Biography

I am a physicist specializing in nanomaterials and neuromorphic devices. I'm originally from the US, and grew up in Los Alamos, home of the atomic bomb.

In addition to research and teaching, I run Bright Club in Ireland, the variety night for lateral minds. I also appear frequently on Futureproof, the Newstalk science radio show, and give lots of public talks.

Research Interests

My focus is on electronics made from nanomaterials, which behave differently than bulk materials. My lab creates nanoelectronic devices, from nanowires or nanocrystals, and then examines their electrical behaviour and their interaction with light. Nanomaterials often act as memristors, whose electrical conductivity changes depending on measurement history. This makes nanomaterials ideal for memory applications.

I am especially interested in 'neuromorphic' electronics, whose function in some way mimics the synaptic connections between neurons in the brain. To this end I collaborate not only with engineers and chemists, but also with neuroscientists. I am a co-PI in the CÚRAM medical device centre.
