معرفی
Scott Waddell is Professor of Neurobiology and Wellcome Principal Research Fellow at the University of Oxford's Centre for Neural Circuits and Behaviour (CNCB) within the Medical Sciences Division. He leads an active research group investigating neural mechanisms of memory, motivation, and behavioral individuality in Drosophila (fruit flies).
Waddell's research focuses on understanding how neural circuits encode, consolidate, and retrieve memories, with particular emphasis on:
- Neural circuit mechanisms of memory-directed behavior
- Motivational control systems that gate memory expression
- Dopaminergic reward pathways and their role in memory formation
- How nutrient sensing influences memory persistence
- The neural basis of behavioral individuality
His laboratory has made several groundbreaking discoveries, including identifying specific neurons required for memory, demonstrating functional subdivision of mushroom body neurons for memory consolidation versus retrieval, and discovering how motivational states like hunger control memory expression through dopaminergic signaling. The group employs sophisticated techniques including optogenetics, two-photon microscopy, and advanced behavioral paradigiments to investigate these questions at cellular resolution.
Waddell's work has revealed striking mechanistic similarities between flies and mammals in reward processing and memory mechanisms, while also uncovering unique aspects of Drosophila neurobiology. His research demonstrates that fundamental principles of neural circuit operation are conserved across species, making Drosophila a powerful model for understanding intelligence in all animals.
Among his notable honors are:
- Wellcome Principal Research Fellow (2016-present)
- Wellcome Senior Research Fellow (2011-2016)
- Member of EMBO
- 2014 Liliane Bettencourt Prize for the Life Sciences
Waddell supervises multiple PhD students and postdoctoral researchers who contribute to the lab's collaborative and interactive research environment. His group is currently working on understanding small neural circuits that support memory and direct behavior, with the goal of achieving cellular-level understanding of neural mechanisms of behavioral control.
