Williams LefebvreWilliams Lefebvre, Ph.D., is Associate Professor, Materials Physics Group, University of Rouen, France. He received his Ph.D. in Materials Science in Rouen in 2001 for his correlative analysis by transmission electron microscopy and atom probe tomogrphy (APT) of phase transformations in titanium aluminides. He earned a fellowship to the Japan Society for the promotion of science in 2002, when he visited the NIMS of Tsukuba. Since 2014, he has also been a visiting adjunct research associate professor at the University of Nebraska, Lincoln, USA, where has has been leading research activities in the field of physical metallurgy, focusing on light alloys systems, aiming at improving the methodology associated with the investigation of early stages of precipitation by APT and scanning transmission electron microscopy.
