PhD Students
"Currently a Postdoc at Yale University, USA"

Introduction

Rami ElAfandy is a PhD student at King Abdullah University of Science and Technology (KAUST) in the electro-physics division. His current work is related to studying the physical properties (optical, electrical and thermal) of flexible gallium nitride (GaN) nanomembranes and engineering these properties for biological and energy applications. He developed thermal biosensors for living cells and successfully measured and differentiated between different cancer cells based on their thermal transport properties. He also worked on increasing hydrogen photo-generation using indium gallium nitride (InGaN) nanowire membranes.


He received his Master’s Degree of Science in Electrical engineering with a concentration in electromagnetics and photonics from KAUST in which he studied the effect of 2 dimensional and 3 dimensional confinement on the optical and thermal properties of InGaN quantum dots for efficient white light generation.


Rami obtained his bachelor of science in Electrical engineering with a minor in computer science from the American University in Cairo, Egypt in 2009.
