Daniel Freeman

Dr. Daniel Freeman is a technical staff member in the Advanced Materials and Microsystems Technologies Group at MIT Lincoln Laboratory. His research focus is on the neurophysiological features required to elicit conscious perception of sensory inputs, such as vision or hearing. This work includes human testing with transcranial ultrasonic neuromodulation, as well as comparative anatomy aimed at identifying common structures and neural networks across vertebrate species that mediate conscious perception. Freeman also contributes to a variety of national security programs across the lab.    

Prior to joining Lincoln Laboratory, Freeman was a technical staff member at Draper Laboratory, where he developed a submillimeter, inductively powered neural stimulator and developed electromagnetic models for MEMS sensors and diamond vacuum transistors. Additionally, Freeman worked at Draeger/Siemens Medical, where he designed low-noise analog electronics for patient monitors.

Freeman received his PhD degree in biomedical engineering from Boston University in 2008, followed by postdoctoral fellowships at Harvard Medical School and MIT, where he developed novel methods of neural stimulation for retinal implants.
