Senior Fellow and Research Professor
HHMI Janelia Research Campus and Johns Hopkins Biomedical Engineering
Tim Harris is a Group Leader and Senior Fellow at the HHMI Janelia Farm Research Campus in Ashburn, VA and a Research Professor at Johns Hopkins University Department of Biomedical Engineering.  After his Ph.D. from Purdue University, Tim spent the following 18 years at Bell Labs, Murray Hill, NJ.  While at Bell, his work included high sensitivity fluorescence, the characterization of single quantum dots using fluorescence Near-Field Microscopy.  In 1996 Harris moved to Seq Ltd. a small biotech startup in Princeton, NJ, where he led the development of high throughput multicolor confocal microscopy. Harris moved to Helicos Biosciences in January 2004 as the founding technical employee where his team reported the first single molecule DNA sequencing.  In 2008 Tim moved to the HHMI Janelia Research Campus.  Among others, he initiated a project, now called Neuropixels, jointly funded by HHMI, The Allen Institute for Brain Research, Gatsby Charitable Foundation, and the Wellcome Trust.  More than 14,000 probes have been shipped to more than 1,000 labs since January, 2018. At Johns Hopkins, with funding from the NIH BRAIN Initiative, the Harris lab is finalizing the family of recording probes, small enough for more than 6,000 channels in a freely moving mouse.
