About Morgan Levine:
Morgan Levine was previously a tenure-track Assistant Professor in the department of Pathology at Yale University where she ran the Laboratory for Aging in Living Systems. In 2022, she was recruited to join Altos Labs as a Founding Principal Investigator at the San Diego Institute of Science. She currently leads a research group at Altos Labs working at the intersection of bioinformatics, cellular biology, complex systems, and biostatistics with the overall goal of understanding the molecular trajectories aging cells, tissues, and organisms take through time.
