since then, she conducted clinical research for the Emergency Department of Children's Hospital Colorado while completing her premedical coursework, and she is now excited to bring both engineering and clinical perspectives to the lab.
