Iestyn Pierce is a professor in electronic engineering at the school of Computer Science and Engineering. His research has focused on the numerical modelling of engineering systems, including optical communications components and systems and, more recently, on control systems in low-carbon energy. Iestyn is co-author on more than 30 journal articles and 90 conference publications. He was the leader of the nuclear power work package of the EU-Funded (£4.6m) SEEC project at Bangor University, which led to an interest in distributed wireless sensor networks in forestry management (in mid Wales) and in monitoring saline intrusion in the Mekong Delta in Vietnam, in collaboration with the University of Can Tho Dragon Institute, with initial funding (£22k) from Global Wales.

He chairs the Engineering Centre for North and Mid Wales, a voluntary organisation which provides experiences of the engineering profession to hundreds of school pupils across the region every year.

Iestyn is co-chair of the Science subject panel of the Coleg Cymraeg Cenedlaethol (the Welsh national college for Welsh medium education), having previously chaired the coleg's Physical Sciences panel.

At Bangor he co-supervises an international team project module for engineering students, with collaborators in Mexico, Switzerland, Hong Kong and Vietnam working on interdisciplinary projects, often with an emphasis on sustainable products and services. 

Iestyn is currently working on the design and implementation of distributed, wireless sensor networks with applications in environmental monitoring and distributed power generation.

He has expertise in the deployment of LoRaWAN-based sensor networks in remote environments.

Iestyn is also embarking on a programme of work utilising hardware-in-the-loop simulation methods for electronic control systems in low carbon energy production.
