Jelle Millenaar is the Lead of Identity at the IOTA Foundation, a Berlin based non-profit organization focused on the development of a green and feeless Distributed Ledger Technology. With a background in Game Programming and Medical Biology, he started working as a Blockchain consultant in 2017. He is a specialist in Self-Sovereign Identity, enabling people, organizations and devices to exchange verifiable personal information, while maintaining privacy and control over their own data.

Bitcoin has a significant negative effect on the world's carbon emissions, surpassing entire nations carbon emissions to keep the network secure. After years of innovation, blockchain technologies have gotten significantly more green. Even better, some projects actively contribute to a greener society by incentivizing a lower carbon footprint. This talk will explain why Bitcoin creates such big emissions, how newer generations of the technology have gone beyond the need for emissions and how projects like IOTA even have a positive impact on the environment.
Ardjan Zwartjes & Jorrit Hagen
Ardjan Zwartjes & Jorrit Hagen | Nedap
Ardjan Zwartjes is an experienced data scientist who recently started working for Nedap Livestock Management (LM). He obtained his MSc and PhD in Computer Science at the University of Twente and has experience with wireless sensor networks, distributed computing, time series forecasting and pattern detection.
Jorrit Hagen obtained his MSc and PhD degree in Astronomy at the Rijksuniversiteit Groningen. As an astronomer he analysed large data sets based on observations from both ground-based and space telescopes. Since January 2020 he is working at Nedap Livestock Management as a data scientist to improve upon the current heat detection algorithm.

Ardjan and Jorrit will show how Nedap Livestock Management (LM) links IT and Environment. A smart interplay between sensor technologies, big data, IT infrastructure, machine learning models and software enables Nedap LM to make dairy farming more efficient. Their sustainable solutions not only reduce the carbon footprint but also increase animal welfare.

Vincent Nibbelke | Datacadabra
Vincent Nibbelke is lead computer vision engineer by Datacadabra. Despite his tremendous knowledge and experience into computer vision and data science, he loves to bring things back to the core. In a very down to earth manner he can explain the most high tech innovations. Vincent started his journey at the University of Twente, studying Electrical Engineering and Human Media Interaction. Thereafter, he begun his career in computer vision at SciSports, before switching to Datacadabra. Vincent’s brain provides the company clients with the most creative AI solutions to solve their challenges, while he always keeps the practical implications in mind.

Datacadabra, a digital intelligence agency located at the University of Twente campus, will take you to the world of artificial intelligence. They develop smart solutions based on artificial intelligence that sense, interpret, and assist. Through their solutions people are enabled to work efficiently, while embracing the future ambitions for sustainability, safety, biodiversity, and circularity in their daily work.

Based on the MowHawk, a smart camera system for nature inclusive verge management, AI detection models will be explained. Datacadabra believes AI will play an important role in the future transitions that our society needs to make for securing a healthy world.
Diederik Bakker & Nando Tolboom
Diederik Bakker & Nando Tolboom | Realised
We are facing the biggest challenge of the century: climate change and the energy transition. With energy prices going through the roof and the combination of geopolitics and energy becoming very apparent, we are starting to realise that accelerating the energy transition does not only benefit our planet. In this talk, Nando Tolboom, PhD candidate at the Energy, Materials and Systems research group, and Diederik Bakker, graduating MSc student Cyber Security, dive into the subject of the energy transition. We are using many different sources of energy in our daily lives, and it is not necessarily intuitive to compare them. We will introduce you to the peanut butter perspective, which can be of big help in reasoning about energy. Before looking at the Netherlands as a whole, we look at you and your direct environment - our university. Finally, we will discuss the role of IT in the energy transition on several levels. While these examples could inspire your future career, you can already start applying IT to the energy consumption in your student house - we will gladly show you how!

Realised, a start-up founded by two CS students in 2018, believes that transparency and visibility can help organisations to pilot through the transition from policy to measures regarding sustainability. Leaning on software for visualising energy usage and bookkeeping carbon emissions, we advise organisations on their pathway to become carbon neutral. Click here for more info on Realised.

Melanie Königis a PhD student in computational biophysics at the University of Groningen and part of the BaSyC ("Building a Synthetic Cell") consortium. She is using computer simulations to model the complex interplay between millions of molecular building blocks present in all living beings to understand the most fundamental processes of life like the division of cells.

Creating artificial life from individual lifeless components might sound like an idea straight out of a sci-fi novel but is actually one of the grand scientific and intellectual challenges of the 21st century. Within BaSyC the aim is to put together the basic molecular components to build a synthetic cell from the bottom-up. They want to understand how all the different molecules collectively operate to form a living cell that sustains itself, grows and divides. Answering the fundamental question How does life work? will bring huge intellectual, scientific, and technological rewards.

Wouter Klein Wolterink obtained his MSc. and PhD Computer Science at the University of Twente and now works at engineering and consultancy firm Witteveen+Bos. Witteveen+Bos is a collective of more than 1400 engineers who possess an intrinsic drive to resolve complex issues and help society to progress. The energy transition, climate adaptation, flooding problems, healthy cities, circular economy and large-scale replacement of infrastructure are only some of the major challenges that Witteveen+Bos can help with. Because of the scale and complexity of these challenges, having a strong IT component more and more becomes a necessity to reach the desired goals. Wouter helps this digital transformation of the engineering process and looks for ways where IT can help engineers to bring their solutions to the next level.

We are facing many societal and environmental challenges: the energy transition, climate adaptation, biodiversity collapse, circular economy, and large-scale replacement of infrastructure, to name just a few. These are large, complex, and multidisciplinary problems that involve many stakeholders whose interests often clash. Effectively applying IT allows you to take an integrated and iterative approach and is therefore a requirement to solve these problems. In this talk we will look at some of the societal and environmental challenges that we are facing today, how IT can help to tackle these challenges, and what your role as an IT professional can be in this.
