About
I am a scientist at heart, trained as both a physicist and an engineer, with a deep fascination for harnessing light as a powerful diagnostic tool. My research uniquely blends applied optics, materials engineering, and bio/chemical sensing, creating customized nano-interfaces and fiber-integrated sensor systems that tackle critical issues in medical diagnostics, environmental monitoring, and agro-food safety.
Currently, I lead the Alexander von Humboldt Foundation-funded project, developing a Lab-on-Fiber System for on-site breath analysis. This innovative technology offers transformative capabilities for managing respiratory conditions in personalized healthcare settings enabling routine profiling of breath volatile organic compounds. Additionally, I have been contributing to the EU SOILMONITOR project, designing bioinspired chemical assays for precise detection of soil nutrients in microfluidics, to support sustainable agriculture.
My research is inspired by everyday challenges that significantly impact human health, whether rooted in disease, pollution, or environmental changes. A core mission of mine is to bridge the critical health gap in respiratory care through patient-centered breath profiling. What drives me most is the lack of a personalized digital breath profiling platform that enables both individuals and clinicians to effectively monitor, predict, and manage health conditions. This mission combines scientific rigor with human empathy, addressing the unmet needs of countless parents and children worldwide.
Looking forward, my vision is to deliver essential, cutting-edge technologies that advance personalized digital healthcare and environmental sustainability. Equally important to me is mentorship, promoting gender equality in science, and fostering inclusive research environments where early-career researchers can thrive.
I welcome connections with peers, researchers, clinicians, startups, and industry partners who share this passion. Let's work together to expand the limits of what science can accomplish for society.
