Biography
Dr Ansari is a senior staff research scientist at the Micro-Nano Systems (MNS) Centre, Tyndall National Institute, University College Cork (UCC), Ireland. She has received her PhD in Microelectronics from Tyndall, UCC in 2013 and awarded best PhD student BOC bursary for her PhD research work in 2012. Her doctoral research work was focused on atomic-scale simulation of nanoelectronic devices. She was then awarded Irish Research Council (IRC) fellowship on developing semimetal-based nanosensors.
Dr Ansari was on the Technical Program Committee and one of the local organisers of the IEEE NANO conference held at UCC in July 2018.
Dr. Ansari’s activities involve Emerging Materials and Devices for future nanoelectronic, ICT and spintronics applications, including simulation of emerging device concepts. Dr Ansari’s research focus is on addressing key technological challenges that are essential to the future evolution of Integrated Circuits (ICs) beyond Moore’s Law, needed for the future Trillion Sensor economy of the Internet of Things (IoT), and smart systems/cities. She has gained a wealth of experience in nano-scale material simulations and design of electronic devices through collaborative projects with industry, and by delivering industry-level, high-standard and high-impact research. In particular, her research interest is low dimensional semiconductors and semimetals for beyond classical CMOS integration, surface effects in nanowires and other low-dimensional systems, atomic scale models for nanowire transistors and emerging device concepts.
Dr Ansari has had collaborative research projects or technical engagements with international industrial multinationals, including Intel and TSMC. She is the lead inventor of a US patent (US 10658460 B2) and an invention disclosure on “semimetal-based devices”.
Over the past 10 years she has been a technical reviewer for peer-reviewed journals including ACS Applied Materials and Interfaces, IEEE Transactions on Electron Devices, Applied Physics Letters, and Journal of Applied Physics among others.
Her role involves:
– project management,
– budget management and purchasing,
– PhD student supervision and mentoring,
– dissemination of results in peer-reviewed articles.
