21yearold Julia Ruscher is a math genius. Numbers have been her passion from an early age. Now she is studying at the Berlin Mathematical School, where she is involved in research projects in Israel and the US.

Julia Ruscher's area of expertise is stochastic processes, which seek to make sense of seemingly random occurrences. Her research focuses on the growth of animal and human populations. We spend a day with Julia Ruscher at university in Berlin and take a look behind the scenes at math research at the highest level.
