Teaching - Courses on Optimization of Online Experiments /font>

Learning from Big Data. This is a hands-on undergraduate course on online experiments and website morphing. Bachelor students learn how to design, run, and analyze their own multi-armed bandit experiments using morphing-based algorithms.

Online Experimentation. This is a two-day course tailored to (1) seasoned professionals with a technical background that are increasingly taking over managerial responsibilities and handling internet project teams and (2) professionals who come from a non-tech background and want to have a better understanding of the ins and outs of optimal digital experimentation as they take over and manage such teams
