Using the techniques of electrophysiological recording and microinjection, Dr. Hua studies synaptic transmission, the means by which neurons communicate with each other. She is particularly interested in the speed of neuronal communication and theories on the signal processing capacity of neural networks. More recently, Dr. Hua started a project on the structural mechanism of human autism spectrum disorders. With several mutants of a Drosophila modal of human autism, she is trying to quantify the microstructural changes in the mutants’ neural synapses.
