Dr. Christiana Subaar is a lecturer at the department of Physics, College of Science at Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. She graduated from the University for Development Studies, Tamale with B.Sc. degree in Applied Physics and 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 at the University of Cape Coast. Dr. Subaar 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 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 graduating among the best of her class. The Bachelor’s degree in Physics propelled her to pursue a research carrier. 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 carrier led her to pursue a Master’s of philosophy in Medical Physics sponsored by the MathematicsScience and Technology Scholarship Scheme (MASTESS). Prior to enrolling in the University of Ghana, Legon, she resumed her teaching role at the St. John Bosco’s College of Education. Before Colleges of Education fully went on tertiary, she was promoted to the grade of Assistant Director II by Ghana Education Service.  She worked as a senior tutor at the Physics department, taking theoretical and practical classes.

Since joining the department of Physics of KNUST as a lecturer in 2020, Dr. Subaar handles various courses in both the graduate and undergraduate classes and these include Nuclear Science and Technology, Nuclear Physics, Health Physics, Experimental Physics and Biomedical Laboratory. Her research interest is in understanding the safety and pathophysiology associated with radiation diagnosis and treatments. Specifically, Dr. Subaar welcomes graduate students interested in understanding and the use of analytical and applied scientific techniques, to assist the healthcare workers in safety and treatment of patients, in their work such as radiotherapy, x-ray imaging, ultrasound, computed tomography, radiology, nuclear magnetic resonance imaging and lasers. She continues to foster mutually beneficial collaborations with researchers at the Ghana Atomic Energy Commissions, Personnel at the at Korle-Bu teaching hospital and the 37 Military hospitals where she took data for her MPhil and PhD thesis. Dr. Christiana Subaar strives to produce a versatile graduate in the department of Physics, KNUST, as that contributes directly to her own carrier development.
