Dr. Alexandros Charogiannis received his degree in Mechanical Engineering (MEng ) from Imperial College London in 2009, majoring in Vehicle Propulsion Technology. Soon after, he commenced his Ph.D., focusing on the development and implementation of laser-diagnostic techniques in two-phase (gas-liquid) flows relevant to internal-combustion engine research. In 2013, he completed his Ph.D. following the successful defense of his thesis entitled “A laser induced phosphorescence imaging technique for the investigation of evaporating liquid flows”.  At his current role as a post-doctoral researcher at the Chemical Engineering Department, he investigates the effect of flow unsteadiness on the heat and mass transfer performance of thin liquid-film flows. His experiments are based on the application of advanced laser diagnostics such Planar Laser Induced Fluorescence (PLIF), Particle Image and Particle Tracking Velocimetry (PIV/PTV), and Infrared (IR) thermography. Alongside his primary role as an optical diagnostics expert, Alexandros is involved in Ph.D., MSc and occasional research student supervision.
