Dr. Divya Chander, MD, PhD,  is a physician, neuroscientist, and futurist who trained at Harvard, UCSF, UCSD, and the Salk Institute. She is currently the Chair of Neuroscience and Faculty in Medicine at Singularity University. She is also a Visiting Scholar in the Stanford Department of Medicine, Biomedical Informatics, and was a member of the Stanford Anesthesiology Faculty for 8 years.

In the operating room, Dr. Chander applies EEG technology to understand what human brains and the underlying networks look like when they lose and regain consciousness. She also has a precision medicine initiative focused on understanding genetic variability in responses to anesthetic drugs and brain oscillations. Her goal is to understand neural mechanisms of consciousness, as well as the evolution of human consciousness secondary to human augmentation. She is working on devices that read and write the brain (brain mapping, neuromodulation) and link to brain machine interfaces for diagnostic and therapeutic purposes.

Keynote Speaking:

• Neuroscience is on the cutting edge of decoding brains, making it possible like never before to peer into brains and hijack their circuitry. In this talk, Dr. Chander explores how old and new technologies make it possible to read visions and dreams, hack thoughts, and plant false memories. She also addresses how modern medicine and science make it possible to restore and enhance function to people who are paralyzed, opening the door to digital and robotic control with the human mind.
• Medicine / Healthcare is being transformed by exponential technologies that often are developed in the non-healthcare space. Dr. Chander explores how breakthroughs in 3D printing, robotics, artificial intelligence, stem cells, augmented and virtual reality, microfluidics, nanotechnology, and brain machine interfaces are pushing medicine into the realm of science fiction. New diagnostics, therapies, and even augmentation are considered, as well as their ethical implications.

• Bioethics has both the near and long-term implications for humanity and the biosphere. This has never been more true as we have gained the ability to rewrite both the genetic and the neural code, fundamentally changing what it means to be human. The ability to implant, read and write functions to humans leaves us vulnerable to losing our privacy, or even being hacked and manipulated. This talk explores the ethical implications of the technology we have developed, which is exploding at an exponential rate, and considers some new solutions.
