Ben is an MD-PhD student pursuing his
MD in the Health Sciences and Technology
Program at Harvard Medical School, as well as
his PhD in Electrical Engineering at MIT (Analog VLSI and Biological Systems
Group, Research Laboratory of
Electronics). He received his AB in Physics and Mathematics and AM in
Physics from Harvard in 2003, and an MSc in Mathematical Biology from Oxford in 2004. Ben is interested in designing and
neurosurgically implanting electronic interfaces with the brain and nervous
system, such as neural prosthetic devices for the paralyzed and disabled,
which can repair and augment neurologic function. His current work is on
algorithms and ultra-low-power electronic architectures for decoding
neural signals in the context of fully implantable brain-machine
interfaces.
