Sleep, learning and memory are complex phenomena that are of great importance for survival. Although the quantity and quality of sleep have a profound impact on learning and memory, the exact mechanisms are not known. Daily learning experience was suggested to be helpful to improve sleep. However, the interaction mechanism between the two systems is rarely understood. Dysfunctions in sleep and cognition are usually associated with neurodegenerative disorders, such as Alzheimer’s disease. To investigate the molecular and cellular basis of the interaction between sleep and memory, we will employ fruit fly Drosophila melanogaster as the animal model and apply multidisciplinary approach, including behavioral, genetic, anatomical and imaging techniques. We will also take the advantage of the platforms of BCBDI to study the same questions through cross-species verification.

Positions available in the Liu Lab at SIAT
The lab has open positions for ambitious and highly motivated postdoctoral research fellows, a research associate/assistant, and (joint) graduate/master students to investigate the molecular mechanisms and neural circuits of sleep and cognition as well as exploring novel biomarkers for the diagnosis and prognosis underlying Alzheimer’s disease. Candidate’s CV and two referees’ contact information should be sent to
