Biography

Professor Dr. Saibal Roy is Research Professor at the School of Physics, National University of Ireland - University College Cork (UCC). He is also Senior Principal Scientist and Head of Micropower Devices & Nanomagnetics research at Tyndall National Institute, Ireland. He is holding Science Foundation Ireland Principal Investigator (SFI PI & FFP) award grants. He did his M.Sc. in Physics from the Indian Institute of Technology, Kharagpur, and received his Ph.D. in Physics/Materials Science from IACS in 1994. Since receiving his Ph.D, his professional experiences include 28 years of academic and 3 years of industrial research; particularly he has served both in academia and industry as a Senior Principal Scientist and head of the research group consisting of large number of Senior Scientists/Researchers/Research engineers. Prof. Roy’s present research interests include how engineered nanostructures could be employed for potential benefits for micron-scale devices from More than Moore (MtM) to beyond Moore (BM) scenario. Since joining the Tyndall National Institute, Prof. Roy was able to bring substantial (> €12 Million) government (SFI, NSF, EU, EI, DETE) and corporate (INTEL, ADI, TI) competitive direct research grants. Prof. Roy has been honored by the president of University College Cork (UCC) for licensing the patented technology to INTEL. Some of his published works on miniaturized energy harvesting devices have featured widely in international media. His micro-fabricated high-frequency inductor/coupled inductors/transformer works have been described as a global benchmark for integrated magnetics by number of leading multinational companies. Prof. Roy has supervised several researchers (~ 50) including Masters/ PhD/ Post-doctoral fellows at Electrical Engineering/Microelectronics/ Physics/ Materials Science, University College Cork, and at Tyndall National Institute. Many of his team members including PhD students and Postdoctora
