Donhee Ham, Gordon McKay Professor of Electrical Engineering and Applied Physics, has been awarded $1.7 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) to develop miniaturized nuclear magnetic resonance (NMR) electronics. The devices’ small size and low cost lend themselves to broad deployment in Earth’s deep subsurface, enabling imaging of rock formations for oil and gas exploration.
