Biography

Dr. Sadeghi is an Associate Professor in Multiscale Modelling and UKRI Future Leaders Fellow within the School of Engineering and Warwick Centre for Predictive Modelling and head of Device Modelling group.

His main research area is the theory of nanoelectronics and computational material discovery. He collaborates at the interface between physics, chemistry and electronic engineering. He has developed new concepts and methodologies in the theory of nanoscale electronics including innovative strategies for demonstrating, controlling and exploiting quantum and phonon interference for applications in thermoelectricity, switching, sensing and optoelectronics. He is a recipient of two prestigious fellowships, the Leverhulme Trust Early Career Fellowship in June 2017 and the UKRI Future Leaders Fellowship in Feb 2019.

He has published more than 120 peer-reviewed papers in high ranked journals such as Nature, Nat. Mat, Nat. Nano, Nat Comm., Nano Lett. ACS Nano, JACS, Adv. Fun. Mat, Angewadte, Nanoscale. He co-created the next generation quantum transport code "Gollum".
