Dirk Gerrits possesses expertise in latex, algorithms, programming, computer science, simulations and 13 more skills. He is proficient in German and English. Colleagues describe him as "Dirk is a walking algorithm encyclopedia. We worked together on a number of projects that involved machine throughput optimization software. Dirk has impressed me with his knowledge of a wide range of algorithms. Applying his theoretical knowledge and research skills he designed and prototyped combinatorial optimization algorithms that perform well in our complicated domain. Furthermore he proved multiple times that he can explain his ideas in a simple-to-understand manner, tailored to the audience: in presentations, over coffee at the whiteboard, and in well-written documentation."
