Yao Chen

Yao Chen, PhD, serves as Assistant Professor of Neuroscience at Washington University School of Medicine, where his laboratory pioneers research on neuromodulator dynamics in neural circuit function and behavior. His work bridges molecular neuroscience and systems-level analysis to investigate how signaling molecules like dopamine and acetylcholine regulate learning, sleep, and psychiatric disorders through precise spatiotemporal mechanisms.

Dr. Chen's academic foundation includes:

• PhD in Cell and Developmental Biology, Harvard University (2009)
• BA Honors in Natural Sciences, Cambridge University (2002)

The Chen Lab specializes in neuromodulation, sleep physiology, and learning mechanisms using cutting-edge methodologies including two-photon fluorescence lifetime imaging microscopy (FLIM), biosensor development, and electrophysiology in mouse models. Their research reveals how dynamic molecular signaling translates into behavioral outputs, with particular focus on protein kinase A pathways and neuromodulator receptor interactions. The lab's interdisciplinary approach integrates molecular, cellular, and systems neuroscience to address fundamental questions about brain function and dysfunction.

Analysis of Dr. Chen's publication record demonstrates consistent innovation in imaging technology development and neuromodulation research. His work shows progressive refinement of fluorescence-based techniques for tracking molecular dynamics across multiple time scales, from milliseconds to chronic adaptations. Key thematic threads include dopamine's role in learning circuits, sleep-related neuromodulator regulation, and the development of quantitative tools for biological signal analysis.

Dr. Chen's scientific contributions have been recognized through:

• NARSAD Young Investigator Award, Brain and Behavior Grant (2020-2022)
• Whitehall Foundation Research Grant (2019-2022)
• Ruth L. Kirschstein NRSA Individual Postdoctoral Fellowship from the NIH (2014-2016)
• Anuradha Rao Memorial Travel Award from the Rao family and Neuron (2009)
• Harvard University Certificate of Distinction in Teaching (2004)

The Chen Lab maintains active mentorship of graduate and undergraduate researchers, including PhD candidate Pingchuan Ma who recently completed his degree, and undergraduate Kane Goggans who presented research at the 2025 Spring Symposium. Current funding includes a Collaboration Initiation Grant with Hong Hu and Janet Sorrells for optimizing fluorescence lifetime analysis, and a Hope Center Pilot Award with Meng Wu investigating sleep regulation of the brain-gut axis across the lifespan. The lab is expanding through active recruitment of Staff Scientists, Senior Scientists, Postdocs, Research Technicians, and Programmers.

Operating within Washington University's Neuroscience Research Building, the Chen Lab fosters collaborative partnerships with engineering and data science departments through projects like the McKelvey School of Engineering collaboration on fluorescence analysis. The lab environment supports both fundamental discovery and translational applications, with recent summer programs engaging students Hanna, Shankar, and Carolyn in research projects that combine technical innovation with behavioral neuroscience.
