## "I’m using data to support business decisions"

I’m currently working on a graduation project where I use data science and geo-experiments to test the effectiveness of online marketing. What would be the effect of continuing a certain marketing campaign in one region and stopping it in another? The logic puzzle aspect of data science is very enjoyable to me, especially in the overlap between technology and business.

Because of the bachelor’s degree program I did, I did a pre-master program to get my programming, statistics and math up to par. The JADS Campus in Den Bosch is great and very small. After I graduate, I’d like to set up a business with a partner. I like starting and expanding things. I’m still looking for a concrete idea.
