 Hi, my name is Jay, I'm from Maristem and Maristem resources are made by lots of different volunteers, who are all experts in their area and you're about to launch into some chemistry videos by Catherine and I thought it would be good to get to know her. So, hi Catherine. Hello. Thanks for sharing your resources with us. Can you tell us a little bit about yourself? Who are you? So, I'm currently a teacher at Maurici College in Canberra. I teach chemistry there, but when I'm not teaching, I like running and drawing and reading and I play the violin. But, you know, primarily I find science really invigorating and teaching science particularly so. So, that's why I do what I do. Yeah, cool. So, what do you do? I guess, what do you do? What's a day job kind of thing? So, the classes that I at Maurici, I teach years seven to 12, sometimes I say sometimes junior science and sometimes year 11 and 12 chemistry. I also teach as part of the ANU Extension program, which is a program for advanced year 11 and 12 students in the ACT, where they can come to the university and do first year university work in parallel with their schoolwork. Yeah, right. Cool. Well, that is great for us. You know what you're talking about definitely. So, can you tell us how you chose chemistry? What got you into that in the first place? So, I was chosen as one of the team members of the Australian Chemistry Olympiad team when I was in year 11. Before that, I really wasn't sure at all what I wanted to do. That kind of came as a bit of a surprise, that little path. But that put me on the path to science. I ended up doing a PhD in chemistry and at the same time as the PhD, I also completed a diploma of education because I knew that I really liked teaching. So, I finished my PhD. I did three years of research at the University of Edinburgh, which I really loved. I was in the Department of Physics. I was doing kind of like a crossover physics chemistry area, material science actually, really. But at the end of the postdoc, I found all the way through it, I had still been thinking about teaching. So, I thought, well, give teaching a go. And launched into it, terrified that I would finish my first year and wish that I could get back into research. But actually, I finished the first year and absolutely loved it and I've been doing it ever since. Yeah, wow. Awesome. All right. Well, thank you. You're all going to learn a lot more from Catherine right now. So, I'll leave you to it.
