Dr. Josiane P. Lafleur, MBA

Co-Founder and CEO

Josiane has a doctoral degree in Analytical Chemistry (McGill University, Canada). Previously, she was Assistant Professor at the Department of Pharmacy at the University of Copenhagen (Denmark).

“After many years doing research in academia, I decided to finally take the plunge and bring an innovation from the laboratory to the market. I think I can have a positive impact on the world we live in by helping scientists to make new ground-breaking discoveries, improving food safety, environmental monitoring and more.”

Univ.-Prof. Dr. Silvan Schmid

Co-Founder

Silvan has a doctoral degree in Nanomechanics (ETH Zurich).
He is now professor at TU Wien and head of the Research Unit of Micro- and Nanosensors at the Institute of Sensors and Actuator Systems.

“I believe a scientist’s career is defined by their scientific discoveries and their positive impact in the world. We scientists owe it to society to make our discoveries available to everyone. Transforming a research result into a product and making it available to expert users leads to a direct improvement of people’s lives.”
