Research, turned into cooler rooms.

Jacinto spent his career studying something quietly fundamental: what happens when light meets matter. His research group at Uppsala University investigates how light is converted into electrical charge in plasmonic systems, using advanced laser spectroscopy to watch it happen. Somewhere in that work sat a practical idea. If you can tune particles to respond to specific wavelengths, you can choose which parts of sunlight to let into a building. That line of research led directly to KulVue, and to founding Duck Technologies.

He is a Full Professor of Physical Chemistry at Uppsala University and an associate professor at the Institute of Physical Chemistry, Polish Academy of Sciences. His training runs across Europe: master’s work at TU Vienna, a PhD from the University of Aberdeen in 2007, then research roles at Queen’s University Belfast, ETH Zürich, the Paul Scherrer Institute, EPFL, and TU Munich.

He builds companies for the same reason he runs experiments: he wants the research to end up somewhere real.
