Madadh is also founder and member of the Executive committee of the International Windships Association; promoting the use of wind in commercial shipping".

Teaser talk
What is on offer now, in terms of economic empowerment and therefore self-determination, often comes at the cost of sacrificing indigenous cultures. I liken this to our loss of bio-diversity. In many cases we don’t appreciate what we’re losing until it’s too late. To empower indigenous cultures you need to go to where they are; physically, mentally and spiritually.

TEDxEde_Irene_van_Staveren_©ERIC BRINKHORST

Bio Irene van Staveren
Irene van Staveren is Professor of Pluralist Development Economics at the International Institute of Social Studies of Erasmus University Rotterdam. Her research and teaching present a wide variety of economic perspectives on key problems, such as gender relations, financial instability and economic inequality.

Talk teaser
I will explain why women's financial behaviour is less likely to lead to severe crises than men's. If Lehman Brothers were Lehman Sisters, the damage of the 2008 financial crisis would have been less due to three key gender differences in financial behaviour. The lesson is to stop rewarding stereotype masculine behaviour in three key areas in banks.

On the way I have been an educator, photographer, volunteer in humanitarian operations and a journalist.

Animals have the power transform us, they touch our hearts, they light passion in us, passion that can move us to action, it has the power to make us better human beings.

Talk teaser

Picture two men in a tiny boat on the vast Atlantic Ocean. They have nothing but some food, medicines and a satellite phone. Apart from the constant rolling waves and clouds sailing by overhead, there is nothing to be seen for miles around. Finally, the storm dissipates and calmness returns to the sea and the boat. On the dawn of their fifteenth day at sea, the sailors see the most beautiful sight they could ever wish for, the contours of a twenty meter yacht sailing towards them. The Talk is about the transformation process you are going through during an adventure at sea.

Koen Lekkerkerker

Pushing the boundaries of self-driving vehicles


Bio Speaker
Koen Lekkerkerker is a passionate engineer with various experience in artificial intelligence, control, and robotics. He is the chief engineer of the WEpods self-driving public transport project; a unique project in which small autonomous buses are driving public roads to explore the technological and regulatory challenges involved in self-driving.

Talk Teaser 
Everyone seems to talk about self-driving vehicles these days. But not many people can say that they are actually doing it. Those who do, like Tesla, are closely followed by media to cover any kind of failure. One thing is certain, making cars self-driving will both require and cause huge transformations in the world as we know it. How are we going to deal with these changes? What discussions, laws, and technological breakthroughs will be needed to let this transformation happen smoothly? Let’s see if we can find out during my TEDx Talk!

Wolter Pieters

Security politics: Un-thinging the Internet-of-Things

Bio Speaker
Wolter Pieters is an assistant professor in cyber risk at Delft University of Technology, Faculty of Technology, Policy and Management, and one of the initiators of the TREsPASS project. He studied computer science and philosophy of science, technology and society at the University of Twente, and wrote his interdisciplinary PhD "La volonté machinale: understanding the electronic voting controversy" at the Radboud University Nijmegen. Pieters’s research focuses on cyber security risk management in complex systems. He works with qualitative and quantitative socio-technical security models, attack models, and attack graphs, to discover and prioritise weaknesses, and evaluate countermeasures. In relation to such decision support, he is also interested in the ethics of cyber security and in the integration of security and safety. He published on electronic voting, verification of security properties, cyber risk management, and philosophy and ethics of information security.

Talk Teaser
With our washing machines and thermostats connected to the Internet, should we be worried about hackers? I will show that the underlying issue is broader: providing others access to our “things”, thereby turning them into services that reduce our own control. Security policies decide who is a threat and who isn’t.

Abigail Martina

"The best way to deliver this message is through music"





Born in 1989 and in love with music ever since her parents kept playing music of great artists like The Winans, Whitney Houston, Kirk Franklin and a lot of classic soul music. She played the piano since she was 10 years old. Funny enough she didn't think she could sing until she was 15 years old. But from that moment on she didn't stop. She started to develop her skills in singing and began to take classes. She pushed herself to sing and play the piano at the same time... and that payed off. Now she is a performing artist and this year she will graduate at the conservatory in Haarlem. Although Abigail knows how to play the piano and sings all the right notes, there is something more important than that, and that is that she wants to touch people with her music and show everyone there still is love and hope. The best way to deliver this message is through music.
