Dr. Mark S. Akselrod is Chief Scientist and Executive Manager of Landauer, Inc. and Adjunct Professor at the Physics Department of Oklahoma State University. He manages Stillwater, Oklahoma, Crystal Growth Division of Landauer Inc.. He received his B.Sc. degree in Mechanical Engineering and Semiconductor Technology from the Urals State Technical University in Yekaterinburg, Russia in 1975 and Ph.D. degree in Solid State Physics from the same university in 1983.
His main research interests and achievements are in the field of radiation solid state physics, crystal growth, optical spectroscopy, luminescence dosimetry and optical data storage. He developed super sensitive Al2O3:C single crystal for radiation dosimetry. Novel Al2O3:C, Mg crystals were developed and patented as two-photon absorbing volumetric Optical Data Storage (ODS) media and Fluorescent Nuclear Track Detector (FNTD). Pulsed Optically Stimulated Luminescence (POSL) dosimetry technique was developed and patented while Dr. Akselrod was working at OSU. It was licensed by Landauer, Inc and commercially used together with Al2O3:C OSL material in LUXEL™ and InLight™ technology and instruments. The results of research have been described in more than 70 papers published in peer reviewed scientific journals and conference proceedings. 10 developments of TL and TSEE materials, technologies and devices have been patented in the former USSR. 15 US patents were obtained for materials and application of optical data storage, optically stimulated luminescence, radiation field imaging, and fluorescent nuclear track detector technology.
Dr. Akselrod is a member of Optical Society of America, American Association of Crystal Growth, International Solid State Dosimetry Organization. He served on the Scientific Advisory Committees of 11th, 12th, 13th, 14th, 15th and 16th Solid State Dosimetry Conferences and is Treasure of the International Solid Sate Dosimetry Organization from 1998 to 2010. He is a reviewer for international scientific journals: "Radiation Measurements", "Journal of Luminescence", "Journal of Crystal Growth" published by Elsevier and "Journal of Radiation Protection Dosimetry" published by Oxford University Press. Invited papers and session chairman at international and national conferences.
