In his research, he uses the tools and methods of physics and applies these to today’s most important challenges in electrochemistry. Now, he brings his internationally recognized expertise in nanoscale electrochemistry to Leiden University, where he contributes to pioneering solutions for the energy transition.
‘Serge Lemay is an original and accomplished scientist, and a good friend, who brings a combination of expertise that perfectly fills a gap in the research team in Leiden.’ According to emeritus professor Jan van Ruitenbeek, this appointment as professor marks an important milestone. ‘We are delighted that Serge Lemay will join the Leiden Institute of Physics. At our university, Lemay’s expertise will play a key role in strengthening collaboration between chemistry and physics.’
Exploring chemical reactions with a physicist’s eye
A world-leading scientist in single-entity electrochemistry, Lemay investigates the electrochemical properties of individual particles, viruses and molecules. By applying the tools and methods of physics to some of today’s most pressing challenges in electrochemistry, his work bridges disciplinary boundaries. At our university, this expertise will play a key role in strengthening collaboration between chemistry and physics.
‘This move is a wonderful chance to realign my activities toward more fundamental topics of societal relevance,’ says Lemay. ‘The Leiden provides amazing opportunities to contribute to research and education as part of a top-level team in both physics and chemistry.’
Measuring electrical signals on the smallest scale possible
Lemay works at the very edge of what can be measured. He studies electrical signals in liquids that are so small that normal measuring equipment cannot detect them. To do this, he designs and builds extremely small sensors that combine electronics with tiny fluid channels. These sensors are made using special printing methods called lithography, which can create structures on a very small scale. His work is based on his earlier education in electrical engineering and solid-state.
ANION NWO Gravity
Lemay has a leading role in establishing the national ANION consortium, funded by the NWO Gravity programme. This prestigious funding helped attract him to Leiden, where he will continue to contribute to large-scale collaborative initiatives.
Lemay’s research is very multidisciplinary, drawing on nanotechnology, electronics engineering, biophysics, condensed-matter physics and electrochemistry.
Throughout his career, he has combined fundamental science with strong industrial engagement. He has collaborated extensively with both small and large partners, including for example Intel, Pacific Biosciences, NXP Semiconductors, QurinDiagnostics and Occam Dx.
Lemay’s scientific achievements have been recognised with major grants, including an NWO Vici award and a European Research Council Starting Grant. He has supervised twelve PhD candidates to completion and has held prominent international roles, serving on European research panels and editorial advisory boards.
