I currently work at Google in Search/Ranking. Before that I worked at Max-Planck doing machine learning in Robotics. I also worked on an ML project with Converge, and spend some time teaching algorithms in my university before starting my PhD.

Work at Google

I work in Search Quality. My work at Google is very interesting, including a lot of machine learning work, data analysis and working with a lot more data that could fit in a single machine. You can learn more how the ranking algorithm works in this official Google post.
