Companies & Consulting

Student vacancies/internships

Companies are invited to contact me for vacancies or internships for students in the master programme Business Analytics & Quantitative Marketing. Many students in this programme combine their master thesis with an internship. During their thesis work they tackle relevant data-related questions for various companies. Please send me a description of the context and research question of about one page. The best time for recruiting students for these positions is November to February.

Consulting

The Econometric Institute has set up a company to assist companies with data science related questions and companies: Erasmus Quantitative Intelligence (EQI). Faculty of the institute actively participate in the research projects of EQI.

Research collaboration

In many of my research projects I actively cooperate with companies. Companies with challenging research questions and a taste for academic research are invited to contact me to discuss the possibilities for cooperation.
