David | Senior Space System Engineer

After graduating from his Aerospace Engineering bachelor, David continued his master’s in Aerospace Engineering in the Spaceflight track, specialising in Space Engineering. In 2021, he finished his studies and started working as a Space System Engineer for Ubotica Technologies, a company specalised in artificial intelligence technologies on board of satellites. Why did you decide to study Aerospace Engineering? “Actually, I was not too sure about what I wanted to study after high school. I figured I would try something challenging, but interesting, and that is how I ended up at the bachelor Aerospace Engineering. I continued my studies in the Spaceflight track for my master, and my interest for that actually came from my minor during the third year of the bachelor. I did my minor in International Entrepreneurship and Development, and for that I went to Suriname for a few months. During that time, there was a rocket launch in the neighbouring country French Guiana, and we got the chance to go there. Our project had nothing to do with that, but that was such an incredible experience. Space has always fascinated me, but if I have to name one moment that piqued my interest in space, it is for sure that visit to the space centre in Kourou.” How did you experience being a student? “My student time was amazing. I learned a lot, had a lot of fun, but I also really got the chance to develop myself in multiple ways. The Aerospace Engineering bachelor at TU Delft is one of the best studies in this field in the world, so you truly get a solid foundation to become an engineer at the top technical companies in the world. But even outside of the technical knowledge you acquire during your studies, you learn a lot from extracurricular activities as a student. For example, I did a board year with De Brielse Zeilschool, a sailing school, and I learned a lot from that experience as well. It had nothing to do with my studies, but I learned many other valuable skills while managing a sailing school. This can be quite challenging, as you need to work closely with people in intense situations, guide them, and solve problems together. So, next to the hard skills I learned throughout the bachelor, I also learned about valuable soft skills through these sorts of extracurricular activities.” How did you go from being a student to working for Ubotica Technologies? “For me that was quite straightforward. My journey to being a Space System Engineer started during my master internship. This is a mandatory part of the education program, and I went to Dublin for half a year to work on a space project on applications of data from satellites at Intel Movidius. That was already a leap into the unknown, because I had not really worked with data like that yet. I thought it was interesting, and I ended up learning a lot from that project. The project itself also turned out to be incredibly successful and we ended up writing three scientific publications on it. Some of my colleagues at Intel Movidius later joined a new company, called Ubotica Technologies. After finishing my thesis, they got back in touch with me and asked me to join the company. I did not have to think long about it - getting the opportunity to work on real space missions in a small and talented team, what's not to love?” Did you already know you wanted to continue in an aerospace related company? “During my master, I indeed realised I wanted to stay within the space industry. After my internship, I performed my thesis research with ESA in the Automation and Robotics section. After that, it felt like a logical continuation for me to stay in the space engineering field. What I really like is that I truly make an impact with the work I do now. As a student you do that through your projects too, but now I can really see how my work contributes to society. I like that a lot, and the transition from being a student to working was very smooth. TU Delft prepares you well for the work life after your studies. You have to do an internship, which is incredibly valuable. You get to experience what it is like to work at a company and tackle projects with colleagues. So, that prepares you very well for your career after your studies.” How else has the Aerospace Engineering programme prepared you for your career? “The Aerospace Engineering programme has prepared me well in many ways. First of all, of course, the courses and high quality of the education with very relevant projects prepare you very well. During my master's in Space Engineering, I had a lot of project-based courses. The content and set-up of those were very applicable to my daily work now. I learned a lot from those projects, both from the bachelor’s and master’s programme. During your bachelor thesis for example, you have to solve a difficult technical problem with your group, applying system engineering as well, and in my case, this was also a space-related project. I still look back to the system engineering approach we used during that project, and I can actually apply some of that to my work now. During your studies, you learn how to do academic research well. The master's thesis is such an elaborate project, it truly gives you a very solid scientific foundation. I notice that I apply those skills almost weekly. At my company, we also regularly publish papers or speak at conferences, and even our interns can do this already because they have such a solid foundation from their studies already. Next to the courses, the network that you build is also incredibly valuable. You get to know a lot of people who will later start working in the same field as you. From that, I got a very solid network which is very valuable to me, both personally and professionally.” Finally, do you have any advice for future Aerospace Engineering students? “If I would have to give a piece of advice, I would say that the study is important, the courses are very important, and you will need to work hard and do your best. But, you also need to remember that it is equally important to do things next to your studies. Things like voluntary work, committees, a board year, a minor abroad, internships. These things really help you develop yourself for your life after your studies. Besides that, these extracurricular activities are extremely fun and you grow so much as a person from that. So, even if it is not directly applicable to the studies, you still learn a lot from it. And lastly, at this university, you really do make friends for life. There is a tight community, and you can find the right community for you in many different ways. There are sport associations, theatre associations, and so much more. You can do a lot of fun things in Delft. You can build strong friendships both within the academic setting and through extracurricular activities. I think that is one of the strengths of this university.”

Three Students Nominated for the ECHO award

Three TU Delft students have been nominated for the ECHO Award 2024. The ECHO award is awarded to students with a non-western background who are actively engaged in society. Sibel, TJ and Pravesha talk about their background their nomination. The finalists will be selected on September 27th. Sibel Gökbekir How has your background influenced your academic journey? As a woman with Turkish roots, my academic journey has been about more than just pursuing degrees in engineering and law; it’s been about consistently advocating for the diverse needs of women and multicultural groups, ensuring their voices are heard in important decisions. This is why I actively contributed to different board positions at TU Delft, working to promote inclusivity and equality. My background inspired me to explore how engineering, law, and social justice intersect, particularly in empowering marginalised communities. I chose to study energy transitions and human rights to contribute to a fairer, more inclusive World. How have you turned this into contributions to society? I’ve dedicated my academic and personal life to promoting diversity and inclusion. As a youth ambassador for Stop Street Harassment, I aimed to create safer spaces for women and minorities because I believe everyone has the right to feel free and safe in society. Through the Turkish Golden Tulip Foundation, I advocated for vulnerable communities in earthquake relief. Additionally, I founded an initiative for migrant students in Rotterdam-South and I have been committed to improving educational opportunities for secondary school students with a migration background. Next, I gave guest lectures across the Netherlands to educate the younger generation about climate change and equitable energy transitions, emphasising the importance of a fair transition for all communities. What does it mean for you to nominated to the ECHO award? I feel very honoured to have been nominated on behalf of TU Delft. My commitment to community engagement is part of who I am, and therefore the ECHO Award is more than just a recognition; It offers me an opportunity to further expand my contributions to a more inclusive society. As an ECHO Ambassador, I plan to expand my efforts in promoting equality and sustainability, while inspiring others to take action for a more equitable World. TJ Rivera How has your background influenced your academic journey? My background as a Filipino in a Dutch-speaking bachelor’s programme made my academic journey both challenging and enriching. Being gay in a male-dominated field like Architecture, where most role models were heteronormative men, added another layer of difficulty. It was intimidating to not see people like me represented. However, this experience fuelled my belief that systems can and should be challenged, changed, and updated. I aimed to bring a fresh perspective, advocating for greater diversity and inclusivity in the field. How have you turned this into contributions to society? I translated my personal challenges into tangible contributions by advocating for inclusivity within architecture. Together with like-minded individuals, I began exploring the intersection of identity, sexuality, and architecture, and collaborated with my faculty’s diversity team to raise awareness. As I became known for my work with the queer community, I saw an opportunity to create lasting change. I co-revived ARGUS, the once-inactive study association for the Master of Architecture, which now serves as a platform to discuss and address issues of diversity within the field. This initiative continues to foster a more inclusive academic environment. What does it mean for you to be nominated to the Echo award? Being nominated for the ECHO Award is a significant milestone in my journey to expand my mission beyond the confines of my faculty. This national platform provides the opportunity to raise awareness and advocate for social justice on a larger scale. I believe students are key to driving change, and my focus is on amplifying the voices of the queer community, which is often overlooked. The ECHO Award will enable me to form partnerships with organizations and universities, further promoting diversity, inclusivity, and equality. It’s a chance to create broader, tangible change, addressing the needs of those who often go unheard. Pravesha Ramsundersingh How has your background influenced your academic journey? As a woman in STEM (Science, Technology, Engineering, and Mathematics), my background has been a powerful motivator to challenge gender disparities within Computer Science. Experiencing firsthand the underrepresentation of women in this field, I have been driven to not only excel academically but also become an advocate for diversity. Through leadership roles in the Faculty and Central Student Councils, I’ve focused on creating an inclusive environment that supports women and minority students, ensuring that everyone has the opportunity to succeed. How have you turned this into contributions to society? I’ve translated my experiences into actionable contributions by actively advocating for DEI at TU Delft. I ensured sexual education and consent training for 3,000 freshmen students, and I led initiatives like the Social Safety Initiatives Conference alongside the Dutch National Coordinator against Racism and Discrimination. In my student governance roles, I pushed for policies that address gender discrimination and social safety concerns, creating a more supportive environment for students of all backgrounds to thrive in both academic and social spaces. What does it mean for you to nominated to the ECHO award? Being nominated for the ECHO Award is an incredible honour that highlights the importance of the work I have done to promote DEI.

NWO grants funding for innovative research on physical experimental environments

How to move from experiment to mainstream? A consortium led by professor Tamara Metze, has been awarded a prestigious grant from the Netherlands Organisation for Scientific Research (NWO). In search for pathways toward more sustainable futures, Metze and her team will explore how various innovations in field labs such as The Green Village, in urban living labs such as Engy Lab South-East in Amsterdam, and in all sorts of citizens’ initiatives, can be mainstreamed and make more impact on sustainability transitions. Pilot paradox The project ‘From EXperiment to sustainable change: TRAnsformative methodologies for Innovation and learning’ (EXTRA) seeks to overcome a persistent “pilot paradox”. In this paradox, much experimentation takes place but long-term systemic impact remains difficult. Researchers together with all sorts of change makers will synthesise existing knowledge on how to mainstream, upscale, spread, broaden and deepen developed innovations. Tamara Metze: ‘I am excited to unravel what are effective ways of cocreation that lead to mainstreaming the positive changes made in experimental environments. We will figure out how learning and innovation can lead to lasting changes in regulations, policies, and financial systems and the biophysical environment.’ Tamara Metze Read the NWO press release Actionable tools The project is crucial for accelerating sustainability transitions. By refining methodologies for mission-driven experimentation and develop hands on tools for all sorts of change-makers, it will be easier to mainstream the sustainable lessons and innovations. ‘These tools will not only aid grassroots innovators but also influence institutional and organisational structures, ensuring that lessons learned from experiments are better anchored in policies, regulations, and organisations’, explains Metze. The project will employ a transdisciplinary action research approach, bringing together knowledge from various disciplines and policy domains. By co-creating solutions with public and private partners, the research will have an immediate impact. In the long term, the project aims to build a more efficient innovation ecosystem, contributing to more impactful and sustainable outcomes for both society and the environment. Projectpartners TU Delft, VU Amsterdam, Wageningen University & Research, Hogeschool van Amsterdam, Erasmus Universiteit Rotterdam, Hogeschool Rotterdam, The Green Village, AMS Institute; PBL Planbureau voor de Leefomgeving, WoonFriesland, Dijkstra Draisma, Provincie Noord-Holland, Ministerie van Binnenlandse Zaken, PRICE / Almere, BouwLab, Alliantie Samen Nieuw-West, Innovation Quarter.

Unusual waves grow way beyond known limits

Waves that come from multiple directions are extremer than extreme. These remarkable deep-sea waves can be four times steeper than what was previously imagined, as is shown in research by TU Delft and other universities that was published in Nature today. A long time ago, stories were told of mysterious rogue waves that materialised out of nowhere and could topple even the largest ships. These waves lost their mythical character when the first rogue wave was recorded at the Draupner platform in the North Sea. In 2018, Ton van den Bremer and his colleagues at the Universities of Edinburgh and Oxford managed to recreate the Draupner wave in the lab for the first time ever, and this opportunity to study freak waves closely produced unexpected insights. Multiple waves push up water New research by the research consortium now shows that these remarkable waves do not break when traditional theories hold they should, the secret behind which lies in how they arise. Ton van den Bremer, expert on fluid mechanics at TU Delft and led the study, explains: “When most people think of waves, they think of the rolling waves you’d find on a beach. The type of wave we studied occurs in open water and arises when waves coming from multiple directions come together. When these waves with a high directional spread converge, the water is pushed upwards, forming a partially standing wave. An example of this is known as a crossing wave. How crossing waves arise Under certain conditions at sea, waves from multiple directions occur. This can happen in a place where two seas meet, or where winds suddenly change direction, as in a hurricane. When waves from two directions meet, a cross wave occurs, provided their directions are far enough apart. The study also shows that the further apart the directions are, the higher the resulting cross-wave. Travelling waves break when they reach a certain limit, this is when they reach their maximum steepness. The study shows that waves with a multidirectional spreading can get as much as 80% steeper than this limit before they start breaking, which means they can get almost twice as high as ‘normal waves’ before they start to break. Travelling wave (l) and a wave with high directional spreading (r) Breaking waves that grow Next, the researchers found another highly unusual phenomenon that defies existing theories, a phenomenon that is unprecedented according to Van den Bremer: “Once a conventional wave breaks, it forms a white cap, and there is no way back. But when a wave with a high directional spreading breaks, it can keep growing.” The study shows that these enormous waves can grow to twice their original steepness while breaking, which is already twice bigger than the conventional limit. Together, the waves can grow four times steeper than previously thought possible. Damage to offshore structures The knowledge that multidirectional waves can become as much as four times larger than was deemed possible can help design safer marine structures. "The three-dimensionality of waves is often overlooked in the design of offshore wind turbines and other structures in general; our findings suggest this leads to designs that are less reliable", says Mark McAllister of the University of Oxford, who led the experiments and is now a senior scientist at Wood Thilsted. Innovative vertical sensors made it possible to take accurate 3D measurements of waves. Innovative 3D measurement method A 3D measurement method developed in the FloWave lab paved the way for these new insights. “Conventional 2D wave measurement methods weren’t up to the task”, Van den Bremer explains, which is why the research group designed a new way to create 3D wave measurements. Ross Calvert of the University of Edinburgh: “This is the first time we've been able to measure wave heights at such high spatial resolution over such a big area, giving us a much more detailed understanding of complex wave breaking behaviour." FloWave Ocean Energy Research Facility in Edinburgh. The circular basin has a diameter of 25 metres and can be used to generate waves from multiple directions. Header image by: Fabien Duboc
