About
Xi Chen is a pioneering researcher at the intersection of neuroscience and biomedical engineering, with a particular focus on developing innovative tools for non-invasive neural modulation. Chen's most celebrated contribution is the development of fully implantable upconversion microdevices capable of achieving tetherless, near-infrared control of brain activity in behaving animals — a landmark 2017 study that has accumulated 95 citations and represents a significant leap forward in optogenetics and neural interface technology. This work addresses one of the field's most persistent challenges: enabling precise, wireless control of neural circuits without physically constraining the subject. By harnessing the unique optical properties of upconversion nanoparticles to convert near-infrared light into shorter wavelengths capable of activating light-sensitive proteins, Chen's approach offers deeper tissue penetration and greater experimental freedom than conventional optogenetic methods. The implications span fundamental neuroscience research, behavioral studies, and the longer-term development of next-generation neuroprosthetics and therapeutic devices. Chen's research exemplifies how materials science and engineering innovation can transform our ability to probe and understand the living brain, making their work essential reading for students and researchers in neural engineering and translational neuroscience.
