three spheroid thunderlillies


We aim to create new technology and techniques for studying physical and neurological trauma, using sensors, heaters, LED and arrays. 

Complex three-dimensional cultures, known as spheroids, organoids, and assembloids, have been developed to recreate structural features of human neuronal tissues in vitro not adequately modelled by two-dimensional cultures. The goal of this project to is to create new technology and techniques for studying electrophysiology and neurotrauma with three-dimensional cultures. This includes three-dimensional multi-electrode arrays, oxygen sensors, heaters, and LEDs. We use these in combination with our in-vitro three-dimensional neural cultures and devices to study neurotrauma and electrophysiological behavior in networked neurons.
