UC Science Radio Season 2: Episode 6
Josh Mallinson: Computers that think
Computers are incredible at logical processing, but could they ever think like humans do? Josh Mallinson’s work in neuromorphic computing is helping to shed light on how brains work – and how computers might one day follow suit.
Neuromorphic computing is a field of study that aims to make physical systems which process information the way brains do.
Josh Mallinson’s PhD goes beyond investigating physical substrates and electrical pathways to furthering our understanding of consciousness itself. With potentially ground-breaking outcomes in terms of energy efficiency, neuromorphic computing is definitely a field worth learning more about. Josh Mallinson enlightens us in this episode of UC Science Radio.

0.47 Our research is about neuromorphic computing and specifically using percolating nanoparticle networks
2.15 There's many pathways which the current can flow through that network and there are some pathways that just aren't quite completed, so there's gaps. So in those gaps is where the interesting physics takes place.
3.29 We want to use these chips that have these brain-like dynamics to try and create hardware versions of artificial neural networks
4.15 We want computers that are intelligent, that can make decisions, that can recognize patterns and predict what's about to happen. And so we basically want our computers to do things that humans are good at now.
5.00 The most advanced artificial intelligent systems use megawatts of energy. Whereas the biological counterpart, the human brain, only needs a sandwich and a glass of water to run
5.15 We want to take the inspiration from nature's approach to information processing, and try and replicate that.
6.02 The more we can reduce the amount of power needed by computing hardware in the world, the more we can reduce those negative effects of generating that power.
6.28 I didn't decide - "I really want to work on neuromorphic computing." It's one of those things where it was an opportunity that presented itself to me.
8.01 I would like my research to contribute towards humanity's understanding of intelligence.

Meet our speakers
After completing his undergrad at UC in 2012 Josh Mallinson worked in the construction industry for four years. In 2016 he decided to come back to UC to further his learning. He contacted one of his favourite lecturers to see what projects he was working on, which eventually led to his present PhD topic in neuromorphic computing.
“For me, the most enjoyable aspect of my work is developing and testing theories. I see some strange behaviour in the data I’ve collected, I develop a theory to explain it, and then devise a way to test the theory. Proving a theory correct is one of the most rewarding experiences I’ve ever had.”
