In the body, in an organ or even in an individual cell, countless biochemical reactions – the fundamentals of life processes – are underway at any given time, with proteins playing a central role. Ruedi Aebersold, Professor Emeritus of Molecular Systems Biology at ETH Zurich and the University of Zurich, has devoted his research career to finding a way to record all the proteins of a cell or living organism qualitatively and quantitatively at a given point in time (the proteome): in other words, to not only identify the various protein species, but also to determine the quantities in which they are present. For this, he used a mass spectrometry-based analytical methodology, which he then refined on an ongoing basis.
This approach allowed Aebersold to usher in a paradigm shift in favour of the quantitative measurement and systemic observation of proteins, thereby transforming our understanding of organisms and biology in general. The researcher’s efforts have also influenced the field of translational medicine and laid the foundation for the personalised medicine of the future.
“Receiving the Swiss Science Prize Marcel Benoist is a great honour for me and my wonderful team. It also honours the importance of international collaboration between researchers and the open exchange of measurement data – both of which are fundamental to the success of proteomics and to scientific progress more generally,” says Aebersold.
Although Aebersold has been an emeritus professor since the start of this year and has now disbanded his research group, he remains active in research – albeit no longer in the laboratory. He is currently heading an ETH project on tumour profiling, which he will continue to lead until the end of 2023. The project aims to determine the best treatment for individual cancer patients by combining the results of various molecular measurements of their tumour cells (personalised medicine).
For Detlef Günther, Vice President for Research at ETH Zurich, Aebersold is an excellent choice for the award: “There’s almost no other researcher who has developed so many fundamental techniques – and therefore had such a formative influence on a new subject area – as Ruedi Aebersold has done over the course of his career. Today, his outstanding achievements are already an essential prerequisite for successful applications of personalised medicine. As an analytical chemist myself, I am of course particularly pleased that Ruedi Aebersold has been awarded the Benoist Prize in recognition of his scientific work and social engagement.”
The 100th award
The Marcel Benoist Foundation has awarded an annual prize for outstanding research relevant to human life since 1920, which makes Ruedi Aebersold the 100th prizewinner. The prize is worth 250,000 Swiss francs, and this year the Marcel Benoist Foundation and the Fondation Latsis chose the winner together for the first time. The ceremony and prize-giving will take place in Bern on 4 November 2020.
The president of the Marcel Benoist Foundation, Federal Councillor Guy Parmelin, said: “We are delighted by the cooperation with the Fondation Latsis and the first joint awarding of the two prizes. In doing so, we are enhancing Switzerland’s standing as a location for scientific research.” The scientific selection process was conducted by the Swiss National Science Foundation on behalf of both foundations.
