Understanding Nanotechnology

Meet Your Workshop Leader

Tihamer "Tee" Toth-Fejel has published articles and presented talks about nanotechnology since 1991. While at General Dynamics Advanced Information Systems as a senior research engineer, he completed two nanotechnology research projects for the NASA Institute for Advanced Concepts. Toth-Fejel is chair of SME's Nanomanufacturing Tech Group, a senior associate of the Foresight Nanotech Institute, on the Advisory Board for The NanoEthics Group, and served on the scientific advisory board of Nanorex.
