1. Where did 'Nanogirl' come from?
I have a horrendous fear of public speaking. Before I speak, I'm usually dry retching with nerves. I call it my "super weakness". Everybody has that thing you're not very good at and you can just ignore it or you can say "this is holding me back, how do I work at this?". So I took a lot of courses and an acting coach told me, "just create a personality that's not you but who you want to be like and put that person on stage, because then it's not a personal attack if you get it wrong". The name came from kids when I was doing school visits talking about nanotechnology and making "nano nano" jokes. They called me Nanogirl.
2. How do you think Nanogirl is seen by other scientists?
I'm sure I've lost all credibility in the academic community by targeting children but I don't care. I know I'm a good scientist. I publish international papers and from here I'm going to Florida to speak at one of the biggest materials conferences in the world. Nanogirl is just a hobby I do because I feel it's important to create a science-literate society.
3. How would you describe your childhood?
I grew up working-class with two parents who married at 18 with no qualifications and no money. Mum worked in bars and Dad was in the Royal Air Force learning a trade. We travelled a lot. I learned how to be plopped into a place and adjust quickly. Mum's Hong Kong Chinese, so there's the "Tiger Mom" syndrome. She wanted me to be a doctor. Dad was just like, "be happy, do what you love, we'll work it out". The one thing I did have when I was very young was a computer, a huge expense for us. Of course I pulled it to pieces and taught myself to code. Dad was learning to be an electrical engineer so our dining room table was covered in circuits. At 8, he gave me my own soldering iron.
4. You give 20 per cent of your income to your chosen charities. Why?
I'm not very materialistic. The only jewellery I have is this ring I made on a 3D printer. I need enough to pay my bills and then the rest I want to be able to give back. I see a big inequality in New Zealand and I notice a very small amount of money can make a huge difference to those at the low end. I co-founded a charity called OMGTech where I teach kids, especially from low-decile schools, how to code and then write their own app. One of the kids came up to me and said, "I thought only rich people could make computer games but now I realise I can do it too". Suddenly you've opened up a spectrum of careers to a bunch of kids who are super-smart but missing out just because they're growing up in a situation that's out of their control.
