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 post-doctoral research associate, and in 2005 was converted to limited term technical staff member in the same division. In 2009, he joined Clemson University’s Department of Materials Science and Engineering and Clemson’s Center for Optical Materials Science and Engineering Technologies, COMSET, as a research faculty.

Presently, he is assistant professor with the Dept. of Materials Science and Engineering, and also a researcher affiliated with COMSET and Clemson's Center for Nucleur Environmental Engineering Sciences and Radioacive Waste Management. Dr. Jacobsohn's current research interests are in the areas of scintillators, transparent ceramics, luminescent materials, nanoparticles, and thin films. He has more than 15 years of experience in materials synthesis, processing and characterization and has authored 1 patent issued, 1 book chapter and 104 publications that received more than 1,430 citations to date. His research is or has been funded by the National Science Foundation, the Defense Threat Reduction Agency, Nuclear Energy University Program, Savannnah River National Labaratory, Los Alamos National Laboratory, and the South Carolina Space Grant Consortium through a fellowship to one of his undergraduate students. Dr. Jacobsohn is the recipient of the prestigious National Science Foundation CAREER award in 2017.
