Shaikh Ahmed's Linkedin Profile

 

Shaikh Shahid Ahmed received the B.S. degree in electrical and electronic engineering from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 1998, and the M.S. and Ph.D. degrees in electrical engineering from Arizona State University, Tempe, in 2003 and 2005, respectively. From 2005 to 2007, he was a Postdoctoral Research Associate in the School of Electrical and Computer Engineering and at the National Science Foundation (NSF) Network for Computational Nanotechnology (NCN), Purdue University, West Lafayette, Indiana, USA. In August 2007, Shaikh Shahid Ahmed joined Southern Illinois University, Carbondale, Illinois, USA, where he is currently a Full Professor in the Department of Electrical and Computer Engineering.

Research activities in Professor Ahmedís Group focus mainly in the field of computational nanoelectronics and involves multiscale modeling of electronic structure and transport in nanoscale devices including novel transistors, semiconducting 2-D structures and nanowires, quantum dots and nanocrystals, solid-state lighting sources and their reliability, nanoscale thermoelectric and piezoelectric energy-harvesting devices, and nanoelectronic devices for applications in harsh environments. The goal is three-fold: a) better understand the underlying physical processes; b) explore and exploit the enhanced degrees-of-freedom available at nanoscale for device optimization; and c) develop cyber-enabled community nanoelectronics simulation software. Research and computational efforts in Professor Ahmedís group make extensive use of advanced algorithms and state-of-the-art high-performance cluster and CPU/GPGPU distributed computing platforms.

Shaikh Shahid Ahmed is the recipient of 2009 Oak Ridge National Lab/ORAU High-Performance Computing Award and his group has successfully scaled their scientific software on more than 130,000 cores in then Jaguar XT5 fastest supercomputing platform in the world. Professor Ahmed has authored/co-authored 12 nanoelectronics software tools (nanoFET, CNTFET, QuaMC 2D, Schred, nanoMOS, FETtoy, MOSFET, MOScap, QPC, nanoSSL, multiscaleTEC, and MCPT), access to which are freely available on NSFís nanoHUB.org. As of June 6, 2019, these software tools have served over 19,800 individual users worldwide, running more than 860,000 simulations [https://nanohub.org/members/9293/usage]. Shaikh Shahid Ahmed has been the Principal Investigator of the NSF funded Southern Illinois High Performance Computing Research Infrastructure (SIHPCI). He is the recipient of the 2016 Air Force Research Lab Summer Faculty Fellowship, 2013 Dean Juh Wah Chen Outstanding Faculty Award from SIU College of Engineering and 2014 ECE Department Outstanding Teacher Award. He has published over 75 papers in refereed journals and proceedings, authored six book chapters, and contributed to more than 90 technical presentations. He is a senior member of the IEEE, member of the American Physical Society, and member of the HKN Honor Society.
