Xu Liu, a newly appointed assistant professor of neurobiology at
Northwestern University best known for his work manipulating mouse memories
using optogenetics, has died. He was 37.
A native of Shanghai, Liu’s early interest in science stemmed from his
collecting centipedes, beetles, and locusts as a child. He earned an
undergraduate degree in biology at Fudan University in Shanghai and
completed his doctoral research, focused on fruit fly memory, with Ron Davis
at the Baylor College of Medicine in Houston, Texas.
As a postdoctoral fellow in the laboratory of Susumu Tonegawa at MIT, Liu
and graduate student Steve Ramirez used optogenetic techniques to identify
the neurons involved in encoding fear memories in mice. In a follow-up study
, Liu and Ramirez used their understanding of fear memory formation to
create a false fear memory of a harmless location. The work generated great
scientific and public interest. The team’s two TED talks on this work have
generated nearly 1 million views online. Liu and Ramirez were awarded the
2014 Smithsonian American Ingenuity Award and were runners-up for Science’s
Breakthrough of the Year in 2014. Later research replaced negative memories
with positive ones.
“For me, what made [Liu and Ramirez] successful was their fearlessness,”
Sheena Josselyn of the Hospital for Sick Children in Toronto told
Smithsonian last year. “They applied the best sort of mind power.”
“We hope that our work can lay the foundations for potential future
treatments for memory-related disease,” such as Alzheimer’s disease and
PTSD, Liu told Smithsonian.
Liu officially started at Northwestern this month. “Xu was much more than
an accomplished and gifted scientist. His colleagues have noted his
generosity, his mentorship of students, his genuine friendliness, and his
sense of humor,” a release from Northwestern’s neurobiology department
noted. “This is truly a great loss for . . . the larger neuroscience
community at Northwestern and worldwide.” | k****e
