Dr. Christiana Subaar is a lecturer at the department of Physics in the College of Science at Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. She graduated from the University for Development Studies, Tamale, with a B.Sc. degree in Applied Physics and a M.Phil. degree in Medical Physics in 2010 and 2014, respectively. Dr. Subaar obtained her Ph.D. degree in Health and Radiation Physics from the University of Cape Coast, sponsored by The Ghana Education Trust Fund (GETFund), in 2018. Dr. Subaar's research during her Ph.D. centered on the temperature changes in the brain during magnetic resonance imaging, an instrumental parameter in the safety of radiation diagnosis.

Dr. Subaar is a professional teacher with over ten (10) years of teaching experience in the basic school after she obtained her 3-year post-secondary Teacher’s Certificate ‘A’ from Bagabaga teacher training college in 2001. She joined the University for Development Studies to study Applied physics, a rare field for an African woman. Her unflinching hard work and dedication saw her graduate among the best of her class. The Bachelor’s degree in Physics propelled her to pursue a research career. Under her mentorship, she helped several undergraduate students with practical and theoretical lessons in her capacity as a Research and Teaching Assistant at the Department of Applied Physics in 2010/2011 academic year. Dr. Subaar’s research career led her to pursue a Master’s of Philosophy in Medical Physics sponsored by the MathematicsScience, and Technology Scholarship Scheme (MASTESS). Prior to enrolling at the University of Ghana, Legon, she resumed her teaching role at St. John Bosco’s College of Education. Before the Colleges of Education fully went on to tertiary education, she was promoted to the grade of Assistant Director II by the Ghana Education Service. She worked as a senior tutor at the Physics department, taking theoretical and practical classes.

Since joining the department of Physics at KNUST as a lecturer in 2020, Dr. Subaar has handled various courses in graduate and undergraduate classes, the undergraduate courses includes Nuclear Physics, Health Physics, Experimental Physics, Biomedical Laboratory and Biomedical Optics from the College of Engineering. The Ph.D. and M.Phil. Nuclear Science and Technology courses also include Diagnostic Radiology and Nuclear Medicine, Clinical Radiology and Radiation Protection, Advanced Nuclear Physics and Neutronics and Radiation Physics and Detection. Her research interest is in understanding the safety and pathophysiology associated with radiation diagnosis and treatments. Her areas of expertise include Magnetic Resonance Imaging, Radiation Dosimetry and Radiation therapy. Her research focus is Paediatric Radiation Dose Optimization Computed Tomography and Digital Radiography Examination in Ghana. for her MPhil and PhD theses. Dr. Christiana Subaar strives to produce a versatile graduate in the department of physics at KNUST, as that contributes directly to her own career development.
