Dr. Wenfei Sun is an Assistant Professor of Medicine in the Division of Endocrinology at Stanford University. Originally from Zhejiang, China, Sun earned a B.S. from China Pharmaceutical University, an M.S. from Columbia University, and a D.Sc. from ETH Zurich. He performed his doctoral thesis with Prof. Christian Wolfrum, identifying novel molecular and cellular circuits that govern adipose tissue formation and function. From 2021–2025, Sun trained as a postdoctoral fellow with Drs. Steve Quake and Tom Südhof at Stanford, where he investigated the cellular and molecular basis of memory engrams, revealed astrocyte–neuron interactions during memory consolidation, and delineated neural circuits underlying socially transmitted food memory. Launching his laboratory at Stanford in 2025, Sun integrates neuroscience, metabolism, and genomics to explore how neural circuits regulate metabolic homeostasis and memory, with an emphasis on neuro-adipose communication and tool building that accelerates discovery.

Dr. Sun started his own lab at Stanford Endocrinology in September 2025 to explore how neural circuits regulate metabolic homeostasis and memory. Dr. Sun’s honors include the Pfizer Research Prize (2022), the Science & SciLifeLab Prize (2021), the ETH Medal (2020). 

Dr. Sun's lab explores neural circuits regulating memory and metabolism, integrating neuroscience and endocrinology to tackle cognitive decline and metabolic disorders.
