Spotlight on Young Researchers: Gil Georges

During his computer science studies, Konstantinos Papadopoulos realised how many unexplored areas there are in the field and his desire for becoming a researcher was born. Now in the 2nd year of his PhD at the SnT at the University of Luxembourg, the Greek national works on developing innovative new approaches to security surveillance.

Senior Postdoc Sebastian Scheer’s thirst for understanding how biological systems work led him to dive into the world of immunology research. After moving from Germany to Canada, the Luxembourg national got the chance to set up his group leader’s new lab in Australia, where his research revolves around the T cell, a key player in the shaping of immune responses.

Neurogenerative diseases and cancer affect millions of people worldwide, especially people over 60. While advances in diagnosis and treatment have been made, there are still many open questions on the path to better treatment and earlier diagnosis. Translational neuroscientist Pauline Mencke studies a gene that is involved both in Parkinson’s disease and the brain cancer Glioblastoma multiforme.

Ever since he was a child, Jo Hoeser wanted to understand the function of complex systems. He found himself taking apart and trying to fix broken electronic devices. Then fascination for chemistry came into the mix. Fast forward some years and the Luxembourg national completed his AFR PhD in biochemistry at the Albert-Ludwigs University Freiburg – and wants to return to the Grand Duchy to continue his career in research.

An estimated 55 million people in the world suffer from dementia, with the number estimated to increase to 78 million by 2030. In Luxembourg, more than 10,000 people suffer from dementia, including patients affected by Alzheimer’s disease and Dementia with Lewy Bodies. These incurable diseases have an increasing socio-economic impact along with the burden on patients and caregivers. One of the approaches researchers are taking is studying microglia, immune cells in the brain.

When the first satellite was launched in the 1950s, earth orbit was a lonely place. Since then, more than 11,000 satellites have been launched into space and over 3,000 are still in operation. Estimates suggest an exponential increase in satellites in the next years, creating a challenge for the effective allocation of the needed bandwidth and power. Researchers are developing algorithms to more effectively allocate the resources where and when they are needed.

Carbs are all around us: a major constituent in food, they also play a role in many biological processes such as intercellular communication; they are in demand in the pharmaceutical industry, where they are currently used as anticoagulants and in skincare. With the goal of no longer having to rely solely on nature’s production of carbs, scientists have been working on ways to ramp up production. A case for chemistry!

Paul Johanns works in a research field one does not read about every day: knots. As part of his AFR PhD at the École polytechnique fédérale de Lausanne (EPFL), the Luxembourg national combines high-precision model experiments, computation and theory to untangle the influence of topology on the mechanics of complex knots, particularly those used in surgical procedures.

Nina Hentzen, an organic chemist working on the chemical synthesis of collagen, is fascinated by research at the interface of chemistry and biology. The Luxembourg national is in the second year of her AFR PhD at ETH Zürich – and has just been selected to attend the renowned 2017 Lindau Nobel Laureate Meeting.

For his AFR PhD at Trinity College Dublin, historian Michel Summer is re-assessing the political activity of medieval Anglo-Saxon missionary Willibrord, who in addition to being a landowner, scholar and ambassador, founded a monastery in Luxembourg. We spoke to the Luxembourg national about how history promotes critical thinking, and why he believes historians are needed more than ever.

Excessive use of fertilisers in agriculture has led to nitrogen pollution, and calls for bio substitutes are getting louder. PhD candidate Bella Tsachidou from Luxembourg Institute of Science and Technology (LIST) gathers scientific evidence on the benefits of biogas residues and their suitability as biofertilisers, while providing support for the modification of nitrogen-policies on European and global level.

Thomas Schaubroeck specialises in sustainability assessment of products. We speak to the Belgian national about the research he is undertaking in the framework of an Industrial Fellowship between the Luxembourg Institute of Science and Technology (LIST) and company Tarkett; how working with industry differs from academia; and how he hopes his research can help industry steer toward a more sustainable future.

A type of insect known as whitefly spreads plant viruses and has devastating effects on the vegetables that we depend on and thanks to climate change their negative impact on agriculture is set to increase in the future. Current methods to protect crops depend on delicate relationships between whiteflies and their natural enemies, our crops, and microbial communities, a delicate balance threatened by climate change. Researchers are working with a ‘climate in the lab’ to get a better understanding of what could happen, with the ultimate goal to generate solutions to protect food security.

Looking at popular culture, big tech and ongoing societal debates – technological progress in Artificial Intelligence (AI) affects us all. Researchers from numerous scientific fields are working on the best way to bring AI forward, including the study of systems able to autonomously reason over arguments – calculators for philosophical, ethical or legal debates.

Alex Gansen first dabbled in research during his Masters studies in physics at the University of Fribourg (Switzerland), and then decided he wanted to take on the challenge of a PhD, so the Luxembourg national returned to his home country. Alex has just submitted his thesis at the end of the 4th year of his AFR PhD in computational electromagnetics at the Luxembourg Institute of Science and Technology (LIST) in collaboration with the College of Engineering in Swansea. He sees the close links between local industry and research in Luxembourg as a great advantage for the future of research in the Grand Duchy.

Is it possible to use mathematical indicators to alert about natural disasters and help in the early detection of disease and health issues? Over the past 15 years, scientists have been working on bridging mathematical theory and empirical evidence to do just that. To move the science forward, a key challenge is the underlying mathematical problem, as well as determining how the indicators should be applied.

Vegetable oil – mainly palm oil – is heavily relied upon in the production of food, cosmetics, and biofuel. The increase in droughts also affects the standard cultivation of palm oil – alternatives are needed. Agricultural scientists are investigating the potential of a new alternative drought-resistant source for the most widely-used kind of vegetable oil.

When one thinks of banks and financial institutions, the word ‘research’ may not come to mind. However, research has much to offer these institutions, for example new tools to help with delivering critical services. As part of his PhD at the University of Luxembourg, Italian national Pier Mario Lupinu researches issues related to post-resolution in banking and finance.

Pit Ullmann’s interest in natural sciences was piqued in high school. The Luxembourg national went on to study molecular biology at the University of Innsbruck and then found himself desiring a job that would be both interdisciplinary and diversified – fast forward and Pit is now completing his AFR PhD at the University of Luxembourg, where his research group studies why and how colon cancer develops and spreads.

Can we predict the likelihood of a hazelnut tree becoming sick? Or what quality defects, and in what percentage, will be present in the final harvest? Science could soon make this possible, thanks to a hazelnut quality forecasting system based on a combination of machine learning and simulation models.

Stemming from Italy, Indonesia, Luxembourg, Portugal and Spain, the members of the Experimental & Molecular Immunology Group truly are an international team. In the group of FNR ATTRACT Fellow Prof Dr Dirk Brenner at the Luxembourg Institute of Health (LIH), the team of young researchers investigates different aspects of the immune system with one common goal: Understanding how our immune system is regulated by different mechanisms – and how this knowledge can be used to combat disease.

When we wrote about Miguel Olivares Mendez in the 2017 edition of Spotlight on Young Researchers, the researcher was working on an FNR JUMP project, focussing on developing algorithms for autonomous drones. The robotics scientist has continued to build his research career in Luxembourg – 5 years later, Miguel is a Professor leading a research group with a focus on space robotics.

In nature, we see hyperbolic forms in corals, flatworms, and many other species of reef organisms, such as sponges and kelps. The hyperbolic spaces are also of interest for mathematicians, who are looking to prove the solvability of invariant systems of differential equations in unusual spaces such as these.

Svenja Bourone is a chemist who has always had a fascination for natural sciences. During her master studies at RWTH Aachen, she became captivated by functional nanomaterials and as chance would have it, a doctoral position opened up in just that field. During her AFR PhD, Svenja developed a new protocol to help with the synthesisation of gold nanoparticles, which she is now putting to use in her work as a Postdoc. The Luxembourg national has a strong desire to return home to the Grand Duchy to continue her work on nanomaterials.

Using solar absorbers for collection and storage of heat from the sun is an environmentally friendly way to generate heat, yet only 16% of heating is generated from renewable energy. Material scientists are looking for ways to boost this number by making the solar absorber coatings more efficient.
