The citation of scientific papers by others is considered an indicator of relevant, interesting research. Reference and citation database Web of Science counts and indexes citations, then publishes an annual list of the top 1% most-cited researchers in various fields.
For the third year running, Chalmers has no fewer than three researchers on this list: Anders Lyngfelt and Tobias Mattisson in the field of technology and Jens Nielsen in the field of biology and biochemistry.
Visibility far beyond Sweden
“For a small university like Chalmers, it means a great deal to have three researchers on this prestigious list. It gives us visibility far beyond Sweden and Europe and shows that our research is world-class, contributing to the development of science and society,” says Mats Viberg, First Vice President with responsibility for research at Chalmers.
Anders Lyngfelt and Tobias Mattisson are Professor and Associate Professor respectively at the Division of Energy Technology. They have jointly developed a combustion technology, known as “chemical-looping combustion” in which waste carbon dioxide is extracted separately rather than being mixed with air. The technology makes it simple and cheap to capture carbon dioxide instead of releasing it into the atmosphere. There are currently 34 pilot installations of chemical-looping combustion all around the world.
Cleaning up old emissions
More recently, Lyngfelt and Mattisson’s research has focused on replacing fossil fuels with biomass. This means that instead of preventing fresh atmospheric CO2 emissions, they can clean up old ones.
Jens Nielsen, Professor of Systems Biology, works at the interface between engineering and biology. Systems biology is a relatively new research area which uses mathematical models to understand systems in living organisms.
Altering yeast cell metabolism
Nielsen’s research group has made significant progress in rearranging the metabolism of yeast cells to make them produce chemical components for use in biofuels. The group is also employing the same principles in its work on medical applications. This involves understanding how diseases like diabetes, cancer and liver disease work and then getting genetically modified yeast or human cells to produce protein drugs that can treat the diseases.
During the autumn, Nielsen has been awarded several prizes and distinctions for his research.
Guest professor also listed
Also on the most-cited list is electrical energy technology researcher, Remus Teodorescu, from Aalborg University in Denmark. He has been a guest professor at Chalmers throughout his four years on the list.
“It’s great to also have a guest professor on the list. It’s important for us to establish links with strong researchers and research settings in other countries. It means we can bring in knowledge and influence as well as reaching out with what Chalmers can offer,” says Mats Viberg.
