Keva Li received her B.S. in Molecular and Cellular Biology from Johns Hopkins University in 2021. She previously worked in the Mechanical Engineering of Wet-materials (MEOW) Laboratory of Dr. Yun Chen. Her undergraduate research focused on the role of viscosity in basic cell behavior and function through cytoskeleton remodeling. In 2021, Keva joined the Laboratory of Cardiovascular Science (LCS) under the supervision of Dr. Edward G. Lakatta. Her research focuses on the sinoatrial node (SAN), the natural pacemaker of the heart. She studies the heterogenous SAN population, with a focus on cardiac telocytes, and exosomes released from SAN cardiac fibroblasts. She also studies photobiomodulation or low-level laser therapy on cell proliferation. Her research investigates the consequences of cardiac-directed expression of AC8, adenylyl cyclase type 8 and age-associated changes.
