Iyabo Usman received a BSc(Hons) degree from LAUTECH, Nigeria in 1999 and her MSc (2007) and PhD (2009) in Nuclear Physics from the University of the Witwatersrand, Johannesburg, South Africa. From 2010 to 2012, she was a postdoctoral researcher at iThemba LABS, Cape Town where she worked on the development of zero-degree facility of the K600 magnetic spectrometer. She joined the School of Physics, University of the Witwatersrand in 2012 as a Lecturer. Prof Usman is currently the Leader of the Nuclear Structure Research Group (NSRG) in the School of Physics at the University of the Witwatersrand. During the winter of 2014 she was a Visiting Scholar in the Nuclear Engineering Department at the University of Tennessee, Knoxville, and also in the Nuclear Science and Engineering Division of Argonne National Laboratory, Lemont, Illinois during the first half of 2019. Her research interests include experimental nuclear structure physics, environmental radiation physics, nuclear materials, as well as nuclear security and forensics. Much of her work has been on the investigation of nuclear giant resonances across the periodic table through medium energy experiments using the light ion beams available at the iThemba LABS SSC cyclotron in conjunction with the state-of-the-art K600 magnetic spectrometer, and supervision of postgraduate students. She is an executive member of the Council of the South African Institute of Physics (SAIP), Chairperson of the South African Network for Nuclear Education Science and Technology (SANNEST) and iThemba LABS Users, and has been a South African National Research Foundation (NRF) rated researcher since 2013.

Prof Manny Mathuthu joined the North-West University (Mafikeng campus) in August 2012 as an Associate Professor of Applied Radiation Science and Technology. To date he is a Full Professor specializing in Nuclear Forensics. In 2022, I was the Acting Director for the Center for Applied Radiation Science and Technology (CARST), at the North-West University-Mafikeng Campus.
As an academic, he has consistently delivered academic balance in Research, Teaching and Learning outputs, managing Projects valued as high as R5,000,000.00 and supervising around 6-8 PhDs and 4-6 MScs per year. In 2014, he developed the first ever CARST PhD Programme in Nuclear Security, Medical Physics and Nuclear Physics, etc. In the year 2018, Prof Mathuthu was awarded the C3 Rating (for an Established Researcher) by the National Research Foundation of South Africa. In the same year I was awarded the Prestigious IAEA Fellowship for Training in Nuclear Forensics at the Tennessee University in the USA. This has resulted in us developing our Nuclear Forensics LAB at CARST.

Prof. Nnamdi N. Jibiri was born on 4 June 1969 in Ihioma in Orlu LGA Imo State Nigeria. He obtained his Ph.D in Physics from the University of Ibadan Nigeria in 2000 with special interest in Radiation and Health Physics. He has over 30 years of University teaching and Research experience in both ionizing and non-ionizing radiation. His research work cut across the following; Radioactivity measurements in food samples in Nigeria, effects of food diet preparation on ingestion dose to humans, radioactivity studies in environmental matrices, environmental impact assessment, research and development, radiation protection and optimization in x-ray diagnostic procedures, radioactivity dynamical modeling, Ionizing and non –ionizing Radiation Protection and Safety.
He has earned the prestigious research grant award by International Foundation for Science (IFS), Sweden for six years on research on food radioactivity and effective ingestion dose evaluation to humans from two naturally elevated background radiation areas in Jos and Abeokuta, Nigeria. He has also developed simple radiochemical analytical techniques in the determination of Polonium-210 in Nigeria cigarettes as a guest researcher at National Institute for Standard and Technology (NIST), Maryland USA under a research grant by Mac Arthur Foundation. He has won other research grants and fellowships including that of Association of Africa Universities (AAU).
Prof. Jibiri has been involved in some pilot studies on the assessment of effects of em-waves emissions from the base stations of major GSM carriers in Nigeria and has equally carried out some research work on the effects of radio-frequency emissions from GSM base stations in Nigeria and is a resource person to Nigerian Communications Commission (NCC) on non-ionizing radiation emission safety.
Presently has to his credit over 120 published research articles in reputable local and international journals.
