Tim Harris is a research professor, sharing his time between the Johns Hopkins Department of Biomedical Engineering and the JHMI Janelia Research Campus. He is the originator of the project that produced the Neuropixels Si probe for extra cellular recording in animals, mostly mice and rats but including more than 20 species. At Johns Hopkins, Tim has pursued this thread to produce a more advanced technology, Neuropixels NXT. The small 1536 channel probes now allow recording 10-20,000 neurons in rodents and 30-50,000 neurons in non-human primates. They are now moving from producing the probes to exploiting this technology for brain wide recording, including brain changes generated by psychedelics, learning, and disease.
He received a BS in Chemistry at California Polytechnical State University, San Luis Obispo, and a PhD in Analytical Chemistry at Purdue University.
