Dr. Biniyam Nigussie is a senior researcher at Bio and Emerging Technology Institute, Ethiopia. He attended higher education at various Universities. He graduated with a BSc degree in Applied Physics from Hawassa University in 2008, followed by master’s and PhD degrees in Nuclear Physics from Addis Ababa University in 2012 and 2018, respectively. He was one of a select few top students hired as a Graduate Assistant at Haramaya University because of his intense interest in the subject area and diligence. Since then, he provided both undergraduate and graduate students with a variety of physics courses, including Mechanics and Heat, Modern Physics, Modern Optics, Nuclear Physics, Radiation Physics, Sustainable Sources of Energy, Research Methodology, Electronics, and others. He also advised students, and became head of the department of physics, Haramaya University, for almost two years where he played a crucial role for the launching of PhD program at department level. He had joined Technology and Innovation Institute as a researcher in 2019, and worked as a researcher and Director of Technology Research and Development until he recently joined Bio and Emerging Technology Institute as of December 2021, as a researcher. For almost the last three and above years, he has been working as a researcher focusing on the applications of Nuclear Technology, especially Irradiation Technology, for food preservation aiming at attaining food security. Dr. Biniyam has a big interest and passion for the applications of Nuclear Science and Technology for the benefit of the society. In this regard, currently he is engaged in different research projects involving the application of radiation such as “Radiation-Assisted Synthesis of Biodegradable Polymer–Based Nanocomposites”, “Improving Food Safety and Extending Shelf Life of Fresh Fruits and Vegetables Through Gamma Irradiation”, “Improving Lodging Resistance and Seed Size of Tef Through Radiation-Induced Mutation Breeding” and “Evaluation of Mycotoxin Reduction and Changes in the Quality of Hot Pepper and Peanut Treated with Gamma Radiation”.
