Stavros Demos is a Senior Scientist and the Group Leader of the Optical Materials Technologies Group at University of Rochester’s Laboratory for Laser Energetics (LLE). He came to LLE in 2016 after almost 20 years as a Scientist at Lawrence Livermore National Laboratory. He received his B.S. in Physics from the University of Ioannina, Greece and his Ph.D. in Physics in 1993 from the City University of New York under the supervision of Prof. Robert Alfano. His thesis work was focused on the understanding of the nonradiative relaxation of active ions in tunable laser materials. His research is focused in the areas of characterization in optical materials and devices for high-power/peak-intensity laser systems and the development of next generation designs and materials. His current research interests also extend to in the fields of additive manufacturing and biomedical optics toward developing instrumentation for rapid and in vivo detection of disease and monitoring of therapeutic intervention. Stavros is a Fellow of the American Physical Society and of the Optical Society of America.
