Dr Chenghao Chen is a Postdoctoral Fellow at the University of Washington, (Seattle, US) in the lab of Dr. John Tuthill, he is also a visiting scientist at Janelia Research Campus, in the lab of Dr. Gwyneth Card’s lab. During his postdoctoral work, he uses Drosophila leg as a research model to understand the organization and function of neural circuits for proprioception, the internal sense of body movement and position. His recent work (Chen et al., Current Biology, accepted) revealed how mechanosensory signals from peripheral sensory organs (proprioceptors) converged in the second-order neurons in Drosophila ventral nerve cord, the invertebrate analog of the spinal cord. Prior to this, he earned his Ph.D. at the University of London (London, UK) in Prof. Ralf Stanewsky’s laboratory, where he used Drosophila genetics to study molecular mechanisms underlying synchronization of circadian clock by cycling temperature. One of his work identified a putative thermo receptor in leg chordotonal organ, namely ‘IR25a’, is required for molecular and physiological resetting biological clock to temperature.
