My responsibilities as team leader was to develop the use of magnetic sensors and magnetic algorithms for detecting and identifying targets of interest. Under DARP auspices, invented a magnetic sensor, the MEMS flux concentrator that solves the problem of 1/f noise. Developed and tested several algorithms for locating magnetic items of interest to the Army. Also showed a modulation technique improved the performance of pezioelectric magnetic sensors while working on another DARPA program, Heterostructural Uncooled Magnetic Sensors. Demonstrated that magnetic permeability changes in amorphous material could be used for long term memory storage. Army Research Laboratory Fellow, Fellows committee that selected internal proposals for possible funding, Military Sensor Symposium (MSS) Fellow, Vice Chairman of MSS Symposia, Contract Officer Representative for the Spin Transfer Torque (STT) RAM DARPA program. STT RAM may become an important energy efficient technology for storing information.

Study of highly correlated electron systems, nanomaterials, and metal matrix composites. Coedited and wrote portions of a book, Nanomaterials: Synthesis, Properties, and Applications published by IOP that provides a broad introduction to the field. Discovered the first or one of first examples of self assembly in nanomaterials. It was found that molybdenum nano cubes formed during sputtering self- arranged into larger 3x3x3 cubes. This discovery was published in Science in 1991.

Development of amorphous superconductors with higher superconducting transition temperatures for power transmission

Studied Kondo systems using specific heat and magnetic susceptibility measurement. Used specific heat measurements of confirm the number of states in the energy gap first observed by my electron tunneling measurements at IBM.

Studied strongly correlated electron systems, supervised gradate research of several students. Bob Majewski received his Ph, D under my supervision. Showed, using neutron scattering measurement, that the spacial distribution of a dilute atom is not altered when it goes into the Kondo state at low temperatures.

Used electron tunneling measurement to study of gapless superconductivity, discovery of anomalous gapless superconductivity, It was found that a small depression of the superconducing transition temperature of lanthanum, caused by alloying with cerium, made it a gapless superconductor. Played a major role in establishing research on concentrated Kondo systems by suggesting that the element cerium was Kondo system. Prior to this suggestion, it was believed that the Kondo effect could only occur in dilute alloys. Subsequent work supported the correctness of this suggestion.

Studied low temperature magnetic ordering and thermometry using adiabatic demagnetization to get to temperatures as low as 40 mil K.

Search for superfluidiity in liquid He 3 at low temperatures by directly measuring the leak rate through nano porous, sintered copper.
