Dr. Gerhard Klimeck is a Professor of Electrical and Computer Engineering at Purdue University since Dec. 2003. Since May 2009 he serves as the Director of the National Science Foundation Network for Computational Nanotechnology (NCN) which he led previously led as Technical Director. Before he was the technical group supervisor of the Applied Cluster Computing Technologies Group since April 2002 and a Principal member at the NASA Jet Propulsion Laboratory since Sept. 2001 after joining JPL in February 1998 as a Senior member technical staff. Previously he was a member of technical staff at the Central Research Lab of Texas Instruments (which transitioned to the Applied Research Laboratory of Raytheon). Dr. Klimeck received his Ph.D. in 1994 from Purdue University where he studied electron transport through quantum dots, resonant tunneling diodes and 2-D electron gases. His research for his German electrical engineering degree which he obtained in 1990 from Ruhr-University Bochum concerned the study of laser noise propagation. Dr. Klimeck's work is documented in over 250 peer reviewed publications and over 400 conference presentations, over invited 100 seminars, and over 70 technical reviews. He is a senior member of IEEE, and member of APS, HKN and TBP.
For the NCN he has been directing the replacement of web-form driven online simulation by fully interactive simulations on nanoHUB.org. The change in technology resulted in a seven-fold growth of simulation user numbers to now over 7,400 annual users who run about 400,000 simulations over the web without installing any software. Klimeck has co-authored over 30 tools on nanoHUB which have served over 12,000 so far. nanoHUB.org has alsoe developed into a key resource for up-to-date research topics and educational resources for the community. Over 100,000 users utilize nanoHUB content annually. Klimeck contributed over 160 "nanoHUB and more" content items that have been used by at least 16,000 users. The impact of nanoHUB.org on research can in part be measured in the over 430 citations of nanoHUB in the scientific literature. The impact on education can be assessed in part by the documented 290 classes at over 90 institutions who have used nanoHUB in an educational context.
Gerhard's research interest is in the quantum mechanical modeling of electron transport through nanoelectronic devices, parallel cluster computing, genetic algorithms, and parallel processing. At Purdue he continues to push tight-binding based simulation technology for basic and applied device physics at the nanometer scale utilizing these technical components. He takes pride in creating simulation tools that can tackle realistic nanoelectronic device problems and can be used by other individuals, but computational scientists. At Texas Instruments he served as manager and principal architect of the Nanoelectronic Modeling ( NEMO ) program, the first industrial strength quantum transport tool. NEMO 1-D is still the gold-standard for quantitative resonant tunneling diode simulations. At JPL he led the development of NEMO 3-D which can compute the electronic structure in systems containing up to 52 million atoms. NEMO 3-D applications include quantum dots, quantum wells, and nanowires. At Purdue he is leading a team to combine the NEMO 1-D transport concepts and the NEMO 3-D electronic structure concepts into a new suite of tools entitled OMEN / NEMO. As a cool side project he worked on mars image processing which enabled the integration of parallel processing algorithms in the MIPL data analysis pipeline. The suite of NEMO 1-D, NEMO 3-D, and OMEN have been demonstrated to scale almost perfectly to 23,000, 8,192, and 22,720 cores on today's most advanced parallel computers in the world.
