Chiang Ann-shyn

Chiang Ann-shyn (Chinese: 江安世; born 1958) is a Taiwanese neuroscientist recognized for his pioneering contributions to Drosophila connectomics and the mapping of memory-related neural circuits. He currently serves as the Honorary Director of the Brain Spatiomics Center at China Medical University Hospital.

Education

Chiang obtained a Bachelor of Science in entomology at National Chung Hsing University in 1981, earned a master's degree in plant pathology and entomology from National Taiwan University, then moved to the United States, where he completed a doctorate in entomology at Rutgers University in 1990. Chiang's doctoral dissertation was titled Developmental Regulation of Juvenile Hormone Biosynthesis in Female Cockroaches. Upon completing his postdoctoral research under Coby Schal at Rutgers in 1992, Chiang returned to Taiwan.

Career

Chiang began his teaching career as an associate professor at National Tsing Hua University, and was promoted to a full professorship in 1997. He led NTHU's Institute of Biotechnology from 2002 to 2008, and since 2004, has been director of the NTHU Brain Research Center. In 2007, Chiang was appointed to a Tsing Hua Chair Professorship, which became a Distinguished Tsing Hua Chair Professorship and the deanship of the NTHU College of Life Sciences in 2014. He has held an adjunct professorship at National Central University since 2005, an adjunct chair professorship at Kaohsiung Medical University since 2014, and an adjunct distinguished chair professorship at China Medical University since 2016. Adjunct Roles and advisory appointments at numerous prestigious institutions, including Academia Sinica, the Kavli Institute for Brain and Mind, Cold Spring Harbor Laboratory, the Ministry of Education as a Tenured Chair Professor, National Health Research Institutes, and the National Synchrotron Radiation Research Center, among others.

Research and Achievements

Chiang is a leader in the field of connectomics, focused on understanding how the brain processes information and stores memory. His notable achievements include:

  1. Odor Representation: Discovered neuronal temporal identity and mechanisms for gating CO2 information (Cell, 2006; Cell 2007; Science, 2013; Science Advances 2025).
  2. Long-Term Memory: Identified that LTM requires protein synthesis in specific subsets of neurons (Science, 2012; Cell Reports, 2023; Current Biology, 2024; PNAS 2025; Cell Reports, 2026).
  3. 3D Fly Brain Database: Developed the first brain-wide wiring map at single-neuron resolution, aiding sensory circuit analysis (Current Biology, 2011; Nature Communications, 2015).
  4. Tissue Clearing Technology: Created FocusClear, the first tissue-clearing reagent compatible with GFP for high-resolution 3D imaging at 30 nm resolution (Nature Communications, 2019).
