Episode 6 - Josh Mallinson: Computers that think

26 January 2024

Computers are incredible at logical processing, but could they ever think like humans? Josh Mallinson鈥檚 work in neuromorphic computing is helping to shed light on how brains work 鈥 and how computers might one day follow suit. In Season 2, Episode 6, Josh Mallinson talks about computers that think on UC Science Radio. Listen up.

HOW TO APPLY

In this episode

0.47听Our research is about neuromorphic computing and specifically using percolating nanoparticle networks

2.15聽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听We want to use these chips that have these brain-like dynamics to try and create hardware versions of artificial neural networks

4.15聽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聽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聽We want to take the inspiration from nature's approach to information processing, and try and replicate that.

6.02听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聽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聽I would like聽my research to contribute towards humanity's understanding of intelligence.

After completing his undergrad at UC in 2012聽Josh Mallinson聽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.

鈥淔or me, the most enjoyable aspect of my work is developing and testing theories. I see some strange behaviour in the data I鈥檝e 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鈥檝e ever had.鈥
