Biography

Robert A. Hughes joined the Department of Aerospace and Mechanical Engineering at the University of Notre Dame as a Research Associate Professor in 2016. He has also held positions as a Research Professor at Temple University and as a Research Scientist at the Brockhouse Institute for Materials Research. He obtained his Ph.D. and M.Sc. in physics from McMaster University (Hamilton, Canada). 

Summary of Activities/Interests

His primary area of expertise is in materials synthesis, characterization, and application. The scope of materials investigated include: (i) plasmonic nanostructures, (ii) bulk and nanoscale catalysts, (iii) ferroelectrics, (iv) semiconducting nanowires, (v) II-VI semiconductor films, (vi) shape memory alloys, (vii) metallic oxides, and (viii) high temperature superconductors. The material synthesis techniques used are diverse and include self-assembly, directed-assembly, seed-mediated solution phase syntheses, pulsed laser deposition, sputter deposition, and both conventional and unconventional evaporation techniques. He is currently pursuing applications in the areas of plasmonics, catalysis, photocatalysis, and chemical sensing.
