Light at your fingertips

Fingerprints are used to identify criminals, but stop being reliable when damaged. How can we still read them? 🔎 With a state-of-the art imaging technique that shows their inside! Mystery solved, thanks to Egidijus Auksorius, PhD.

MORE ABOUT THE INTERVIEWEE :
Egidijus Auksorius graduated in physics from the University of Vilnius. He received the Ph.D. degree in physics from Imperial College London for work on Fluorescence lifetime imaging and super-resolution STED microscopy.
He then worked as a Research Fellow at Harvard Medical School in Boston and the Institute Langevin in Paris on Full-Field Optical Coherence Tomography (FF-OCT).
He is currently a Principal Investigator at the Centre for Physical Sciences and Technology in Vilnius and a Senior Researcher at the Polish Academy of Science in Warsaw, Physical Optics and Biophotonics Group.
His current research interests include the development and application of FF-OCT for eye imaging.
