How I Use Maths In My Job:
For my work, we often need different kinds of probabilities related to words. For example, what is the probability that a word “bicycle” appears in a text about outdoor sports? And what is the probability for the same word in a text about musical instruments?
Also, more languages can be involved: what is the probability that the English word “bicycle” corresponds to the French word “bicyclette”?
The probabilities are sometimes calculated as fractions, but recently they are usually calculated using socalled “neural networks”. These networks are nothing else than complex mathematical functions.

My Work:
I use maths to process human languages (it is called Natural Language Processing /more maths/, or Computational Linguistics /more language/)

I work in Natural Language Processing (NLP), a science which teaches computers to process and analyse natural language (English, German, French, Japanese, Chinese, …) data.
Most of the time I work on machine translation, a subfield of NLP where computers translate from one language to another using probabilities. The probabilities are calculated using neural networks. These networks are essentially nothing else than complex mathematical functions.
Do you know what Google Translate is? Just one of many computer programs for machine translation.
I also teach students at the university about all those things.
And, before I started to work using maths on languages, I worked on using it for sounds (particularly speech).

My Typical Day:
every day is a little bit different, (especially when travelling), except the start with a cup of coffee

What I'd do with the prize money:
I am not sure what I can do exactly, but I will ask my university how it can be used to explain school kids how maths is used for languages

Tell us a joke.
All functions in Functiontown became scared to death when a dangerous stranger known as Derivative arrives to Functiontown and starts to change every function on their way. Therefore, all functions run to their homes to hide, except one which is happily walking on the streets, totally relaxed, singing. Others become worried: "Hey, you, haven't you heard about Derivative?! Better go somewhere to hide, it's dangerous out there!", and he replies "No worries, folks, I'm exponential!"
