O autorze

Dr. Talha Erdem completed his PhD at Bilkent University and is currently a postdoctoral fellow under the prestigious Newton International Fellowship at the Cavendish National Laboratory of the University of Cambridge, UK. His research focuses on DNA-driven self-assembly of colloidal nanocrystals and controlling the optical features of the self-assembled superlattices in real-time, and their applications to lighting displays.

Dr. Hilmi Volkan Demir is a Professor of Electrical Engineering, Physics and Materials Science. He is a Singapore NRF Fellow at NTU Singapore and is the Founding Director of LUMINOUS! Center of Excellence for Semiconductor Lighting and Displays. Concurrently, he holds a chair professorship in materials science and nanotechnology at Bilkent University UNAM – National Nanotechnology Research Center of Turkey. His current research interests include the science and technology of nanocrystal optoelectronics for semiconductor lighting; excitonics and plasmonics for high-efficiency light generation and harvesting; and wireless in vivo sensing and smart implants for future healthcare.
