Karen Ashe

Karen K. Hsiao Ashe is a professor at the Department of Neurology and Neuroscience at the University of Minnesota (UMN) Medical School, where she holds the Edmund Wallace and Anne Marie Tulloch Chairs in Neurology and Neuroscience. She is the founding director of the N. Bud Grossman Center for Memory Research and Care, and her specific research interest is memory loss resulting from Alzheimer's disease and related dementias. Her research has included the development of an animal model of Alzheimer's.

In July 2022, concerns were raised that certain images in a 2006 ''Nature'' paper co-authored by Ashe and her postdoctoral student Sylvain Lesné were manipulated. In May 2023, the ''Star Tribune'' reported that Ashe was using new techniques to re-do the work reported in the 2006 ''Nature'' study, this time without Lesné, and that she stated "it's my responsibility to establish the truth of what we've published". The new article was published in March 2024. The 2006 article was retracted in June 2024; all of the original authors except Lesné agreed with the retraction. Provided by Wikipedia
