Driving the commercialisation, engineering execution, and strategic groundwork to bring RepliClouds to market as an independent deep-tech company.
Dr. Mayur G. Sapkal
Founder
An engineer and climate scientist by training, Mayur holds a doctorate in Atmospheric Science with focus on cloud microphysics from ETH Zurich, alongside degrees in Mechanical Engineering and Atmospheric Sciences. His background in industrial manufacturing — spanning production planning, quality control, and process optimization — ensures RepliClouds instruments are built for robust, real-world deployment.
Mayur developed the HCCNC during his doctoral research, managing its design, fluid dynamics modeling, and laboratory validation before leading the patent filing along with its co-inventors. Having secured an ETH Pioneer Fellowship, he now bridges science and entrepreneurship — leading the technical development of the next-generation HCCNC while driving the business strategy to bring this technology to the global scientific community.
The co-inventors of the HCCNC, alongside senior atmospheric scientists, providing ongoing independent scientific guidance to RepliClouds.
Dr. Zamin A. Kanji
Scientific Advisor
Dr. Zamin Kanji is a senior scientist and lecturer at ETH Zurich's Institute for Atmospheric and Climate Science, where his group studies the physicochemical properties of aerosols and their role in cloud formation. His laboratory has developed and deployed a number of custom atmospheric instruments, including the Zurich Ice Nucleation Chamber (ZINC), the Horizontal Ice Nucleation Chamber (HINC), and its autonomous successor, HINC-Auto.
Zamin is a co-inventor of the HCCNC. He has been involved in the instrument's development from the beginning and continues to advise on its scientific scope and validation.
