Dr Hadi Madinei is a Lecturer in the Department of Engineering at Swansea University. His research interests are in the field of nonlinear structural dynamics, with a focus on Micro/Nano-Electro-Mechanical Systems (MEMS/NEMS) and energy harvesters. Dr Madinei has used different modelling techniques to analyse and design a wide range of MEMS sensors and actuators. He is quite expert in developing mathematical models to analyse the vibration of dynamic systems. Dr Madinei is specifically interested in modelling and design of novel MEMS energy harvesters for communications and health monitoring applications.
