Four outstanding female researchers receive the "Swiss L'Oréal - UNESCO For Women in Science 2025" award

The new "Swiss L'Oréal - UNESCO For Women in Science" prize was awarded for the first time. The award honours four outstanding female scientists for their excellent research and their commitment to greater equality in science. The award ceremony took place at the Zurich Chamber Orchestra.

The programme is a joint initiative of L'Oréal Switzerland, the Swiss Commission for UNESCO and the SATW. The motto of the programme is "The world needs science - and science needs women" and it was launched in Switzerland for the first time this year. Each award winner receives a grant of 25,000 Swiss francs to continue her research.

The four award winners 2025

Dr Jana Ordon, University of Zurich

Expertise: Plant Immunology and Microbiology

Dr Jana Ordon researches how plants recognise microbes and interact with them, combining genetic, molecular and biochemical approaches. To do this, she closely analyses the processes in the plants' genes and cells. In this way, she finds out which defence mechanisms plants use to stay healthy. Her findings help to make plants more robust and agriculture more sustainable.

Dr Giulia Santoni, EPFL / University of Geneva

Specialism: Neurosciences

Dr Giulia Santoni researches how the human brain develops and why it fails in disease. By further developing 3D brain models from human cells that more closely resemble the adult brain, she hopes to develop personalised therapies for neurological diseases.

Dr Annelies Voordendag, ETH Zurich

Expertise: Geodesy and Glaciology

Dr Annelies Voordendag combines advanced geodetic methods with glaciological field research to precisely monitor glaciers and their response to climate. She uses an innovative marker on the glacier surface - the so-called "ice slider" - which can be tracked with a terrestrial long-range laser scanning system to analyse the movement of glaciers.

Dr Mengyuan Xiao, University of Geneva

Field: Astrophysics and galaxy research

Dr Mengyuan Xiao investigates the origins of ultra-compact galaxies in the early universe. As the leader of major JWST and ALMA telescope programmes, including a Nature study, her work reveals unexpectedly rapid star formation and provides important insights into galaxy formation in the cosmic dawn.

Voices from the partner organisations

We are firmly convinced that Switzerland, as a global leader in innovation, science and research, offers the ideal platform to drive forward the decisive development of women in these areas.

About the programme

Since 1998, Fondation L'Oréal and UNESCO have been supporting outstanding female researchers worldwide with the For Women in Science programme. Since then, over 4400 female scientists from more than 110 countries have been honoured, including seven Nobel Prize winners.

With the launch of the Swiss edition, organised in collaboration with the Swiss Academy of Engineering Sciences SATW, female researchers in Switzerland are now also receiving targeted support. The programme helps to make scientific excellence visible and to promote equal opportunities in research and technology in the long term.
