Lorenzo Turicchia
Lorenzo Turicchia’s main research interests are in nonlinear signal
processing, machine learning, and bioelectronics. In 2002
he joined the Analog VLSI and Biological Systems group at MIT.
His work
has included research on cochlear implants (bionic ears) for the hearing
impaired, visual prostheses for the blind, speech
prostheses for individuals with severe communication disabilities, automatic
speech recognition in noise, and wearable medical devices.
He is
currently working on (1) robust techniques for the recognition of speech,
speaker, and language in noisy environments; (2) bioelectronics for wearable
and implantable medical devices; and (3) neural decoding techniques for neural
prosthetic devices for the paralyzed. He is an Associate Editor of the IEEE
Transactions on Information Technology in Biomedicine (T-ITB)
and serves on the program committees of several technical conferences.
