Plus is based at the Maths Faculty at the University of Cambridge so we have lots of opportunities to talk to interesting mathematicians about their work and their working lives. This week we speak to Holly Krieger, who is a professor here in a podcast that we originally produced for the Maths Faculty.

Holly works in the overlap of two areas of mathematics: number theory – which is famous for problems such as Fermat’s Last Theorem – and complex dynamics, which gives rise to beautiful fractals. This intersection is known as arithmetic dynamicsand it’s an exciting, relatively young area of research. Holly’s work has been very successful, being awarded several prestigious prizes. And she is also known for her appearances on the Numberphile channel where she has shared the beauty of maths in a range of areas, from centrifuge to the Mandelbrot set.

Holly told us about how she came to her current research, the benefits of a career in maths, advice for younger mathematicians, and her appearances on Numberphile.
