Achilleas Savva, PhD

Postdoctoral Fellows


Research Interests

Achilleas’s current research interests lie on the understanding of ionic and electronic conduction mechanisms in organic semiconductor films. He investigates mixed conduction using a combination of advanced electrochemical characterization techniques. He aims to design organic electronic materials and devices that can efficiently interface human body for recording biological signals.​
