Next-gen Brain-Computer Interfaces

Research: Research

Next-generation brain-computer interfaces (BCIs) will transform the treatment of neurological and psychiatric conditions by directly measuring and regulating brain activity. Using advances in materials science and engineering we are building smaller, less invasive BCIs. Much of our work is based on magnetoelectric materials that facilitate efficient wireless power transfer and data communication to miniature implants. Based on these innovations we are building miniature brain stimulators, and networks of distributed implants to record and regulate brain states as therapies for brain conditions that are not responsive to traditional medications.

Translational Bioelectronics

Research: Research

Unlike pharmaceutical therapies that distribute small molecules to the entire body, bioelectronic devices can sense and stimulate activity in select nerves or brain regions to improve therapeutic precision and reduce side effects. To create tiny, wireless versions of bioelectronic devices we use magnetoelectric technologies that harvest power and data from magnetic fields that can penetrate deep into the body. Based on these technologies we are developing implantable networks of miniature devices that can support therapies including non-addictive treatments for pain, and less invasive cardiac pacemakers. 

We are also creating "hybrid bioelectronics" that combine the precision of electronic control systems with engineered cells that can produce chemical therapeutic biomolecules. By combining synthetic biology and bioelectronics we are creating improved therapies for cancer, obesity, and women's health.

NeuroAI

Research: Research

Artificial intelligence based on brain and behavior data can help create systems that mimic human and animal intelligence. Large quantities of neural and behavioral data are essential to train these technologies, providing the diverse, high-dimensional datasets needed to reproduce the output of complex biological systems. To this end we are creating scalable neural recording technologies and behavioral tracking pipelines, to collect brain and behavior data across species, enabling cross-species comparisons that can be used to develop neuro-inspired algorithms​.
