Welcome to my page. My name is Guy Vosco, and I am a PhD student in the Refaely-Abramson Group at the Weizmann Institute of Science.

My research explores the interaction between light and matter in low-dimensional materials, examining how these materials absorb and emit light, and how their fundamental properties influence applications such as efficient solar cells and advanced quantum devices. I use ab-initio computational methods including GW, Bethe–Salpeter Equation (BSE), and Density-Functional Perturbation Theory (DFPT) to study how excitons (bound electron–hole pairs) and phonons (quantized vibrations of the crystal lattice) affect the optical and electronic behavior of materials.
