Dr. Jacobsohn obtained a B.Sc. in Physics in 1992, a master's degree in Materials and Metallurgical Engineering in 1994, and a D.Sc. in Physics in 1999, all from the Pontifical Catholic University of Rio de Janeiro, Brazil. He joined the Materials Science and Technology Division of Los Alamos National Laboratory in 2002 as a postdoctoral research associate, and in 2005 was converted to a limited-term technical staff member in the same Division. In 2009, he joined Clemson University’s Department of Materials Science as a research faculty. Presently, he is an associate professor with the Department of Materials Science and Engineering and a researcher affiliated with the University’s Center for Nuclear Environmental Engineering Sciences and Radioactive Waste Management (NEESRWM) and the University’s Center for Optical Materials Science and Engineering Technologies (COMSET). Dr. Jacobsohn’s research interests are in the areas of scintillators, OSL dosimeters, and luminescent materials in general, including transparent ceramics, nanoparticles, glasses, single crystals, and thin films. He has more than 20 years of experience in materials synthesis, processing, and characterization. According to Web of Science, he has authored and co-authored 1 patent issued, 1 book chapter, and more than 120 publications that received more than 1840 citations to date. He co-chaired the 6th International Workshop on Photoluminescence in Rare Earths: Photonic Materials and Devices (PRE’16) in 2016 and was the Managing Guest Editor of the conference proceedings published as a special issue of Optical Materials in 2017. He is a member of the Organizing Committee of the 16th International Conference on Scintillating Materials and their Applications (SCINT), Santa Fe, NM, September 16-24, 2021, and co-organizer of the symposium “Application of Luminescent Materials for Radiation Detection” as part of the International Chemical Congress of Pacific Basin Societies (Pacifichem), Honolulu, HI, December 16-21, 2021. His research is or has been funded by the National Science Foundation (NSF), the Defense Threat Reduction Agency (DTRA), Nuclear Energy University Program (NEUP), Savannah River National Laboratory (SRNL), Los Alamos National Laboratory (LANL), and the South Carolina Space Grant Consortium through a fellowship to one of his undergraduate students. Dr. Jacobsohn was the recipient of the prestigious NSF CAREER award in 2017, of the Award for Excellence from the Board of Trustees of Clemson University in 2018, of the Dean’s Professorship Award from the College of Engineering, Computing and Applied Sciences of Clemson University also in 2018, and of the David and Mary Ann Bishop Dean’s Professorship Award in 2020.
