Dr. Eleni Makarona is a physicist with a career path in silicon-based optical biosensors, optoelectronics, and nanostructured materials. She holds a BSc in Physics from the National and Kapodistrian University of Athens (1998) and an MSc (2000) and PhD (2004) in Physics from Brown University, where her research focused on III-Nitride ultraviolet light-emitting devices. Currently serving as Director of Research at the Institute of Nanoscience and Nanotechnology (NCSR “Demokritos”), she has authored over 70 publications (75% in Q1), delivered 120+ conference presentations, and holds seven patents. Eleni is an Associate Editor for Optics & Laser Technology, serves on the editorial boards of Sensors and Chips, reviews for 20+ international journals, and evaluates research proposals for European and national bodies. She is also an elected member of the NCSR “Demokritos” Board of Directors. Her work has been recognized with the L’Oréal-Unesco Award for Young Women in Science (2010, Greek Chapter), and her h-index of 22 showcases her contributions to photonics, biosensors, and nanotechnology.

Eleni’s research is deeply rooted in real-world applications, with a focus on delivering solutions that can truly make a difference. She has contributed to the development of Photostick, an innovative biodiagnostic technology designed to be an affordable, user-friendly tool that bridges the gap between cutting-edge science and practical, everyday use. Though still in the process of commercialization, this project embodies her vision to push the frontiers of biodiagnostics, drug development, food safety, and environmental monitoring, while ensuring the technology remains accessible to all. Eleni is dedicated to ensuring that this tool, "for geeks, made by geeks," reflects the rigor and potential of the science behind it, transforming years of research into an accessible solution that meets real-world needs.

A dedicated mentor and advocate, Eleni’s approach to science is as much about nurturing young minds as it is about breaking new ground. She has supervised numerous student theses, trying to inspire future researchers to think beyond conventional boundaries. Eleni is also a passionate champion for diversity in STEM, believing that inclusive innovation is the key to solving today’s most pressing challenges and taking that stand publicly. She envisions a future where science not only pushes the frontiers of technology but also fosters social equity, creating opportunities for all and contributing to a more sustainable and just world.
