In be able to welcome such consistently high student numbers. 2014 our university, the oldest university of technology in Indeed, so great is the influx of students that we have to pull the Netherlands, will be celebrating its 172nd birthday. It out all the stops in order to be able to accommodate them all. Imay be old in years, but it has always been very much up This is an important sign that engineers are now highly sought to date in terms of its activities. Security, for example, is very after by the labour market even more than ever. It is still the much a contemporary theme, as witnessed by its extensive case that the vast majority of our graduates find employment coverage in the media. We are living in an increasingly complex more or less immediately. society, where new technology and old values clash and As high as the number of campus students may be, they form where our welfare is causing greater problems than is poverty but a drop in the ocean compared to the numbers of people elsewhere. In a society of this kind, issues relating to security we reach through online education. This is an experiment are becoming ever-more complex. The response to these that we believe in to the full. We are proud to be among the issues calls for a multidisciplinary approach to research. You can forerunners in the field of e-learning, a teaching method that we read more about this in the interview with Pieter van Gelder, are in the process of expanding step by step. Our own students professor of Safety Science and the Foundation Day Lecturer enjoy blended learning – a mix of face-to-face teaching and on the occasion of our 172nd anniversary, when he spoke online learning. In order to make outstanding education more exclusively on the topic of security. Multidisciplinarity brings accessible, we recently launched online Master’s courses. But rewards in other respects, too, as it is on the cutting edges our biggest success in 2013 was our Massive Online Open of different fields that outstanding new opportunities are to Courses on the renowned EdX platform: two courses on water be found.

TU Delft Education, after all, is our raison d’être, and it is pleasing to Highlights TU Delft 2013 - 7 - Pieter van Gelder Prevention is better than repression On 1 October 2013, Professor Pieter van Gelder was appointed as Professor of Safety Science at the Faculty of Technology, Policy and Management (TPM). Before that, since 1994, he was affiliated with the Faculty of Civil Engineering and Geosciences (CEG), where he conducted research on probabilistic methods in hydraulic engineering and construction. He would now like to apply that knowledge to other security domains. n 10 January 2000, Hydraulic Engineering at the time. flood defence. “We use optimisation Pieter van Gelder was The mathematical advisor from techniques for that, because the awarded the first TU Delft Rijkswaterstaat took some courses optimal dike height not only depends Odoctorate of the 21st first. “While I was still working for on the consequences of a breach, century. “One of the propositions in Rijkswaterstaat, I attended a number but also on the investment costs in a my PhD dissertation was that I might of lectures on civil engineering, sitting higher dike.
