Cristina Alberini is a professor of neural science at New York University whose research focuses on the identification and characterization of the biological mechanisms that accompany long-term memory formation, storage and retrieval. In doing so, she probes the nature and functions of genes and proteins that play a critical role in long-term memory formation in different brain areas, and she looks at how those areas evolve over time. She also looks at the biological mechanisms that accompany memory reorganization after retrieval. She believes that understanding the biological changes that underlie the formation and storage of long-term memory is important for developing strategies that change memory strength. This may lead to therapeutic approaches for memory loss associated with aging, including Alzheimer’s. It may also help with memory disorders due to pathogenically strong memories, such as those occurring in post-traumatic stress disorder (PTSD).
