Moreover, it should in 2003 to create a new department in the Max Planck not stop making clear to the larger public what the role Institute in Potsdam, but I still feel very connected to of science in our society is. First, science provides deep Austria and in particular. I also feel that this is insights into our world and for our future. An institute a project that Austria needed, an institute focused on such as IST Austria must do everything to foster public great people and excellent, fundamental science, excitement for scientific discovery, so that people are without being guided by politics. While there are other proud of science, not afraid of it. But, in addition to this, smaller and larger research institutes in Austria doing scientific research trains scientific minds. This is not said great work, the difference is that IST Austria is also a often enough: the graduates of IST Austria, whether or graduate university. not they stay in science, have scientific training and thus a particular way of looking at problems, different from Since its opening in 2009, the Institute has developed someone with a commercial background, for example. at a remarkable pace. What do you see as the most Such people are very valuable and very important for significant challenges IST Austria will face in the our technology-based societies. coming years? In addition, IST Austria can do a great deal to attract Scientifically, I think this is a very interesting time for the excellent people, projects, and ideas to Austria, both Institute. IST Austria has grown very rapidly, and until by increasing the quality of the research landscape, now, the leadership was looking for the best scientists and by working together with the traditional universities that could be hired, in a wide variety of fields.

22 23 Taking Their Next Steps

IST Austria Alumni

Growing numbers of alumni are leaving IST Austria to make their mark on the world, and the development of their careers offers important feedback to IST Austria as an educational institution. IST Austria alumni have joined universities, research institutes, and companies around the world. Around two thirds have continued in academia, many of them in top international institutions such as Harvard University, Stanford University, Johannes Inma Philipp MIT, ETH Zurich, and the Max Planck Institutes. In addition, computer Reiter Sanchez Romero Schönenberger scientist Thomas Wies, now at NYU, became the first IST Austria alumnus to receive tenure.

38 39 encouraging collaborations across scientific fields Communicating Science

Over the course of 2017, IST Austria organized and hosted numerous scientific events, encompassing a wide variety of formats and disciplines. Ranging from colloquium lectures given by renowned scientists to special-topics conferences, these events brought science enthusiasts— members of the general public as well as top researchers—to campus to exchange ideas and discuss the latest scientific trends and discoveries. Four of the many events held on campus are highlighted here; a list of major talks and conferences can be found in the “Facts & Figures” section.

42 43 Outreach and Science Education

A key role of research institutions is to share the wonder, excitement, and methods of scientific research, as well as the discoveries that result, with their local and global communities. With this in mind, IST Austria reaches out to the general public, especially to elementary and high-school students, through numerous community and science educa- tion events organized on campus, as well as by participating in many regional scientific events.

Science education in particular is a key mission of the Institute: it is essential to expose students to scientific discoveries and thinking, and build enthusiasm for science from early on, and to continue to foster curiosity and deeper learning as children grow. Scientists and scientific institutes can contribute expertise and facilities, adding Open Campus Summer Camp for Children’s University How do plants breadth and depth to classroom and extracurricular Science Youngsters of Vienna dance? activities.

54 55 Growth and Future Perspectives

Over ten years of growth, IST Austria has passed many milestones—in research, in recruitment, in construction, and in grants and fundraising—and 2017 continued the rapid pace of development. Despite, or because of, what it has already achieved, the Institute begins the next ten years still holding big visions for the future, and still guided by the same principles on which it was founded.

2006 2009 2010 2011 2012 2013 2014 2015 2016 2017 2026 IST Austria founded campus opens first graduate students over 190 employees Lab Building East over 350 over 30 research first PhD degree more than EUR 100 600 employees, over 90 research by law with 37 employees, join the Institute, completed employees groups on campus awarded, million in third-party 31 ERC awardees groups expected including 4 professors Bertalanffy Foundation Lab and Office funding acquired among the 49 building completed Building West opens professors under contract

Expanding the research landscape Campus community Since the beginning, IST Austria has focused on hiring The new buildings and new research facilities reflect the great minds, putting the emphasis on quality, rather than rapid and significant growth in the campus community: research focus. This has resulted in an outstanding in October 2017, the Institute passed 600 employees, group of scientists at all career levels. Of the 49 faculty comprising approximately 400 scientists, 100 scientific members currently under contract at IST Austria, support staff, and 100 administrative staff, together of 14 professors conduct research in the formal sciences some 60 nationalities. IST Austria will continue to grow (computer science and mathematics), 26 in the life through the next phase, eventually reaching more than sciences (biology and neuroscience), and 9 in the 1’000 employees, and 90 to 100 research groups by physical sciences (physics and chemistry). At the end of 2026. the next phase, 2026, these three research clusters are expected to be roughly equally represented on campus. To support the growing community, 90 additional apart- ments for scientists have been built on campus; these Construction will be handed over to the Institute in April of 2018. In As additional buildings are designed and erected, the addition, the kindergarten was expanded: children as Institute seeks to strike a balance between two goals: young as three months can join one of three groups, and first, to foster interdisciplinarity by mixing groups with an additional group is expected to be created in early different research focuses within buildings, and second, 2018. to allow the needs of the scientists to inform the shape and facilities of a building. This year, preparation started for the construction of the next scientific laboratory building, and planning has begun for a future Visitor Center as well as another laboratory building. The coming years will also see an expanded machine shop, a central storage unit, a multi-purpose experimental facility, and the opening of the new administration building.
