Simpson_MikeDr. Michael L. Simpson received his Ph.D. in Electrical Engineering from the University of Tennessee, Knoxville in 1991. He started his research life as an Electrical Engineer, but followed the call of interdisciplinary research to the boundaries between life, computational, and physical sciences. His research has made important contributions to the use of nanotechnology to enable the transfer of information across the biological-synthetic device boundary and the development of a fundamental understanding of Noise Biology.

Simpson has published more than 150 refereed journal papers that have been cited more than 6,000 times, has been awarded 33 patents, and has presented numerous invited talks. His work has been internationally recognized as he is a Fellow of AAAS, the IEEE, and the AIMBE, a Battelle Memorial Institute Distinguished Inventor, and was named the UT-Battelle Distinguished Scientist of the year for 2009. He won the Kermit Fischer Environmental Award and was a finalist for a Discover Magazine Technology Innovation award in 1998, and he serves on the editorial boards of the Journal of Nanomedicine and Biotherapeutic Discovery and the International Journal of Natural Computing Research.

Currently, Simpson is a Distinguished R&D Staff Member and the Group Leader of the Nanofabrication Research Laboratory in the Center for Nanophase Materials Sciences at ORNL, a Professor in the Departments of Material Science and Engineering and Energy Science and Engineering, and the Assistant Director of the Bredesen Center.
