  • Associate Professor, Electrical Engineering
  • Associate Professor, Computer Science

Dr. Law has recently focused his efforts on the fabrication and design of magnetostrictive devices based on environmental friendly composite (such as cellulose nanofibers) and advanced techniques (such as 3D printing process) for devices fabrication. The smart composites and sensors laboratory was setup in collaboration with Dr. El-Hajjar for these research efforts. Previous projects were funded by various agencies including Wisconsin Energy Research Consortium, Defense Advanced Research Projects Agency, U.S. Department of Defense and U.S. National Science Foundation.
