Principal Investigator

Jonathan Viventi

Assistant Professor in the Department of Biomedical Engineering

Dr. Viventi’s research uses flexible electronics to create new technology for interfacing with the brain at high resolution over large areas. These new tools can help diagnose and treat neurological disorders such as epilepsy, and help improve the performance of brain machine interfaces.

Kay Palopoli

Hello, I’m Kay, an undergraduate senior. I’m majoring in Biomedical Engineering, with a Bioelectricity concentration, as well as earning a certificate in Genome Sciences and Policy. My main focus in lab is electrode testing. Specifically, I evaluate the long term reliability of µECOG arrays... More

Michael Trumpis

Ph.D. Student

I am an electrical engineer by training, with a fondness for timeseries analysis, inverse problems, machine learning, and open source science software. As a student of timeseries, I stumbled into electrophysiology over a decade ago and have never yet gotten over the wonder of the brain's... More

Ashley Williams

Ph.D. Student

My work focuses on designing novel electrode geometries and increasing the spatial density of electrode contacts of our flexible µECoG electrodes to obtain higher spatial resolution of brain activity. I am also exploring the use of materials such as Liquid Crystal Polymer and... More
