# Brad

I'm currently a doctoral student at UC San Diego, conducting research on the neural network properties of memory formation. Using a mixture of neurobiological and computational programming tools, I study and model memory and synaptic potentiation.

Professional Interests: neural networks, synaptic potentiation, memory, learning, brownian motion, particle diffusion, particle tracking
