About

Welcome to the Advanced Phase Transformations Research Group. We explore material science and alloy design, unlocking atom movement in solids through composition, stress, and temperature. Our focus is on transformative shifts in atom arrangements, leading to innovative alloys. We're pioneers in alloy design, using a holistic approach that includes Chemistry Design, Process Design, and advanced characterisation. We engineer alloys from scratch to meet specific needs, ensuring both innovation and reliability.

About

Profile

Dr. Gebril El-Fallah was appointed as Lecturer in the Mechanics of Materials Group within the University of Leicester's School of Engineering in early 2022. Before arriving in Leicester, Gebril completed a bachelor's degree in Mechanical Engineering (2013) and a master's degree in Nuclear Engineering from Imperial College London (2015) followed by a PhD at University of Cambridge (2019), where he worked in the Phase Transformations and Complex Properties research group. He was a Research Associate in Cambridge for one year following his PhD, a Teaching Fellow and a Director of Studies at Wolfson College, Cambridge. Gebril also holds a Fellowship of the Higher Education Academy (FHEA).
