About

I am driven by one core ambition: turning advanced physics into technologies that shape the future of industrial measurement, energy efficiency, and digital automation. With a PhD in physical acoustics and over 20 years of experience, I operate at the intersection of deep science, product strategy, and global engineering leadership. Today, as Principal Expert in Ultrasonic Sensors at Endress+Hauser Flow, I help transform cutting‑edge research into robust, scalable solutions—from first principles to series‑ready products deployed worldwide. My work spans ultrasonic flow measurement, sensor and transducer innovation, signal processing, metrology, and experimental validation, across gas and liquid applications. Beyond technology, I focus on building clarity: aligning research, product, manufacturing, and customer needs through technology roadmaps and strong cross‑functional collaboration. I have led international teams, built and transformed engineering organisations, supported M&A technology assessments, and secured public funding for breakthrough energy technologies. I am passionate about empowering engineers, fostering curiosity, and creating environments where innovation delivers real industrial and societal impact.
