028 – Roundtable: Neurotech vs Neuroscience

Vikash Gilja is an assistant professor at UCSD, where he researchers brain-machine interfaces. Dr. Gilja is an advisor to Paradromics. He holds a Ph.D. in computer science from Stanford University, an M.Eng and B.S. in EECS from MIT, and a B.S. in brain and cognitive sciences from MIT.

Rob Edgington is the head of AI at Paradromics. He holds a Ph.D. in brain-machine interfaces from UCL, and an M.Phys in physics from the University of Oxford.

Konrad Kording is a full professor at the University of Pennsylvania, where he works on data problems in neuroscience. He holds a Ph.D. in physics from ETH Zurich.

Top 3 Takeaways

  1. Basic neuroscience and neural engineering can and should co-evolve, much the same as physics and electrical engineering.
  2. More granular understandings from neuroscience help inform machine learning models applied in neurotechnology.
  3. Speech prostheses are a promising area for modern BMIs.
