Dr. Johnson studies the dynamical nature of human memory to understand how we can flexibly update our autobiographies as we amass experiences from childhood through adulthood. As a BRAIN Initiative investigator, she aims to map the neurophysiological substrates of memory formation and maintenance from the level of neuronal ensembles in single trials to that of large-scale brain dynamics across individuals. To do this, she utilizes invasive intracranial EEG and microwire recordings in individuals engaged in working and declarative memory tasks, as well as noninvasive scalp EEG. Outcomes of this research will advance basic science and be applied to improve quality of life. Dr. Johnson holds a PhD from the University of California, Berkeley, and a BA from the University of Chicago. She is also a Science Mentor for the journal Frontiers for Young Minds.
