During his early career, Professor Greer worked in various roles in the semiconductor industry. At United Technologies Mostek, he designed read-only-memory circuits and fabrication processes. At Texas Instruments, he developed models for high frequency bipolar transistors. At the invitation of the Japan Key Technology Center, he investigated atomic scale models for electronic materials at Hitachi’s Central Research Laboratory. In 1992, he was appointed the Quatercentenary Lecturer at Trinity College Dublin as part of the 400th anniversary celebrations marking the founding of the university. His role was to promote high performance computing and multidisciplinary education. He joined the National Microelectronics Research Centre in Cork, Ireland, now Tyndall National Institute, in 1997. There he recruited a team of researchers that are now recognised as world leaders in advanced electronic materials and electronic device physics. His work has led to collaborations with industry giants in electronics technology resulting in funded research projects, joint publications, and knowledge transfer.
Professor Greer was on the management board for the Emerging Nanopatterning Methods (NaPa), a project funded under the European Union’s nanotechnology initiative. The NaPa consortium consisted of 35 groups spread across 14 countries, including laboratories from both industry and academia. Until 2017, he was the director for the European Union excellent science initiative ASCENT tasked with providing access for the global research community to state-of-the-art infrastructure provided by the leading nanoelectronics laboratories in Europe. Professor Greer was recognised by the Government of Ireland as a “Champion of European Union Research”.
He was on the editorial boards of the Journal of Physics: Condensed Matter and the journal Microelectronics Engineering. He is recipient of the “Outstanding Researcher Award in Simulation and Metrology” as selected by the Intel Semiconductor Technology Committee – one of eleven such awards given worldwide. He is co-author of a textbook on nanowire transistors [Nanowire Transistors: Physics of Devices and Materials in One Dimension, Cambridge University Press: Cambridge (2016)]. He is currently on the advisory board for the Institute of Molecular Science and Engineering at Imperial College London.
