James H. Marshel

James H. Marshel is an **Assistant Professor of Neuroscience** at **Weill Cornell Medicine** and **Lab Director** of the **Laboratory for Systems Neuroscience of Vision** at **Burke Neurological Institute**. His research focuses on understanding neural circuit mechanisms underlying visual perception and sensory learning. He holds a Ph.D. in Neurosciences from the University of California, San Diego, and completed postdoctoral training at Stanford University under Karl Deisseroth, pioneering optogenetic and neural circuit mapping techniques.

Education:

• B.A., Molecular and Cell Biology, University of California, Berkeley
• B.A., Psychology, University of California, Berkeley
• Ph.D., Neurosciences, University of California, San Diego
• Postdoctoral Fellowship, Bioengineering, Stanford University

Research Interests:

• Neural circuit dynamics in visual systems
• Optogenetic manipulation of neural ensembles
• Large-scale in vivo imaging and stimulation techniques
• Causal links between neural activity and perception/behavior

Lab Focus: The Marshel Lab develops tools like multiphoton holography and advanced optogenetics to map and perturb neural circuits with single-cell precision. They study how neural connectivity and activity patterns drive visual perception and learning.

Grants & Mentoring: Dr. Marshel mentors postdoctoral fellows, technicians, and students. Current openings include roles in systems neuroscience, engineering, and lab management. His work is supported by federal and private grants.

Labs/Teams: Associated with the **Marshel Lab**, part of the **Burke Neurological Institute**, and affiliated with **Weill Cornell Medicine**. Collaborates widely in neuroscience and engineering communities.
