Highly Cited Researchers 2025
Two Empa researchers recognized for outstanding impact
Empa researchers Maksym Kovalenko and Zhanyun Wang are among the world's most frequently cited scientists in their respective fields. Their influential contributions have earned them a spot on the prestigious list of Highly Cited Researchers 2025.

Each year, the analytics company Clarivate identifies scientists whose work ranks among the most frequently cited worldwide. Being named a Highly Cited Researcher is a mark of exceptional impact: Only the top one percent of the most frequently cited papers across various research areas are considered. In 2025, two Empa scientists are among the 7131 researchers honored with this distinction – Maksym Kovalenko and Zhanyun Wang.
Expert in functional inorganic materials

Maksym Kovalenko, who also holds a professorship for inorganic materials at ETH Zurich, focuses on developing novel nanoscale, thin-film, and bulk functional materials. The applications of these materials encompass light generation, radiation detection and energy storage. His research on luminescent perovskite quantum dots led to breakthroughs, for which he received numerous awards. This year, Kovalenko appears on the Clarivate list for the eighth time in a row.
Expert in the field of anthropogenic chemicals and materials

Zhanyun Wang is a scientist in Empa's Technology & Society laboratory. His research interests focus primarily on understanding the life cycles and risks of anthropogenic chemicals and materials in the technosphere and natural environment, including per- and polyfluoroalkyl substances (PFAS) as well as plastics and chemicals therein. He is also interested in exploring novel and pragmatic solutions and strengthening the science-policy interface to advance the sound management of chemicals and waste towards a sustainable circular economy. Wang has been on the Clarivate list since 2023.
