My research aims to give abilities back to people living with a neurological injury or disease. Throughout my time as a postdoc at Caltech, I developed a new, less invasive method for high performance brain-computer interfacing or “BCI” based on ultrasound.
I’m a Scientist at Convergent Research, BCI Strategist at AE Studio, and a visiting affiliate at Caltech. I trained as an NSF graduate research fellow in mechanical and aerospace engineering, but got my start in solid state physics and mechatronics.
