Xuqing Feng received a bachelor’s degree in life sciences from Peking University in 2022 and is currently a PhD candidate in neurobiology at Peking University, working in Xitong Liang’s laboratory. Xuqing’s doctoral research investigates the neural mechanisms underlying colour-changing behaviour in cephalopods, with a focus on cuttlefish. By integrating electrophysiological stimulation, calcium imaging and neural circuit tracing, Xuqing aims to clarify how brain regions control chromatophores, the basic units of cephalopod camouflage. He hopes to join the summer course to deepen their understanding of motor circuit organisation, neural coding and neuroinformatics tools for analysing complex neural and behavioural data.
